Rooppur consignment on sanctioned Russian ship may come by road from India
The consignment meant for the Rooppur Nuclear Power Plant (NPP) that had to be turned away from Bangladesh shores due to being carried by a US-sanctioned vessel, may ultimately be sent to their destination by road. This is based on indications that the Russian ship, instead of going all the way back with the vital equipment it was carrying, has hovered in the Bay of Bengal since the incident in late December. Now the BBC is reporting that it may be looking to unload its consignment at the Haldia port in West Bengal. India has been openly defying US sanctions on Russian ships since the start of the war in Ukraine. All Indian ports are thus open to Russia-flagged vessels, even those with sanctions on them.

"We have learned that the cargo from the vessel can be unloaded at the Haldia port in India's West Bengal. From there, another vessel could carry the consignment for the Rooppur power plant and deliver it to a port of Bangladesh," he added. Sadhan Kumar, operations officer of Khulna Conveyor Shipping Lines, said: "Earlier shipments for Rooppur NPP were delivered by Russian and neutral, foreign-flagged vessels at the Mongla port. After the unloading of the cargoes at the port, they would be taken to Rooppur."

Ukraine: Russia put rocket launchers at nuclear power plant
Russian forces have installed multiple rocket launchers at Ukraine's shut-down Zaporizhzhia nuclear power plant, Ukrainian officials claimed Thursday, raising fears Europe's largest atomic power station could be used as a base to fire on Ukrainian territory and heightening radiation dangers. Ukraine's nuclear company Energoatom said in a statement that Russian forces occupying the plant have placed several Grad multiple rocket launchers near one of its six nuclear reactors. It said the offensive systems are located at new “protective structures” the Russians secretly built, "violating all conditions for nuclear and radiation safety.” The claim could not be independently verified. The Soviet-built multiple rocket launchers are capable of firing rockets at ranges of up to 40 kilometers (25 miles), and Energoatom said they could enable Russian forces to hit the opposite bank of the Dnieper River, where each side blames the other for almost daily shelling in the cities of Nikopol and Marhanets. The plant is in a southern Ukrainian region the Kremlin has illegally annexed. The Zaporizhzhia station has been under Russian control since the war’s early days. Russia and Ukraine accuse each other of shelling the plant and risking a radiation release. Although the risk of a nuclear meltdown is greatly reduced because all six reactors have been shut down, experts have said a dangerous radiation release is still possible. The reactors were shut down because the fighting kept knocking out external power supplies needed to run the reactors' cooling systems and other safety systems. Read more: Ukraine leader defiant as drone strikes hit Russia again The U.N.'s nuclear watchdog, the International Atomic Energy Agency, has stationed inspectors at the plant and has been trying to persuade both sides in the conflict to agree to a demilitarized zone around it. The agency did not immediately respond to a request for comment about the reported Grad installation. Ukraine has accused the Russians before of having heavy weapons at the plant. The Kremlin has said it needs to maintain control of the plant to defend it from alleged Ukrainian attacks. With renewed focus on the dangers at Zaporizhzhia in the war, dragging on past nine months, the Kremlin is sending new signals about how to end it. It said Thursday it’s up to Ukraine’s president to end the military conflict, suggesting terms that Kyiv has repeatedly rejected, while Russian President Vladimir Putin vowed to press on with the fighting despite Western criticism. Kremlin spokesman Dmitry Peskov said that "(Ukrainian President Volodymyr) Zelenskyy knows when it may end. It may end tomorrow if he wishes so.” The Ukraine war has deteriorated relations between Russia and much of the rest of the world, but limited cooperation continues in some areas, such as exchanges of prisoners. On Thursday, in a dramatic swap that had been in the making for months, Russia freed American basketball star Brittney Griner while the United States released a jailed Russian arms dealer. The Kremlin has long said that Ukraine must accept Russian conditions to end the fighting. It has demanded that Kyiv recognize Crimea — a Ukrainian peninsula that Moscow illegally annexed in 2014 — as part of Russia and also accept Moscow’s other land gains in Ukraine. Zelenskyy and other Ukrainian officials have repeatedly rejected those conditions, saying the war will end when the occupied territories are retaken or Russian forces leave them. In an acknowledgement that it’s taking longer than he expected to achieve his goals in the conflict, Putin said Wednesday that the fighting in Ukraine “could be a lengthy process” while describing Moscow's land gains as “a significant result for Russia." During a conference call with reporters, Peskov said Moscow wasn’t aiming to grab new land but will try to regain control of areas in Ukraine from which it withdrew just weeks after incorporating them into Russia in hastily called referendums — which Ukraine and the West reject as illegal shams. After earlier retreats from the Kyiv and Kharkiv areas, Russian troops last month left the city of Kherson and parts of the Kherson region, one of the four illegally annexed Ukrainian regions. Read more: Russian airfield hit, a day after drone strikes on bases Putin vowed Thursday to achieve the declared goals in Ukraine regardless of the Western reaction. “All we have to do is make a move and there is a lot of noise, chatter and outcry all across the universe. It will not stop us fulfilling combat tasks,” Putin said. He described Russian strikes on Ukraine’s energy facilities and other key infrastructure as a legitimate response to an Oct. 8 truck bombing of a key bridge linking Crimea with Russia’s mainland, and other attacks the Kremlin claimed Ukraine carried out. Putin also cited Ukraine’s move to halt water supplies to the areas in eastern Ukraine that Russia controlled. “There is a lot of noise now about our strikes on the energy infrastructure,” Putin said at a meeting with soldiers whom he decorated with the country’s top medals. “Yes, we are doing it. But who started it? Who struck the Crimean bridge? Who blew up power lines from the Kursk nuclear power station? Who is not supplying water to Donetsk?” While stopping short of publicly claiming credit for the attacks, Ukrainian officials welcome their results and hint at Ukrainian involvement. Heavy fighting continues, mostly in regions Russia annexed. Zelenskyy's office said 11 civilians were killed in Ukraine Wednesday. The Donetsk region has been the epicenter of the recent fighting. Russian artillery struck the town of Yampil during distribution of humanitarian aid to civilians, Ukrainian officials said. Buildings were damaged in Kurakhove, 35 kilometers (22 miles) west of the regional capital, Donetsk, officials said. More than ten cities and villages in the region were shelled, including the town of Bakhmut, which has remained in Ukrainian hands despite Moscow’s goal of capturing the entire annexed Donbas region bordering Russia.
PM inaugurates installation of 2nd reactor at Rooppur nuclear power plant
Prime Minister Sheikh Hasina today (Oct 19, 2022) inaugurated the installation of the second and final reactor at the country's first Rooppur nuclear power plant. The reactor pressure vessel was installed at the second unit of the 2,400 MW Rooppur nuclear power plant (RNPP). She joined the programme virtually from her official residence Ganabhaban while it was held in Ishwardi of the northern district of Pabna. The country’s lone nuclear power plant, being constructed at Rooppur in Ishwardi at a total cost of US$ 12.65 billion, has two units with a power generation capacity of 1200 MW each. Read: Bridge cranes installed at Unit 2 of Rooppur NPP In October last year, the prime minister inaugurated the reactor pressure vessel of the plant's first unit. According to the Rosatom, the Russian contractor of the project, the VVER-1200 reactor vessel passed the input control in accordance with all regulatory requirements before its installation Wednesday. Rosatom officials said the operation to install the VVER-1200 reactor vessel of the second power unit in the design position was carried out in several stages. A Liebherr-11350 heavy crawler crane lifted the reactor vessel onto the transport portal of the power unit. Read PM to open installation of reactor pressure vessel at Rooppur Power Plant's 2nd unit Wednesday Then, on a special transport trolley, it was moved to the central hall of the reactor compartment. Further, with the help of a polar crane, the reactor vessel was turned into a vertical position and installed on a support ring in the reactor shaft. According to the RNPP officials, the first unit of the project has already made 70 per cent progress in physical work, and with the installation of the reactor pressure vessel at the second unit the project will have overall 53 percent of physical work completed. “With the installation of the reactor pressure vessel, the project’s second unit’s physical work will achieve over 45 per cent of the target”, Dr Md Shawkat Akbar, the project director in the country’s biggest scheme in power generation, told UNB on Tuesday. Read Fourth Russian shipment for Rooppur arrives at Mongla Port The government undertook the project in 2009 and after a long discussion signed an $11.385 billion credit agreement with Russian Federation on July 26 in 2016 to implement the project through appointing the Russian state nuclear energy firm—Rosatom--as its contractor. In addition, on August 6, 2019, Bangladesh signed a nuclear fuel supply agreement with Russia for the project. Under the deal, the Russian state-owned nuclear fuel firm TVEL Joint Stock Company will supply nuclear fuel for the entire life span of the power plant. Read Rooppur NPP: Hydro-accumulators’ testing begins in Russia Each unit of the power plant will have to reload one-third of the total required nuclear fuel after every 18 months and the first, second and third reloads will be provided by the Russian firm free of cost. Each reloading of nuclear fuel will cost $62 million, equivalent to Tk 550 crore. Shawkat informed that after the installation of the pressure vessel at the second unit, the major work that will remain unfinished include pre-operational testing and fuel loading. “We hope, we’ll perform these work by June next year”, he said adding, some more work will be required to be completed before commissioning the project. Read Manufacturing of hydro-accumulators of Rooppur NPP underway “Construction of power grid line and building of communication and security systems are among the important work required to be completed before mid 2024”, he said. The second half of the year 2024 is set to be the deadline to start commercial operation of the 1200 MW first unit of the nuclear power plant while the second unit in 2025, said Shawkat, also managing director of the Nuclear Power Company Bangladesh Limited (NPCBL), a dedicated company to deal with nuclear power plant. Initially, a target was set to start the commercial operation of the first unit from 2022 and second unit from 2023 and then the target was deferred. Read Auxiliary reactor building construction at Rooppur unit-1 ends ahead of schedule Officials of the NPCBL said about 14,000 foreign workers from different western countries, including Russia and Belarus, are now engaged in the Rooppur nuclear power plant project under the contractor and its sub-contractors to execute different works.
Ukrainian fears run high over fighting near nuclear plant
Ukrainians are once again anxious and alarmed about the fate of a nuclear power plant in a land that was home to the world’s worst atomic accident in 1986 at Chernobyl. The Zaporizhzhia nuclear plant, Europe’s largest, has been occupied by Russian forces since the early days of the war, and continued fighting near the facility has heightened fears of a catastrophe that could affect nearby towns in southern Ukraine — or potentially an even wider region. The government in Kyiv alleges Russia is essentially holding the Soviet-era nuclear plant hostage, storing weapons there and launching attacks from around it, while Moscow accuses Ukraine of recklessly firing on the facility, which is located in the city of Enerhodar. “Anybody who understands nuclear safety issues has been trembling for the last six months,” said Mycle Schneider, an independent policy consultant and coordinator of the World Nuclear Industry Status Report. Ukraine cannot simply shut down its nuclear plants during the war because it is heavily reliant on them, and its 15 reactors at four stations provide about half of its electricity. Still, an ongoing conflict near a working atomic plant is troubling for many experts who fear that a damaged facility could lead to a disaster. That fear is palpable just across the Dnieper River in Nikopol, where residents have been under nearly constant Russian shelling since July 12, with eight people killed, 850 buildings damaged and over the half the population of 100,000 fleeing the city. Liudmyla Shyshkina, a 74-year-old widow who lived within sight of the Zaporizhzhia plant before her apartment was bombarded and her husband killed, said she believes the Russians are capable of intentionally causing a nuclear disaster. Fighting in early March caused a brief fire at the plant’s training complex, which officials said did not result in the release of any radiation. Ukrainian President Volodymyr Zelenskyy says Russia’s military actions there amount to “nuclear blackmail.” No civilian nuclear plant is designed for a wartime situation, although the buildings housing Zaporizhzhia’s six reactors are protected by reinforced concrete that could withstand an errant shell, experts say. The more immediate concern is that a disruption of electricity supply to the plant could knock out cooling systems that are essential for the safe operation of the reactors, and emergency diesel generators are sometimes unreliable. The pools where spent fuel rods are kept to be cooled also are vulnerable to shelling, which could cause the release of radioactive material. Kyiv told the International Atomic Energy Agency, the U.N.’s nuclear watchdog, that shelling earlier this week damaged transformers at a nearby conventional power plant, disrupting electricity supplies to the Zaporizhzhia plant for several hours. “These incidents show why the IAEA must be able to send a mission to the Zaporizhzhia nuclear power plant very soon,” said the agency’s head, Rafael Mariano Grossi, adding that he expected that to happen “within the next few days, if ongoing negotiations succeed.” At a U.N. Security Council meeting Tuesday, U.N. political chief Rosemary DiCarlo urged the withdrawal of all military personnel and equipment from the plant and an agreement on a demilitarized zone around it. Currently only one of the plant’s four power lines connecting it to the grid is operational, the agency said. External power is essential not just to cool the two reactors still in operation but also the spent radioactive fuel stored in special facilities onsite. Read: 22 reported killed in Independence Day attack in Ukraine “If we lose the last one, we are at the total mercy of emergency power generators,” said Najmedin Meshkati, a professor of civil and environmental engineering at the University of Southern California. He and Schneider expressed concern that the occupation of the plant by Russian forces is also hampering safety inspections and the replacement of critical parts, and is putting severe strain on hundreds of Ukrainian staff who operate the facility. “Human error probability will be increased manifold by fatigue,” said Meshkati, who was part of a committee appointed by the U.S. National Academy of Sciences to identify lessons from the 2011 nuclear disaster at Japan’s Fukushima nuclear plant. “Fatigue and stress are unfortunately two big safety factors.” If an incident at the Zaporizhzhia plant were to release significant amounts of radiation, the scale and location of the contamination would be determined largely by the weather, said Paul Dorfman, a nuclear safety expert at the University of Sussex who has advised the British and Irish governments. The massive earthquake and tsunami that hit the Fukushima plant destroyed cooling systems which triggered meltdowns in three of its reactors. Much of the contaminated material was blown out to sea, limiting the damage. The April 26, 1986, explosion and fire at one of four reactors at the Chernobyl nuclear plant north of Kyiv sent a cloud of radioactive material across a wide swath of Europe and beyond. In addition to fueling anti-nuclear sentiment in many countries, the disaster left deep psychological scars on Ukrainians. Zaporizhzhia’s reactors are of a different model than those at Chernobyl, but unfavorable winds could still spread radioactive contamination in any direction, Dorfman said. “If something really went wrong, then we have a full-scale radiological catastrophe that could reach Europe, go as far as the Middle East, and certainly could reach Russia, but the most significant contamination would be in the immediate area,” he said. That’s why Nikopol’s emergency services department takes radiation measurements every hour since the Russian invasion began. Before that, it was every four hours.
Shift in war's front seen as grain leaves Ukraine; plant hit
Six more ships carrying agricultural cargo held up by the war in Ukraine received authorization Sunday to leave the country’s Black Sea coast as analysts warned that Russia was moving troops and equipment in the direction of the southern port cities to stave off a Ukrainian counteroffensive. Ukraine and Russia also accused each other of shelling Europe's largest nuclear power plant. The loaded vessels were cleared to depart from Chornomorsk and Odesa, according to the Joint Coordination Center, which oversees an international deal intended to get some 20 million tons of grain out of Ukraine to feed millions going hungry in Africa, the Middle East and parts of Asia. Ukraine, Russia, Turkey and the United Nations signed the agreements last month to create a 111-nautical-mile sea corridor that would allow cargo ships to travel safely out of ports that Russia’s military had blockaded and through waters that Ukraine’s military had mined. Implementation of the deal, which is in effect for four months, has proceeded slowly since the first ship embarked on Aug. 1. Four of the carriers cleared Sunday to leave Ukraine were transporting more than 219,000 tons of corn. The fifth was carrying more than 6,600 tons of sunflower oil and the sixth 11,000 tons of soya, the Joint Coordination Center said. Three other cargo ships that left Friday passed their inspections and received clearance Sunday to pass through Turkey’s Bosporus Strait on the way to their final destinations, the Center said. However, the vessel that left Ukraine last Monday with great fanfare as the first under the grain exports deal had its scheduled arrival in Lebanon delayed Sunday, according to a Lebanese Cabinet minister and the Ukraine Embassy. The cause of the delay was not immediately clear. Ukrainian officials were initially skeptical of a grain export deal, citing suspicions that Moscow would try to exploit shipping activity to mass troops offshore or send long-range missiles from the Black Sea, as it has done multiple times during the war. The agreements call for ships to leave Ukraine under military escort and to undergo inspections to make sure they carry only grain, fertilizer or food and not any other commodities. Inbound cargo vessels are checked to ensure they are not carrying weapons. Read:Ukraine grain headed for Lebanon under wartime deal delayed In a weekend analysis, Britain's Defense Ministry said the Russian invasion that started Feb. 24 “is about to enter a new phase” in which the fighting would shift to a roughly 350-kilometer (217-mile) front line extending from near the city of Zaporizhzhia to Russian-occupied Kherson. That area includes the Zaporizhzhia Nuclear Power Station which came under fire late Saturday. Each side accused the other of the attack. Ukraine’s nuclear power plant operator, Energoatom, said Russian shelling damaged three radiation monitors around the storage facility for spent nuclear fuels and that one worker was injured. Russian news agencies, citing the separatist-run administration of the plant, said Ukrainian forces fired those shells. Russian forces have occupied the power station for months. Russian soldiers there took shelter in bunkers before Saturday’s attack, according to Energoatom. Rafael Grossi, director general of the International Atomic Energy Agency, recently warned that the way the plant was being run and the fighting going on around it posed grave health and environmental threats. For the last four months of the war, Russia has concentrated on capturing the Donbas region of eastern Ukraine, where pro-Moscow separatists have controlled some territory as self-proclaimed republics for eight years. Russian forces have made gradual headway in the region while launching missile and rocket attacks to curtail the movements of Ukrainian fighters elsewhere. The Russians “are continuing to accumulate large quantities of military equipment” in a town across the Dnieper River from Russian-held Kherson, according to the Institute for the Study of War, a Washington think tank. Citing local Ukrainian officials, it said the preparations appeared designed to defend logistics routes to the city and establish defensive positions on the river’s left bank. Kherson came under Russian control early in the war and Ukrainian officials have vowed to retake it. It is just 227 kilometers (141 miles) from Odesa, home to Ukraine’s biggest port, so the conflict escalating there could have repercussions for the international grain deal. The city of Mykolaiv, a shipbuilding center that Russian forces bombard daily, is even closer to Odesa. The Mykolaiv region’s governor, Vitaliy Kim, said an industrial facility on the regional capital’s outskirts came under fire early Sunday. Over the past day, five civilians were killed by Russian and separatist firing on cities in the Donetsk region, the part of Donbas still under Ukrainian control, the regional governor, Serhiy Haidai, reported. He and Ukrainian government officials have repeatedly urged civilians to evacuate.
