![]() ![]() “I knew from that day forward, it was just a matter of time,” the former president said of Putin launching an attack. ![]() I don’t agree with it and I do not support it and I’m not bound by it.’ “Putin said to me: ‘… I know Boris agreed to go along with you and John Major and Nato, but he never got it through the Duma. “Putin told me in 2011, three years before he took Crimea, that he did not agree with the agreement I made with Boris Yeltsin, that they would respect Ukraine’s territory if they gave up their nuclear weapons,” Clinton said on Thursday at a public discussion at 92nd Street Y, a Jewish cultural and community centre in New York. It was signed by Boris Yeltsin on behalf of Russia, Clinton for the US, and John Major on behalf of the UK, acting as a third guarantor nation. Clinton will be the only light water reactor currently producing cobalt-60.Įxelon Nuclear president Charles Pardee said: "We view this as an opportunity for Exelon to support an important medical technology that saves people's lives.Clinton said he had talked to the Russian president at the 2011 World Economic Forum in Davos, where Putin brought up the issue of the memorandum, under which Ukraine, Belarus and Kazakhstan agreed in 1994 to give up the nuclear arsenal they inherited on their territory from the Soviet Union, in return for assurances their sovereignty would be respected “within existing borders”. However, this elderly unit has been offline for essential repairs for many months and will not return until around March this year. In general, the supply situation for medical and industrial isotopes is shaky thanks to a reliance on this kind of ageing research reactor.Ĭlinton will join other power reactors that produce cobalt-60 around the world including: Embalse and Atucha 1 in Argentina, units 1 and 2 at Bruce B in Canada Qinshan 1 and 2 in China Wolsing 1 and 2 in South Korea and Leningrad 1 in Russia. All of these are pressurized heavy water reactors apart from Leningrad, which is an RBMK-design. ![]() The vast majority of the world's cobalt-60 supply - over 80% - has traditionally come from Canada's National Research Universal (NRU) reactor at Chalk River. Production should begin at Clinton's next scheduled outage, with the first cobalt products probably coming shortly after the next outage once the targets have been extracted and processed. After retrieval from the core, processing can extract the cobalt-60 for manufacture into a useful radiation source. It is produced by inserting a 'target' rod rich in non-radioactive cobalt-59 into a reactor core where free neutrons will be captured, turning cobalt-59 into cobalt-60. The radioactive isotope is used for a variety of medical and industrial purposes including cancer therapy, sterilisation of medical equipment, food irradiation and materials testing. Without specifying details of time or technology, GE-Hitachi announced that its technology is soon to be installed at the Clinton boiling water reactor during Clinton's current planned maintenance and refuelling outage in order to produce cobalt-60. The Clinton nuclear power plant in the USA will begin producing cobalt-60 for medical and industrial use, according to plant owner Exelon and GE-Hitachi Nuclear Energy. ![]()
