<p>On 11 March 2011, the Fukushima-Daiichi nuclear power station (FDNPS) suffered major damage after the magnitude 9.0 great east-Japan earthquake and subsequent tsunami. It was the largest civilian nuclear accident since the <a href="https://css.unscear.org/unscear/en/areas-of-work/chernobyl.html">Chernobyl accident</a> in 1986. Radioactive material was released from the damaged plant and tens of thousands of people were evacuated.</p> <p>The main findings of the <a href="https://css.unscear.org/unscear/en/publications/2013_1.html">UNSCEAR 2013 Report</a> titled "Levels and effects of radiation exposure due to the nuclear accident after the 2011 great east-Japan earthquake and tsunami" were reported to the <a href="https://css.unscear.org/unscear/en/ga/general-assembly.html">General Assembly</a> in October 2013 <a href="https://undocs.org/en/A/68/46">(A/68/46)</a>, and the <a href="/unscear/en/publications/2013_1.html">report</a> was published in April 2014, along with the supporting scientific data and evaluation.</p>

Cryogenic technology will be extensively used at ITER to create and maintain low-temperature conditions for the magnet, vacuum pumping and some diagnostics systems.The ITER magnets will be cooled with supercritical helium at 4 K (-269 °C) in order to operate at the high magnetic fields necessary for the confinement and stabilization of the plasma. They will be surrounded by a large cryostat and an actively-cooled thermal shield with a forced flow of helium at 80 K. Additionally, large cryoabsorption panels cooled by supercritical helium (4 K) will be used to achieve the high pumping rates and vacuum levels in the cryostat and torus.A cryoplant on the ITER platform will produce the required cooling power, and distribute it through a complex system of cryolines and cold boxes that make up the cryodistribution system.The cryoplant is composed of helium and nitrogen refrigerators combined with a 80 K helium loop. Storage and recovery of the helium inventory (25 tonnes) is provided in warm and cold (4 K and 80 K) gaseous helium tanks. Three helium refrigerators supply the required cooling power via an interconnection box providing the interface to the cryodistribution system. Two nitrogen refrigerators provide cooling power for the thermal shields and the 80 K pre-cooling of the helium refrigerators. The ITER cryogenic system will be capable of providing cooling power at three different temperature levels: 4 K, 50 K and 80 K.Helium exists in a liquid form only at extremely low temperatures. Baths with liquid helium (LHe) at 4.5 K and at 4.2 K (down to 3.7 K) provide the cold source to extract and transfer heat from the components to the cryoplant. Forced-flow supercritical helium (SHe) circulates through ITER components to remove heat and provides the required low temperature environment.The distribution of cooling power is accomplished through cryodistribution boxes with helium circulating pumps for the cooling of the magnets and cryopumps, and a complex system of cryog
