New polls show substantial support for nuclear energy
Sixty percent of respondents in a recent national survey favored the use of nuclear energy, with only 25 percent opposing its use. While the latest Bisconti Research poll focuses on nuclear power and electricity generation, its findings on public interest in climate change and using a spectrum of sources to meet energy needs are consistent with a recent Pew Research Center poll on a broad set of energy policy and climate change topics. The approaches the two online surveys took to measuring public opinion on nuclear energy yielded different numbers but found some common ground.

ITER cryogenic system is in its final design phase to be constructed at Cadarache, South of France. It shall use the most advanced cryogenic technologies developed for accelerators projects adapted and optimized to fulfil the requirements and constraints of a large fusion installation.A refrigeration capacity equivalent to 65 kW at 4.5 K is planned for the cooling of superconducting magnets, their HTS current leads and small users. It also includes the cooldown of the cryogenic pumps and their re-cooling after regeneration. A 1300 kW nitrogen plant provides cooling power for the thermal shields. The key design requirement is the capability to cope with large pulsed heat loads deposited in the magnets due to magnetic field variations and neutron production from the fusion reaction.The cryogenic distribution system is based on the design of a complex and compact transfer line system and several cryogenic distribution and feed boxes.After recalling the basic features we shall present the status of the design and the main magnet interfaces and key design requirements.
