Inside the Candu MCR simulator
12 December, 2018
The Candu MCR simulator continues to be a much-used asset providing valuable hours to experiment, test ideas without real-world risk and learn from simulated malfunctions that would be rare in operational control rooms. Susan Creber and Robert Leger give an overview of the system.
Bringing Beznau 1 back online
21 June, 2018
Beznau 1 recently returned to service after the Swiss regulator confirmed aluminium oxide inclusions in the reactor pressure vessel do not affect the unit’s safety case. Michael Dost looks back at over three years of testing and analyses that helped get the world’s oldest PWR back into operation.
Molten salt reactors spark interest in USA and Denmark
06 April, 2018
Terrestrial Energy USA and Energy Northwest on 31 March signed a memorandum of understanding on possible siting, construction and operation of an Integral Molten Salt Reactor (IMSR) at the Idaho National Laboratory (INL) in southeastern Idaho. Terrestrial Energy USA, part of Terrestrial Energy Inc, is developing the IMSR for deployment in the US market. Terrestrial's IMSR integrates the primary reactor components, including the graphite moderator, into a sealed and replaceable reactor core. The reactor, which can produce 400MWt (190MWe), is a modular design for factory fabrication. Terrestrial hopes the IMSR can be brought to market in the 2020s and began a feasibility study in 2017 to site a commercial IMSR at Canadian Nuclear Laboratories' Chalk River site. The reactor design has already completed the first phase of the Canadian Nuclear Regulatory Commission's vendor design review. It announced in January that it plans to submit an application for design certification or for a construction permit to the US Nuclear Regulatory Commission by October 2019.
