The complexities of developing Accident Tolerant Fuel
07 March, 2024
Accident Tolerant Fuels are seen to offer both safety and economic benefits. Although some designs under consideration are evolutionary rather than revolutionary, it’s clear that progress is positive.

A foundation for advanced reactors
25 October, 2023
The business opportunities and deployment scenarios for advanced reactors are quite different from their larger light water cousins with a variety of sizes and scales to meet various output requirements. A new report from the US National Academy of Engineering explores the options.

Deep thought on disposal
03 November, 2022
Successfully creating a deep geological disposal site for high-level waste has long been a key challenge for the nuclear industry. Now, a series of breakthroughs seems to show light at the end of the tunnel

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.

Evaluating the safety of new fuel types. Part 2: accident & storage conditions
29 October, 2014
Determining the overall safety level for a new nuclear fuel is not trivial because it involves balancing a host of attributes in several operating scenarios. Currently, there is no focussed, peer-reviewed guidance to help perform such assessments. The work described here, based on a report by the World Nuclear Association’s Fuel Technology Working Group, is intended to be a starting point for formal safety assessment. By Julian Kelly

A passive heat removal retrofit for BWRs
15 November, 2013
One of the fundamental safety functions of nuclear power plants is residual heat removal. Nevertheless, during certain scenarios, like the station blackout, or loss of the ultimate heat sink, available active safety systems are often not sufficient to remove the decay heat. A retrofitted turbo-compressor system driven by a self-cooling Brayton cycle could provide autarky even in these beyond design basis accidents and extend the grace period of existing BWRs significantly.
