Three operators can manage plants with 12 NuScale reactors

AtomInfo.Ru, PUBLISHED 22.06.2020

The NuScale Power revised its shift composition for the NuScale small nuclear power plant.

The document submitted to the US Nuclear Regulatory Commission on June 11, 2020 states that the minimum shift composition for a complete nuclear power plant (12 modules with low-power NuScale reactors) can be formed from only three licensed operators.

Previously, the company believed that at least six operators should be in the shift, of which three were SRO levels. It was also assumed that the composition of the shift would not depend on the number of modules at the plant - that is, six operators should be in the shift even if only one NuScale module was installed at the station.

In the new minimum shift, there is one operator of the SRO level, acting as a control room supervisor, or shift supervisor with extended privileges.

Also, two operators are included in the shift, at least one of which must have an SRO license. A third operator only needs to have a less restrictive RO license.

NuScale Power also set an allowable time during which for some reason there may be less than three operators per shift. In such cases, no more than two hours are allotted to restore the composition of the shift.

Managing Nuclear Knowledge - A Forward Looking Story

Knowledge management came into existence as a new stream in the distinct area of information management at the beginning of the 90-ies. Many believe that the term "knowledge management" has been invented by the consulting community.

I think our members have understood that one of the biggest issues going forward is making sure that we have a new generation of young people that can take up the work of developing, deploying and operating nuclear facilities in the future.

Despite the benefits, small modular reactors also have disadvantages. In this paper we want to highlight and explore how SMRs challenge the existing nonproliferation regime. Finally, we draw conclusions from the analysis.
