Nuclear Free Local Authorities challenge UK government on New Cleo’s application for “justification” of its small nuclear “fast” reactor

2 In April 2024, the Nuclear Industry Association applied for
‘justification’ on behalf of NewCleo and its lead-cooled LFR-AS-200 fast
reactor to the Department for Environment, Food and Rural Affairs (DEFRA).
The department will support the future Secretary of State in their role as
the authority responsible for the ‘justification’ decision.

This was the first application for ‘justification’ for a so-called advanced modular
design in the UK. In its media release, NewCleo oozed confidence its
reactor design will meet with approval:

‘Justification’ is a regulatory
process which requires a Government decision before any new class or type
of practice involving ionising radiation can be introduced in the UK. A
justification decision is one of the required steps for the operation of a
new nuclear technology in the UK, but it is not a permit or licence that
allows a specific project to go ahead.

Instead, it is a generic decision
based on a high-level evaluation of the potential benefits and detriments
of the proposed new nuclear practice as a pre-cursor to future regulatory
processes.

The design failed the government’s readiness test to be entered
into the Generic Design Assessment (GDA). Even if justification is
forthcoming, with the design not selected for the GDA, it would surely have
to undergo an equally rigorous, but more uncertain, process.

Furthermore, the reactor operates using MOX (mixed uranium and plutonium reprocessed
fuel). Although, the press has previously reported NewCleo’s plan ‘to
take advantage of the UK’s massive stockpile of waste at Sellafield, where
it wanted to invest £2bn in a waste reprocessing factory and advanced
modular reactors that would have created around 500 jobs’, the government’s
recently published Civil Nuclear Roadmap makes clear that this material
will not be forthcoming: ‘We are providing clarity to vendors by
committing not to support the use of plutonium stored at Sellafield by
Advanced Nuclear Technologies whilst high hazard reduction activities are
prioritised at Sellafield’.

The other puzzle is X-Energy, which was given
£3.4m by government, but seemingly, like NewCleo, has been turned down for
consideration for a GDA. X-Energy have previously announced plans to deploy
its reactor design at a site in Hartlepool.

In response to the news, NFLA
Scotland Advisor Pete Roche and Emeritus Professor of Energy Policy at the
University of Greenwich Stephen Thomas put together a question set
exploring and challenging the justification and Generic Design processes.
This was sent by the NFLAs to Nuclear Minister Andrew Bowie. On receiving
the Minister’s response, a second letter with supplementary questions was
drafted and sent, and this has just been replied to by a senior Department
of Energy Security and Net Zero (DESNZ) official. The correspondence is
reproduced in this briefing for your information.
