Can the UK fast-track nuclear power without cutting corners on safety?

The UK’s nuclear regulator is being asked to consider radically
different designs on a scale and pace never before seen. That’s partly
why, as part of the deal, the two countries have agreed to accept each
other’s safety checks. The government claims this will “halve the time
for a nuclear project to be licensed”. The question is whether this can
be done as safely.

The US and UK take fundamentally different approaches to
nuclear regulation. The US’s Nuclear Regulation Commission (NRC) takes a
“prescriptive” approach. It sets detailed rules based on its own
research and enforces them directly. Like police setting speed limits, the
regulator decides the standards and then ensures nuclear operators meet
them. If an accident happens, operators can point to meeting every
requirement as evidence they followed the rules. They could even
legitimately blame the regulator.

The UK’s Office for Nuclear Regulation
(ONR) takes a “descriptive” approach. It sets broad standards but
leaves operators to prove how they will meet them. In road terms, the US
sets the speed limit and checks drivers obey it. The UK simply says cars
must stay on the road, leaving drivers to decide their own limits, prove
they’re safe, and take full responsibility if they crash. These two
approaches are driven to a large extent by the two country’s history and
make up of their nuclear industries. So while UK-US collaboration could
boost Britain’s nuclear industry and accelerate the path to low-carbon
energy, independence and transparency will be essential. Any perception of
corner cutting or transatlantic political interference could undermine
public trust and derail Britain’s nuclear ambitions.
