NFLA Policy Briefing 313: Correspondence with the Nuclear Regulator over AGR Extensions

We note the recent EDF press release stating that a decision to life-extend
all four remaining AGR stations has been taken by EDF with Heysham 1 and
Hartlepool extended to 2027 and Heysham 2 and Torness extended to 2030.

The ONR site says for Heysham 1 and Hartlepool that: ‘EDF have recently
communicated their decision [March 2023] to extend the generating lifetime
of the station to March 2026, subject to an adequate demonstration of
safety.’ But there is no further information on whether an adequate
demonstration of safety has been submitted and assessed, and no mention of
extension to 2027.

For the other two AGR stations, no mention is made on
the ONR site of EDF’s intention to life-extend the plants, and the EDF and
the ONR sites give a forecast end of generation as 2028 for the two AGRs.
On your questions regarding EDF’s press release, the results of the EDF
inspections indicated that the graphite cores remained within the
limitations of the current safety cases.

The results of these inspections
have not been published by EDF. These inspections informed EDF’s commercial
judgement to pursue lifetime extensions; it is not within ONR’s scope of
regulation to consider the commercial viability of the life extension of
these reactors.

It is likely that EDF will require new safety cases to
justify operation to the specified end of generation dates and these will
be considered by ONR as part of normal regulatory activities.
