REPPIR-19 has significantly changed the risk assessment upon which the scale of off-site plans are based, updated the requirements of both off-site and on-site plans, moved responsibilities (mainly from the regulator to the local authorities) and changed consultation, cooperation and training expectations. There is a great deal of work required to get on-site and off-site plans up to standard and, in particular there is a greater need for records to be kept of consultations, discussions and agreements. A summary of the application of REPPIR-19 across the UK can be found at Katmal.co.uk/reppir2019progress.html.

Off-site plans

REPPIR-19 has made some important differences to the expectations placed on off-site emergency plans (Regulation 11). Of note is the need to have covered outline planning for most nuclear sites and the transition to recovery for all nuclear sites. The revised regulations have also confused the situation with regard to Emergency Exposures and Reference Levels of Dose. There is a significant amount of work to do to make REPPIR-01 off-site plans meet the requirements of REPPIR-19.

Katmal has helped a local authority revise their off-site plan and audit it against REPPIR-19.

The good news is that Katmal Limited has helped local authorities audit their existing plans against the need of REPPIR-19, recommended revising to get the plan up to standard and revised plans. The other good news is that the costs can be charged to the operator.
