This inspection, at the RRMPOL licensed Nuclear Fuel Production Plant site at Derby, was undertaken to judge whether RRMPOL was ready to adopt the new safety case for the Chemical Plant in order for the ONR Nominated Site Inspector to release a regulatory hold-point.
On the 4 and 5 August the Nominated Site Inspector undertook the readiness inspection in relation to the updated safety case for the Chemical Plant.
Not applicable during this intervention.
The Site Inspector was presented with the RRMPOL Internal Regulation function’s own readiness activities. Based on the information provided the Site Inspector judged that this was a comprehensive and thorough activity. The Site Inspector then inspected the Chemical Plant and associated documentation to confirm the adequacy of implementation of a representative sample of the safety case requirements. Evidence was seen that RRMPOL are in an advanced stage of implementing the new safety case. The inspection included reviewing a number of the operating instructions to ensure that operating rules are properly implemented. The inspection identified some findings regarding the clarity of working instructions to implement Operating Rules.
Based on the inspection findings the Site Inspector considers that it is appropriate to release the regulatory hold-point associated with adoption of the Chemical Plant safety case. The remaining implementation activities will be subject to the ongoing RRMPOL Internal Regulation function concurrence activities.
The Site Inspector concludes that for the Chemical Plant, RRMPOL has adequately implemented their arrangements under LC 24, with some opportunities for further minor improvements identified, which RRMPOL has committed to addressing.
