This intervention was to undertake inspection and other activities as part of a series of planned interventions supporting ONR’s DRDL Intervention strategy.
ONR’s Devonport Lead Site Inspector held a planned meeting with DRDL’s Nuclear Compliance Manager and Cross Site Plant Manager to discuss a potential change to the Licensed Site boundary. ONR and DNSR met with DRDL’s Emergency Planning Manager to discuss progress with the production of DRDL’s on-site Capability Map self-assessment. ONR attended a meeting to discuss progress on the revision to DRDL’s Safety Performance Indicators (SPIs) as part of the Nuclear Safety Improvement Programme (NSIP). ONR, DNSR, and EA attended the Through Life Management Programme (TLMP) Level 3 Regulatory Interface Forum (RIF). ONR and DNSR also observed the 2015 Level 1 Joint Emergency Exercise which is the annual demonstration of the DRDL and HM Naval Base emergency arrangements as required under Licence and Authorisation Condition 11.
The TLMP Level 3 RIF provides the opportunity for the Devonport regulators (ONR, DNSR and EA) to engage with the Devonport DRDL and MoD nuclear facilities project planning managers. DRDL provided ONR with updates on the submarine programme requirements of the Devonport facilities, the Laid-Up Submarines (LUSM) project, and DRDL’s asset strategy approach for critical items. The Regulators welcomed this engagement but proposed a further Level 3 RIF for early in 2016 because of the rapid development of these projects.
A team of ONR and DNSR inspectors observed Joint Emergency Exercise 2015 (JEX15). The exercise aim was to demonstrate and test the Nuclear Emergency Arrangements in response to a Devonport Site Accident on the Devonport Site outside normal working hours. Overall, ONR and DNSR judged that the exercise had been an adequate demonstration of the Devonport emergency arrangements but confirmed that a redemonstration of specific areas will be required in early 2016.
No additional regulatory concerns were identified as a result of this intervention and future engagement will continue as detailed in the DRDL Intervention Strategy.
