The Nuclear Installations Inspectorate Site Inspector(s) made inspections to Devonport on the following dates during the quarter:
Specialist inspectors carried out inspection on the following dates during the quarter:
Some of the inspections were carried out with inspectors from the Ministry of Defence internal regulatory organisation, the Defence Nuclear Safety Regulator (DNSR), the Environment Agency and the Department for Transport.
The HSE-NII Deputy Chief Inspector responsible for regulating Defence sites visited the Devonport site on:
The HSE-NII Superintending Inspector responsible for inspecting Naval Bases and Dockyards visited the Devonport site on:
Inspections at Devonport Royal Dockyard Ltd are undertaken as part of the process for monitoring compliance with:
This entails monitoring licensee’s actions on the site in relation to incidents, operations, maintenance, projects, modifications, safety case changes and any other matters which may affect safety. The licensees/operators are required to make and implement adequate arrangements under the conditions attached to the licence in order to ensure legal compliance. Inspections seek to judge both the adequacy of these arrangements and their implementations. In this period routine inspections at DRDL covered:
In general the arrangements made and implemented by the site in response to safety requirements were deemed to be adequate in the areas inspected. However, where improvements were considered necessary, satisfactory commitments to address the issues were made, or are being sought from the licensee, and the site inspector(s) will monitor progress during future visits. Where necessary, formal regulatory enforcement action will be taken to ensure appropriate that remedial measures are implemented to reasonably practicable timescales.
NII, DNSR and the Environment Agency met with the senior management of DRDL to review safety performance since October 2006. We agreed that significant progress had been made by the company and the workforce over the year in a number of difficult areas. We were encouraged that the participative approach we’d recommended to address the safety culture improvements had been adopted, and by the involvement of all levels within the workforce and the extent of the involvement of the safety representatives. We welcomed the fact that DRDL has set even more challenging targets for safety performance over 2008 and taken a lead in developing safety performance indicators for its business.
NII and DNSR participated in the national level (Level 3 or Category A) emergency exercise “Short Sermon 2007” on 10th October 2007. This exercise, involving over 5000 people, tested the response of the staff of DRDL, HM Naval Base, Plymouth City Council, Local Authorities, other government department and agencies and the Emergency Services in Devon and Cornwall to an event at the site. It also tested the function of the on-site and off-site emergency response centres at Crownhill and at Middlemoor. Representatives were involved from NII, MoD and other agencies to provide advice to government in Whitehall.
NII concluded that while the outcome was considered to be a satisfactory demonstration of the Off-Site Emergency Plan for Devonport as required by the Radiation (Emergency Preparedness and Public Information) Regulations 2001, there was a need to make some improvements to the layout and operation of the off-site centre at Middlemoor, in particular to improve communications with the media. DNSR concluded that while there was an adequate demonstration of the Naval Base’s On-Site Emergency Plan there was a need to make some improvements to the forward command post.
Following the joint NII, DNSR and Environment Agency team inspection in August 2007 NII and EA held a follow-up meeting with DRDL to progress our findings. While we are pleased that the company has treated the matter as a priority, by appointing a full time Project Manager to tackle the waste management issue, we emphasised the need for DRDL to provide sustainable waste management solutions. We agreed we would now progress this matter on a quarterly basis. DRDL have also indicated that it is currently on track to complete the de-canting of radioactive waste accumulated in the Magnox Modified Flasks and the Resin Catch tanks into the new Resin Storage Vessels in advance of the date we specified.
Licensees are required to have arrangements to respond to non-routine matters and events. NII inspectors judge the adequacy of the licensee’s response including actions take to implement any necessary improvements. Matters of particular note considered during the current period include
Babcock International Group PLC announced on 10 May 2007 that the company had entered into an agreement with the current owners for the acquisition of Devonport Management Limited (DML). DML currently undertakes major Nuclear Submarine overhaul and refueling work for MoD at Devonport via its wholly owned subsidiary company Devonport Royal Dockyard Ltd (DRDL). DRDL is a site licence holder under the Nuclear Installations Act (1965) and certain prescribed activities carried out on the site are regulated by HSE-NII. The nuclear site licence places certain legal responsibilities on licensee organisations and, in particular, covers the requirement for the control of nuclear safety related matters through an appropriate body corporate with suitable leadership and management capabilities. When licensee organisational arrangements are subject to significant change, HSE-NII assesses the proposals paying particular attention to matters including the legal requirements to satisfy the site licence, leadership and management, organisational structures, intelligent customer capability, management responsibilities, nuclear safety competencies, control of work and sufficient relevant nuclear safety knowledge and experience.
HSE-NII has engaged with the relevant stakeholders to ensure that any proposed changes are properly conceived and executed such that high standards of nuclear safety performance continue to be secured at Devonport Royal Dockyard. The current position is that the licensee’s corporate and operational management structures remain unchanged and as such the nuclear safety related activities taking place at the site remain secure through the existing arrangements as regulated and inspected by HSE-NII. Recent interactions with DRDL senior management have taken place to offer advice from a regulatory perspective, relating experiences from similar purchases and from changes resulting from the establishment of NDA. Any future changes will be subjected to the site’s Management of Change process which requires that the effect on safety of any changes be assessed.
Under Health and Safety legislation NII Site Inspectors, and other HSE Inspectors, may issue formal documents to ensure compliance with regulatory requirements. Under nuclear site licence conditions HSE/NII issues regulatory documents, which either permission an activity or requires some form of action to be take; these are collectively termed Licence Instruments (LI). In addition Inspectors may issue enforcement notices to secure improvements in safety.
No Licence Instruments were issued to the licensee during this period.
The Nuclear Installations Site Inspector the Nuclear Installations Deputy Chief Inspector responsible for regulating Defence sites and the Director of Defence Safety Nuclear Regulator visited HM Naval Base Devonport on the following date during this quarter:
MoD activities, at HM Naval Base and Devonport Royal Dockyard, are inspected as part of the process of monitoring compliance with:
There were no routine inspections at HM Naval Base Devonport in the period covered.
HSE-NII has continued to monitor the MoD’s progress towards implementation of the strategy for dealing with laid up submarines at Devonport prior to the commencement of decommissioning. A number of submarines are now in storage at Devonport prior to commencement of the Defuel, De-equip and Lay-up Preparations (DDLP) process with further submarines expected to be taken out of service in the forthcoming period. To comply with Government policy, the MoD is required to de-fuel the redundant submarines, which have left operational service with the Royal Navy, as soon as reasonably practicable.
As previously reported to the LLC, the current DDLP facilities are coming to the end of their operational life and HSE-NII gave notice to the MoD and DRDL that no further DDLPs were to be carried out at Devonport until the installation of new facilities to bring about a low level defuelling route were complete. A number of the improvements are still to be delivered, including removal of the existing refueling crane and installation of a new reactor access house. However, detailed design and safety case development is now underway and we have provided comment on the Preliminary Safety Cases from DRDL for the safe removal of the 80Te crane and for the de-fuelling facility. We understand that the contracts have now been placed for most of the main elements of the programme and that funding for the work is established. As noted in Section 2.2 of the DRDL part of this LLC report, we are engaging with DRDL on a regular basis as this important project proceeds. The most recent MoD programme suggests that the new facilities can be completed by 2012 and we are pressing for improvements to this timescale. Until the new facilities are brought into service we are satisfied that, subject to satisfactory monitoring arrangements, the redundant submarines can be safely stored in a fuelled state at Devonport on an interim basis.
