Hartlepool Power Station - SBI10 Emergency Equipment
- Site: Hartlepool
- IR number: 16-043
- Date: May 2016
- LC numbers: 10, 23, 24, 28
Purpose of intervention
The purpose of this intervention was to undertake compliance inspection activities at EDF Energy Nuclear Generation Limited's (NGL's) Hartlepool power station in line with the ONR's planned inspection programme contained in the Hartlepool Integrated Intervention Strategy (IIS) for 2016/17.
Interventions Carried Out by ONR
We performed a system based inspection (SBI) to confirm the implementation of safety claims made against the Station's emergency equipment. This inspection was undertaken by the ONR site inspector, with technical support provided by a control and instrumentation specialist. During this intervention we examined the Licence's compliance with the following licence conditions (LCs):
- LC10 - Training
- LC23 - Operating Rules
- LC24 - Operating Instructions
- LC28 - Examination, inspection, maintenance, and testing.
LC 34 (leakage and escape of radioactive materials) was not included in the SBI as we judged that it was not applicable to this system. Compliance with LC 27 was also not included because we did not consider that the emergency equipment sampled meets the definition of safety mechanisms devices and circuits (SMDC) contained within NS-INSP-GD-027.
The intervention was performed in line with ONR's guidance requirements (as described in our technical inspection guides) in the areas inspected.
Explanation of Judgement if Safety System Not Judged to be Adequate
The emergency equipment was judged to adequately meet the requirements of the facility's safety case.
Key Findings, Inspector's Opinions and Reasons for Judgements Made
- LC 10 (Training) - We examined the training programme for members of the incident response team and considered the training to be appropriate. We examined the training records for a sample of NGL staff claimed as fulfilling roles within the Station's emergency scheme. NGL provided records, via a computer database to demonstrate that staff training was up to date. We judge that the following inspection rating is appropriate for this licence condition: Green.
- LC 23 (Operating Rules) - We examined the Station's technical specifications relating to equipment provided for use in the event of an off-site nuclear emergency. Requirements for the availability of the principal items of emergency equipment were well defined, with a clear alignment between the Living Safety Case and the technical specifications. However, we observed that the availability of the Station's perimeter radiation monitoring system and metrological equipment is not currently managed via a technical specification and recommended NGL review its approach against ONR's latest guidance. Overall, we judge that the standard was generally consistent with relevant good practice and award the following inspection rating for this licence condition: Green.
- LC 24 (Operating Instructions) - We examined instructions for operation and maintenance of the Station's alternative indication centre (AIC), which is designed to enable essential parameters to be monitored in the event of unavailability of the central control room. The supplied documentation was of a good quality and followed the standard formatting and layout. The station personnel demonstrated a sound understanding of the equipment and its use. We judge that the following inspection rating is appropriate for this licence condition: Green.
- LC 28 (Examination, Inspection, Maintenance and Testing) - We examined the maintenance records for equipment installed in the AIC, the public address (PA) system and the perimeter radiation monitoring system. The licensee demonstrated that they have processes, procedures and records in place for the examination, inspection, maintenance and testing of these areas of plant. We observed that during maintenance activities there had been failures to meet acceptance criteria during some of the AIC functional tests. Given these maintenance results we placed an action on NGL to confirm that the indications in the AIC deliver their intended functionality. Overall, we judge that the following inspection rating is appropriate for this licence condition: Green.
Conclusion of Intervention
There are no findings from this inspection that could significantly undermine nuclear safety and no change is necessary to the planned interventions and inspections at Hartlepool as a result.
Section 4 of this report identifies the issues raised during this intervention. These issues will be entered onto the ONR Issues Database in order to monitor station's action to address them. ONR will monitor progress with addressing these issues through normal regulatory business.
