Hartlepool Power Station –  Planned Compliance Inspections

Executive summary

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 2015/16.

Interventions Carried Out by ONR

Assisted by an ONR Specialist Inspector, I undertook an intervention to evaluate arrangements for the production and assessment of documentation to justify the safety of operations. The intervention involved planned compliance inspections against the following Licence Conditions (LCs):

I attended the intentions meeting for the 2016 periodic shutdown of Hartlepool Power Station, Unit 2. The purpose of this meeting was to confirm the scope of work which NGL intend to perform during the next periodic shutdown of Unit 2.  I also attended the site’s Health Environment and Safety Advisory Committee and held meetings with members of the site’s management team.

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

Not applicable, no system based inspections undertaken during this intervention.

Key Findings, Inspector's Opinions and Reasons for Judgements Made

In respect to LC12, I considered that NGL’s framework for the development and evaluation of competence for nuclear safety engineers (whose duties include production of safety documentation) was an example of good practice. This warrants an IIS rating of 2 (good).

Based on our sample inspection of LC14 arrangements, we concluded that safety documentation produced via the safety case anomalies process, is undertaken to a good standard, in accordance with due process.  We found that some delays had occurred to routine work to review safety case documentation. I am satisfied that this observation is of limited safety significance and I have placed an action on NGL to confirm how they will accelerate this work. Overall a judge that the standard of compliance warrants an IIS rating of 3 (adequate).

Our engagement in respect to the 2016 Unit 2 periodic shutdown provided ONR appropriate clarity in relation to NGL’s proposed scope of work and warrants an IIS rating of 3 (adequate).

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.

I have raised an ONR Issue to manage my findings in relation to our observations in relation to licence condition 14.
