Level 4 intervention to assess the continuing adequacy of NNB GenCo's organisational capability

Executive summary

Purpose of intervention

This intervention was part of a series of interventions by the Office for Nuclear Regulation (ONR), the purpose of which is to assess the continuing adequacy of NNB Generation Company (NNB GenCo) Limited's organisational capability.

Interventions Carried Out by ONR

The specific topics addressed in this intervention were:

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

I found that NNB GenCo was on track to review and revise its resourcing strategy, nuclear baseline and vulnerability assessment by October 2014. The first part of this is an update to projected resource requirements (numbers and skills) over the project lifecycle. After this, NNB GenCo will define how these resource requirements will be met via various 'pipelines' (recruitment, secondment etc). The update to the nuclear baseline aligns with this but looks at a shorter timeframe (ie to 'J0' - first nuclear island concrete). I conveyed to NNB GenCo ONR's expectation that, in its revised resourcing strategy, NNB GenCo strikes a suitable balance between EDF staff and contractors to demonstrate that NNB GenCo remains in control of its activities.

I found that NNB GenCo has completed an interim post-implementation review of the changes associated with the financial realignment of the HPC project in 2013. NNB GenCo has recognised that these changes introduced higher workloads in certain parts of the organisation, which is consistent with ONR's observations in certain workstreams. I encouraged NNB GenCo to capture the learning from this so that it can be built into future resource planning and organisational changes.

I observed that in certain functions within NNB GenCo embedded contractors currently account for approximately 50% of posts. NNB GenCo recognised this as a potential vulnerability which it intends to address through updates to its organisational capability metrics and resourcing strategy. NNB GenCo also recognised the need to reconcile its organisational capability metrics against the specific observations on resourcing and workload issues made by ONR through its various interventions.

Conclusion of Intervention

NNB GenCo is progressing the update to its resourcing strategy, nuclear baseline and vulnerability assessment in line with plans presented to ONR at the start of 2014. NNB GenCo has recognised the higher workloads and other vulnerabilities which have arisen (in part) from the financial realignment of the HPC project in 2013. It will take account of these in the ongoing updates to its organisational capability metrics and resourcing strategy.
