Aim of inspection
To provide regulatory confidence in relation to RP and compliance with Ionising Radiations Regulations 2017 (IRR’17) and LC18.
To asses the extent the Heysham 2 team is equipped to start making the transition from operation to defueling, deconstruction and ultimately decommissioning.
Subject(s) of inspection
- IRR17 – Rating: GREEN
- LC 18 – Radiological protection – Rating: GREEN
Key findings, inspector’s opinions and reasons for judgement made
The intervention focussed on the following:
- Summary of outage programmed work and its radiological implications.
- NGL Radiation Protection personnel organisation including level of support available.
- Radiation protection input to outage work planning including use of revised risk assessment arrangements.
- Operational dose management, i.e. day-to-day dose management and profiling during the outage
- Radiological event investigation and follow-up including response to leakages and spillages of radioactive material.
- Outage contractor selection, training, control, supervision, and competence.
- Radiation survey instrument maintenance and support arrangements including adequate monitoring equipment resources for the outage.
- Radioactive source management.
- Health Physics clearance arrangements.
- Revised requirements for IRR Regulation 7 (Consents)
The inspection found adequate arrangements were in place for the Unit 8 2023 Statutory Outage and it was judged an overall inspection rating of green was appropriate.
The inspection findings were presented to NGL at the close of the inspection.
I found adequate arrangements relating IRR 17 and LC18 requirements specifically with regard to operational doses management, contractor supervision and control, availability and maintenance of radiological protection survey instruments, radioactive source management and assessment of risk.
