To determine the adequacy of the dutyholders arrangements and adequacy of their implementation for compliance with LC15 – verifying against ONRs LC15 inspection guidance (ONR-INSP-GD-015)

  • LC15 – Periodic review (Rating: Green)

Key findings

The purpose of the inspection was to seek evidence of the compliance to the licensees arrangements for Licence Condition 15 (Periodic Review), and to verify that the arrangements and their implementation met Relevant Good Practice (as defined in ONRs inspection guide NS-INSP-GD-015 Rev 5).

I reviewed the site arrangements for LC15, including site schedule and key roles and accountabilities. I then followed this thread to inspect compliance for the A** Periodic Review of Safety (PRS) and examined the records produced for each stage of the PRS process.


I judge the the Licensee is compliant with Licence Condition 15, with only minor observations noted that would improve their arrangements.

Adequate complianceto the licensees arrangements was clearly demonstrated for the A** Periodic Review of Safety (PRS).

Therefore a GREEN rating has been given.
