Operational Assessment of Critical Safety Parameter Monitoring
Findings and Lessons Learned.
Abstract:
This paper summarizes the findings and recommendations from an operational assessment of the Critical Safety Parameter monitoring facilities and practices proposed for Pickering B. The Critical Safety Parameters consist of a small set of plant parameters that can be used to assess the degree of plant safety challenge in power control, fuel cooling and containment integrity.
The assessment was undertaken to:
• Confirm and improve the effectiveness of Critical Safety Parameter monitoring practice at Pickering B,
• Address regulatory concerns associated with the proposed operational introduction of a Critical Safety Parameter display at Pickering B, and
• Pilot test a proposed approach to integrating human factors in station design changes.
The paper begins by describing the role of Critical Safety Parameter monitoring and restoration practice in support of plant emergency response and the basis for the assessment. The balance of the paper outlines the assessment objectives and approaches applied, reviews the key assessment findings, and discusses the lessons learned.
