MSPI stands for Mitigating Systems Performance Index.

MSPI stands for Mitigating Systems Performance Index.

• A. Mitigating Systems Performance Index
• B. Major Safety Performance Indicator
• C. Monitoring Safety Performance Index
• D. Maximum Safety Performance Index

Answer: (A)

Mitigating Systems Performance Index measures how reliably the systems designed to lessen the consequences of initiating events actually perform when needed. These mitigating systems are the equipment that acts to reduce the impact on the plant, helping to prevent core damage if something goes wrong. MSPI is the established term used in safety monitoring and oversight to track the availability and readiness of these systems. The other option expansions don’t match the terminology used in industry safety tracking, so they aren’t correct.
