Risk-Informed Decision-making Regional Action Plan Julio Lara, Director, Division of Reactor Projects, Region III
2 ADVANCE RIDM Develop risk thinkers and leaders at all levels and establish path to support sustained focus on RIT and RIDM Recommend new IMC 1245 Qualification Card - Risk and Reliability Inspector Rotational assignment to work with senior reactor analysts Risk-informed thinking workshops Risk-informed thinking certification Recommend Revision of MD 8.3 Deterministic Questions Enhance 71111.20, Refueling and Other Outage Activities, implementation Dedicated, focused inspection effort on Outage Risk Management Presence in Outage Control Center and Work Control Center Risk Mitigation Actions Configuration Controls
MD 8.3 Deterministic Questions What if ?
a.
Involved operations that exceeded, or were not included in the design bases of the facility b.
Involved a major deficiency in design, construction, or operation having potential generic safety implications. Involved an infrequent or rare initiating event (e.g., loss of offsite power, steam generator tube rupture, partial loss of DC power, loss of instrument air, LOCA, fire, flood)?
c.
Led to a significant loss of integrity of the fuel, primary coolant pressure boundary, or primary containment boundary of a nuclear reactor.
Involved an initiating event and functional impacts to mitigating systems or barrier integrity SSCs?
c.
Led to the loss of a safety function or multiple failures in systems used to mitigate an actual event.
d.
Involved possible adverse generic implications.
e.
Involved significant unexpected system interactions.
f.
Involved repetitive failures or events involving safety-related equipment or deficiencies in operations.
g.
Involved human errors that caused an initiating event or impacted the function of risk important SSCs questions or concerns pertaining to licensee operational performance.
