INDIAN POINT ENERGY CENTER DECOMMISSIONING OVERSIGHT BOARD Dr y Spent Fuel Storage Cask Basics

Cask Design and Evaluation

Cutaway of spent fuel storage cask shows spent fuel assemblies surrounded by steel and thick concrete shielding Casks come in dif ferent sizes

A ging Management

What materials aging mechanisms can affect the safety functions of storage casks?

Materials + Environments => aging mechanisms and effects Time-Limited Aging Analysis (TLAA): Time-based calculations Aging Management Program (AMP): Activities to detect or prevent aging effects and perform corrective actions

NUREG-2214 ML9214A111 High Burnup Fuel

NRC guidance on storage and transportation of high burnup fuel published in NUREG-2224 (ML20191A321)

The Department of Energys high burnup fuel research program will evaluate the effects of drying operations and storage Regional Inspection Program - Routine Inspections

NRC Inspections

- Ensure ISFSI meets regulations during construction and operation

- Cover pad design and construction

- Observe dry runs without spent fuel

- Monitor cask loading

- Routine monitoring Regional Inspection Program - D r y Ru n s

Dry Run training exercise must include:

Loading, Closure/ Welding, Handling, and movement to ISFSI pad.

Spent Fuel Security

ISFSI security key features:

Armed security officers, intrusion detection, alarm assessment, and response Defense against design basis attacks During decommissioning, the security posture has a strong focus on ISFSI.

As long as fuel is on site, security is maintained Emergency Planning

Emergency planning is required for ISFSIs at reactor sites and at stand-alone facilities The emergency plan includes emergency actions level Emergency plans could include both nuclear and non-nuclear emergencies ISFSI at Indian Point

ISFSIs continue to be inspected for safety and security ISFSIs remain robust and are secured around the clock 24/7 NRC staff will continue to monitor aging management inspections Questions?
