1) What codes do you use to verify / check a vendor-developed core loading pattern? N/A, in house core designs are used

2) Do you use a tool to assess the risk of cladding failure due to Pellet Cladding Interaction (PCI)? If so, which one? Core design reviews the Westinghouse(fuel vendor) calculations provided and verifies the applicable acceptance criteria are met.

3) What software tools do you use to measure power distribution limits? (e.g. Beacon, Incore) Incore instruments/PCS data input into Simulate/Cecor

4) Do you use any other tools or codes for core performance monitoring? If so, what are they, and what do you use them for? We have some qualified spreadsheets that perform the reactivity anomaly calculation, etc
