Pre-Submittal Meeting for St. Lucie Unit 2 Spent Fuel Pool Criticality Analyses April 30, 2018
Purpose
- Describe the planned scope and methodology for the proposed St. Lucie Unit 2 Spent Fuel Pool Criticality Analysis License Amendment Request
- Partial criticality analysis for cask pit rack only
- Seek feedback from NRC staff 2
Agenda
- Technical Specification Changes
Current Condition - SFP Criticality Analysis
- Safety Evaluation for St. Lucie Unit 2 Spent Fuel Pool Criticality Analysis LAR was issued in September 2012 (ML12263A224) o Analysis was performed in support of Extended Power Uprate project
- Analysis performed with CASMO-4 and MCNP5

Current Condition - Technical Specifications
- Technical Specifications contains allowable storage patterns for each region 6
Current Condition - Fuel Storage Limitations
- Storage patterns included in criticality analysis were developed based on estimates for future storage needs under EPU conditions
- Current storage patterns are not optimal o Reliance on empty cells limits capacity o Not aligned with fuel storage needs under EPU conditions 7
Current Condition - Options
- NextEra Energy considered various options to improve storage capacity o new cask pit rack o additional dry storage casks o full criticality re-analysis partial criticality analysis 8
Agenda
- Technical Specification Changes
New Criticality Analysis
- Our plan is to perform a partial criticality analysis that will fully replace the parts of the current analysis addressing the cask pit rack only o Follows precedent from Duane Arnold criticality analysis
- All other parts of current analysis remain the same o No changes to current Technical Specifications for Regions 1 and 2
- Partial criticality analysis will be performed in-house 10
New Criticality Analysis
- Partial criticality analysis will follow o NRC Guidance DSS-ISG-2010-01, Staff Guidance Regarding the Nuclear Criticality Safety Analysis for Spent Fuel Pools o NEI 12-16, Guidance for Performing Criticality Analyses of Fuel Storage at Light-Water Reactor Power Plants
- Codes will be PARAGON 1.2.0b and MCNP6.1 with ENDF/B-VII.1 cross section library
- As for current analysis, the partial analysis will ensure that keff 0.95 with the pool flooded with borated water, and keff 1.0 with unborated water, with 95% confidence / 95% probability 11
New Criticality Analysis
- No significant changes or factors to address o No change in fuel design o No change in operating conditions o No change in rack design o No Boraflex
- Will revalidate all analysis parameters o Reactor depletion parameters o Boral areal density o Axial burnup shape 12
New Criticality Analysis
- Will re-perform all analyses for cask pit rack o Design basis assembly o Tolerances o Uncertainties o Accidents o Code validation
- No interfaces with Region 1 nor Region 2 will need to be addressed 13
New Criticality Analysis
- New storage patterns have been preliminarily developed o 3 out of 4 fresh assemblies, crediting integral burnable absorber o 4 out of 4 irradiated assemblies with one CEA, burnup credit o 3 out of 4 irradiated assemblies, burnup credit o 1 fresh and 2 irradiated assemblies To address interface between first two patterns FBA 1 1 FBA FBA 1 1 1
FBA 1 14
New Criticality Analysis
- For the fresh fuel category crediting integral burnable absorber, it would require n number of rods at a minimum concentration o If condition is not met, fresh assembly would then be stored in current 2 out of 4 configuration in Region 1 15
New Criticality Analysis - Implementation
- As done today for all NextEra Energy PWRs, PISCES code will be used as supplementary verification tool o After move plans are prepared and reviewed
- PISCES code o Determines fuel category for all fuel assemblies & non-fuel items o Tracks all inserts and panels (credited and non-credited) o Evaluates configuration/proposed moves against Technical Specification requirements o Provides summary & graphical output files 16
Agenda
- Technical Specification Changes
Technical Specification Changes
- Technical Specification Figures 5.6-4, Allowable Cask Pit Storage Rack Patterns, will be replaced o New storage patterns, definitions and notes will be added
- Technical Specification Table 5.6-1, Minimum Burnup Coefficients, will be modified o Values for fuel type 8 will be modified o New fuel types will be added o Values for fuel types 1-7 will NOT be modified 18
Technical Specification Changes 19
Technical Specification Changes 20
Agenda
- Technical Specification Changes
Closing Summary
- Schedule of LAR submittal o Plan to submit in December 2018
Backup Slides 23
Current Condition - Fuel Storage Needs
- Fresh fuel stored in 2 out of 4 configuration in R1 or CPR
- Once burnt fuel stored in 3 out of 4 configuration in CPR
- Twice burnt fuel stored in 3 out of 4 configuration in any of the three regions 24
Current Condition - Cask Pit Rack 25
