UFSAR CHAPTER 15 ACCIDENT ANALYSIS
- General Accident Analysis, Core Source Term, and Radiological Dose Consequences
- Most accidents, as well as source term, dose consequences, and design transients see negligible changes from placing 16 higher enriched LTA fuel rods into a core of 50,952 active rods.
- Avg enrichment of the core is only increased 0.0003% by 4 LTAs.
- Avg core enrichment remains ~ 4.4 - 4.6%.
8
UFSAR CHAPTER 15 ACCIDENT ANALYSIS - Continued
-This increase in enrichment is not a significant driver of increased source term, dose consequences, or cooling requirements, and is within the bounding assumptions and safety margins of the existing analyses which conservatively assume 5.00% enrichment for establishing source term and dose consequences.

LOCA ACCIDENT ANALYSES

- Applicationandsupplementsdesignate thatwhileLTAsmaybeplacedincertain limitingcorelocations,theLTAsmayonly beutilizedinsuchlocationswhichare nonlimitingwithrespecttothecontrol rodejectionanalysis.
13
Neutronics
- SNC uses the PARAGON lattice physics code and NEXUS for neutronics calculations.
- There is no significant deviation in the neutron flux spectrum.
Therefore, there is reasonable assurance that these codes will adequately model the LTAs.
- PARAGON and NEXUS have been compared to the PARAGON2 code, which has been shown to be acceptable at enrichments greater than 5 wt% U-235.
- PARAGON2 has been shown to be acceptable to analyze the neutronic performance of new, unapproved fuel designs,
- No proposed changes to the nuclear design process.
14
CORE PHYSICS
- Fluxspectrumwillcontinuetobedominatedbycoresident fuel.
- Peakingfactorsremainlessthanwhatisassumedinthe UFSAR.
- DifferencesbetweenLTAsandcoresidentfuelaremodeled explicitly.
