These have been reviewed against the codes and methods currently described in the UFSAR. The information presented below represents the set of key codes used that do not currently reside in the UFSAR as well as their associated application. All of these codes/methods have been determined by Florida Power & Light to be appropriate for use in their respective applications.TableB-1Additional Codes and MethodsCODEAPPLICATIONANETHThe ANETH computer code is a one-dimensional code which was used for water level instability analysis. BULKTEMThis code was used to calculate the decay heat produced in the spent fuel pool by the recently off-loaded fuel. CHECWORKS-SFAThis code was used to determine Flow Accelerated Corrosion (FAC) predictions.CENTSThis code was used to perform Nuclear Steam Supply System (NSSS) modeling.CAFTAThe Computer Assisted Fault Tree Analysis (CAFTA) code was used in the modeling, development and maintenance of fault tree models.FLUENTGeneral Purpose Computational Fluid Dynamics (CFD) Program. HRA HRA Calculator is a software tool which was used to facilitate a standardized approach to human reliability analysis (HRA).LONGORThis code was used to quantify the decay heat produced by previously off-loaded fuel. LASERThis code was used to estimate flux depression in fuel. MAAPThe Modular Accident Analyses Program (MAAP) simulates plant response to severe accidents given a set of initiating events and operator actions. This code was used to support development of the St. Lucie Probabilistic Risk Analysis (PRA).MCNP5This code was used to perform criticality analysis. NSSSPlusThis code was used to generate Performance Capability Working Group (PCWG) design sheets.ORIGEN 2.1This code was used to support the determination of core inventory nuclides for dose calculations.ORIGEN2This code was used to support the determination of core inventory nuclides for decay heat calculations. PITRUST-PCPITRUST-PC is a computer program which was used to calculate local stress intensity at the junction of two cylindrical vessels.
