he rate of 67 energy release, hydrogen generation, and cladding oxidation from the metal/water reaction should be calculated using the Baker-Just equation (Reference. 2745). For non-LOCA applications, other correlations may 68 be used if justified. DRAFT Rev. 3 - April 1996 4.2-14 (h) Fission Product Inventory: To meet the guidelines of Regulatory Guides 1.3, 1.4, 1.25 and 1.77 (Refs. 6, 28-30) as they relate to fission product 69 release, the available radioactive fission product inventory in fuel rods (i.e., the gap inventory) is presently specified by the assumptions in those Regulatory Guides. These assumptions should be used until improved calculational methods are approved by CPBSRXB (see Reference. 70 71 3115). One such method currently approved is presented in ANS 5.4 (Reference 28) and provides an acceptable analytical model for calculating the release of volatile fission products from oxide fuel pellets during normal steady-state conditions. When used with nuclide yields, this model will give the inventory of volatile fission products that could be available for release from the fuel rod if the cladding were breached.72 D. Testing, Inspection, and Surveillance Plans Plans must be reviewed for each plant for testing and inspection of new fuel and for monitoring and surveillance of irradiated fuel. 1. Testing and Inspection of New Fuel Testing and inspection plans for new fuel should include verification of cladding integrity, fuel system dimensions, fuel enrichment, burnable poison concentration, and absorber composition. Details of the manufacturer's testing and inspection programs should be documented in quality control reports, which should be referenced and summarized in the Safety Analysis Report. The program for onsite inspection of new fuel and control assemblies after they have been delivered to the plant should also be described. Where the overall testing and inspection programs are essentially the same as for previously approved plants, a
