ANALYI1S OF PLANT STRUCTURES
nhe following information should be provided for analyses conducted to demon- strate compliance with Criteria III and IV of IZLVEG 0612, Section 5.1.
1. INITIAL CONlDITIONS/ASSL~r2'TIONS
Discuss the assumptions used in the analysis, including:
a. Weight of heavy load b. Impact area of load c. Drop height d. Drop location e. Assumptions regarding credit taken in the analysis for the action of impact limiters f. Thickness of walls or floor slabs impacted g. Assumptions regarding drag forces caused by th-:
environment h. Load combinations considered i. Material properties of steel and concrete
2. ;;.0DOF AorALLYSIS.
Provide the method of analysis used to demonstrate that sufficient load- carrying capability exists within the wall(s) or floor slab(s). Identify any computer codes employed, and provide a description of their capabilities.
If test data was e=ployed, provide it and describe its applicability.
3. CONCLUSION
Provide an evaluation comparing the results of this analysis vith Criteria III and IV of NJREG 0612, Section 5.1. Wnere safe-shutdown equipment has a ceiling or wall separating it fronan overhead handling system, provide an evaluation to demonstrate that postulated load drops do not penetrate the ceiling or cause secondary missiles that could prevent a safe-shutdown s~ste- fro= performing its safety function.
(3) A description of any Engineered Safety Feature filter system which includes infor- mation sufficient to demonstrate compliance with the guidelines of USNRC Regulatory Guide 1.52, "Design, Testing, and Maintenance Criteria for Engineered Safety Feature Atmos- phere Cleanup System Air Filtration and Absorption Units of Light-Water-Cooled Nuclear Power Plants."
(4) A discussion of any initial conditions (e.g., manual valves locked shut, containment airlocks or equipment hatches shut) necessary to ensure that releases will be terminated or mitigated upon Engineered Safety Feature actuation and the measures employed (i.e., Tech- nical Specification and administrative controls)
to ensure that these initial conditions are satisfied and that Engineered Safety Feature systems are operable prior to the load lift.
2. )ETHOD OF ANALYSIS
Discuss the method of analysis used to demonstrate that post-accident dose will be well within lOCFRlOO limits. In presenting methodology used in determining the radiological consequences, the following information should be provided.
a. A description of the mathematical or physical model employed.
b. An identification and summary of any computer program used in this analysis.
c. The consideration of uncertainties in calculational methods, equipment performance, instrunentation response characteristics, or other indeterminate effects taken into account in the evaluation of the results.
3. CONCLUSION
Provide an evaluation comparing the results of the analysis to Criterion I
of NUPREG 0612, Section 5.1. If the postulated heavy-load-drop accident analyzed bounds other postulated heavy-load drops, a list of these bounded heavy loads should be provided.
A-2 i
bounds other postulated heavy-load drops, a list of these bounded heavy loads should be provided.
