1 PURPOSE NRC Question 130.42 requested data be provided to justify the simplified analysis method referenced in FSAR section 3.7.3.8.
This simplified method is used to define supporting systems for 2-inch and under or cold piping systems of larger sizes.
REFEPENCES 1.
" Question / Answer Index," Final Safety Analysis Report, Question No. 130.42.
2.
" Analytical Procedures for Piping," Final Safety Analysis Report, Section 3.7.3.8.
DISCUSSION A simplified analysis method was prepared in order to provide instructions fcr supporting piping systems to which a formal computer analysis was not to be applied. The subject NRC question requested that tables comparing the results of detailed dynamic analysis of various piping systems to the results of the simplified method be provided.
Piping system configurations associated with the tabularized data were also petitioned. The data presented herein has been prepared in conjunction with this request.
The simplified analysis method is based on the application of maximum allowable spans plus associated support reactions and system stresses. This pertinent information is generated through the use of a simplified floor response spectrum dynamic analysis.
Input consisted of applicable pipe properties, material code allowables and response spectrum data. Output from the solution of the dynamic system equations includes reaction data and stresses for numerous span lengths.
Maximum allowable span lengths were then determined on the basis of a stress and/or natural frequency criteria. For stress application purposes, an OBE seismic stress of 6000 psi was utilized.
In the case of the latter, the conditions 1
1 applied were that the fundamental frequencies would be higher than those associated with the dominating peak of the applicable floor response spectrum.
The comparative assessment provided herein addresses four different piping systems.
An index to this analysis is presented in Table 1.0.
Table 2.0 provides stress /
frequency data for the subject analysis. A comparison of support design loads to the analyzed loads is listed in Tables 3.0 through 3.3.
SUMMARY
The simplified analysis method utilized to define support systems for 2" and under or cold piping systems of larger sizes is referenced in FSAR Section 3.7.3.8.
The tabularized data presented herein as requested by NRC question 130.42 addresses both stati.: and dynamic loading on supports. A direct comparison by load type is provided. When the different types of applied loads are combined in accordance with code requirements, the loads generated for the design of supports in conjunction with the simplified method, exceed those produced through the formal analysis. Results based on the application of this simplified method are conservative and therefore acceptable fot design purposes.
