All power reactor facility licensees and construction permit holders are requested to verify, unless verified to an equivalent degree within the last 12 months, that the seisaic analysis applies to the actual configura-tion of safety-related piping systems.
The safety-related piping includes Seismic Category I systems as defined by Regulatory Guide 1.29, " Seismic Design Classification," Revision 1, dated August 1, 1973 or as defined in the applicable FSAR.
The action items tuat follow apply to all safety-related pipitz 2-1/2-inches in diameter and greater and to seismic Category I ciping, re;3rdless of site which was cycamically analyzed bv ccmputer.
For older plants, wuere Seismic Category I require: eats did not exist at the tice of licensing, it must be shown that the actual configuration of ff/// safety-related systems, utilizing pioing 2-1/2 inches in diameter and treater, meets design require-cents.
Specifically, each licensee is requested to:
1.
Identify inspection eleceats to be used in verifying that the seismic analysis input infor:ation conforms to the actual configuration of safety-related systems. For each safety-related systea, submit a list of de sign documents, including title, identification number, revision, and date, which were sources of input information fo. the seismic analyses. Also submit a description of the seisaic analysis input info =ation which is contained in each document.
