Enclosed for your review are the Helium Circulator and Secondary Coolant System submittals, which make up the remainder of the Category I inservice inspection and testing program submittals for the Fort St. Vrain High Temperature Gas-Cooled Reactor. These submittals contain draft modifications to the FSV Technical Specification Surveillance Requirements, along with an evaluation of the proposed requirements, as in the previous submittals.

Enclosures (1) and (3) contain the draft revisions of the FSV Technical Specification Surveillance Requirements for the Helium Circulators and Secondary Coolant System, respectively, which include the following sections:

March 31,1980 Page 2 Enclosure (1)

SR 5.2.17 - Helium Circulator Pelton Wheels, Surveillanca SR 5.2.18 - Helium Circulators, Surveillance SR 5.2.19 - IACM Diesel-Driven Pumps, Surveillance SR 5.2.27 - Helium Shutoff Valves, Surveillance Enclosure (3)

SR 5.3.1 - Steam / Water Dump System, Surveillance SR 5.3.2 - Main and Hot Reheat Steam Stop Check Valves, Surveillance SR 5.3.3 - Bypass and Pressure Relief Valves, Surveillance SR 5.3.4 - Safe Shutdown Cooling Valves, Surveillance SR 5.3.9 - Safety Valves, Surveillance SR 5.3.10- Secondary Coolant System Instrumentation, Surveillance The revised portions are identified by vertical lines on the right-hand-side of the pages.

Enclosures (2) and (4) contain an evaluation of the additional or modified surveillance requirements which are the result of PSC's review of the current surveillance requirements for the Fort St. Vrain Helium Circulators and Secondary Coolant System. The systematic approach used to develop these requirements is explained further in the first pages of the review.

These four enclosures complete PSC's review of the surveillance requirements for Category I systems and equipment. PSC is proceeding to review the inservice inspection and testing surveillance requirements for the Category II systems and equipment identified in Reference 1. Prior to establishing a schedule for completion of the Category II review, PSC requests that the flRC complete its review of the Category I submittals and provide PSC with comments on the adequacy and acceptability of the approach being utilized by PSC to establish detailed inservice inspection and testing program requirements.

Also attached (Enclosure (5) is the information requested by the flRC at a meeting held on August 20,1979 (see Reference 2) concerning Fort St. l Vrain equipment built to ASME codes, and concerning inspections and tests being performed that are not currently included in the Fort St.
