Independent Inspection
a.
Standby Gas Treatment Systems (SBGTS) declared inoperable Unit 1 (LER/R0 79-32/01T-0)
While the licensee was evaluating piping restraints in accordance with IE Bulletin 79-02, SBGTS A and B were declared inoperable.
Analyses indicated that piping restraints 1/2 - 75-04-164 and 165 had a safety factor of less than two. Reevaluation of the design of the restraints found the design safety factors to be less conservative than originally analyzed. The restraints were modi-fied to a safety factor of greater than four and the SBGTS was declared operable. The modification of the restraints appears to be in accordance with the drawings provided by Sargent & Lundy (S
& L). ITT Grinnel performed all work using station approved ITT Grinnell procedures and Field Planner (traveler). The inspector reviewed the weld inspection reports, weld maps, field planner and control reports and the as-built drawings.
(See RIII Report No. 50-254/79-24; 50-265/79-21, Paragraph 4).
b.
Safety Related Welding The inspector requested to review all Grinnell welding personnel qualifications including the 1 1/2" bent coupons for certifica-tion for welding on the torus, IE Bulletin 79-02 and IE Bulletin 79-14.
(1) Torus: All welding personnel certification coupons are radiographed.
(2)
IE Bulletin 79-14: No welding has been performed.
(3)
IE Bulletin 79-02; Five hangers and the plate washers were welded with fillet welds. The following personnel welded the hangers as indicated. The coupons and personnel certifica-tions were reviewed.
