Licensee Action on Previous Inspection Findings (Open) Inspector Follow Item (311/78-43-01):
The licensee currently is meetin'g his commitments and requirements for the preservice inspection of pipe supports and restraints. However, further review will be required to determine the acceptability of the licensee 1s insulation removal practices during future inservice inspections. This item is reclassified as an Inspector Follow Ite *
(Open) Unresolved Item (311/78-43-02):
The licensee provided the inspector with a Public Service Electric and Gas Company (PSE&GC)
letter to R. Griffith from K. Bass dated November 22, 1978, address-ing insufficient thread engagement and hydraulic fluid leakage on steam generator (S/G) snubbers. Three S/G snubbers with insufficient thread engagement have been identified. Hydraulic connections will be retightened and piping flushed after the Hot Functional Tes The licensee has not yet corrected the extending bolt on the valve assembly on S/G -23Z snubber. This item therefore remains unresolve (Closed) Unresolved Item (311/78-19-03):
The licensee provided the inspector with Deficiency Reports indicating that diagrams and drawings are being revised to reflect actual rated loads and that replacement of a few existing snubbers with correct snubbers of appropriate load ratings has taken plac The licensee stated that a review of all snubber load ratings with actual loads anti-cipated has taken place and all discrepancies have been resolve This item is close (Closed) Unresolved Item (311/78-29-06):
The licensee stated that the Outstanding Items List has been used to adequately control reassembly of safety related hangers and supports after initial installatio The inspector made a thorough tour of the plant for unassembled hangers or pipe supports and identified non A further review of the Outstanding Items List indicated that it was being used to track and resolve previously unassembled and then reassembled hangers that required further adjustment and inspectio Based on the use of the Outstanding Items List this item is considered close.
Pipe Supports and Hangers a.. General An inspection was conducted of a random sample of pipe supports, restraints, guides, and snubbers at normal operating temperature on the following systems: Safety Injection, Chemical Volume and Control, Residual Heat Removal, and Pressure Relie The piping supports were verified against design drawings and 11 Reactor Coolant System Thermal Expansion Hot Functional Test Procedure" SUP 50.1 for correct thermal growt The inspector
verified that interference due**to thermal expansion was not occurring at normal operating temperature and that hot settings of snubbers, restraints, and hangers conformed with design drawing specification The inspector reviewed completed data for SUP 50.1 and verified that the licensee had conducted a satisfactory review, evalua-tion, and disposition of problems encountered at normal operating temperature. Accuracy of SUP 50.l data was verified by inde-pendent measurements on previously selected guides, hangers, and snubber Discrepancy Control The inspector questioned the method for controlling problems encountered that had a long term effect or which could not be resolved during the hot functional testing. The licensee stated that these items would be placed on the "Outstanding Items List 11 which will ensure that these problems are resolve A review of the Outstanding Items List indicated that this method of tracking problems was in fact presently being used for the control of hangers and support problems of a long term nature~ The inspector had no further questions at this tim.
Piping System Vibration The inspector* reviewed PSE&GC Procedure "Vibratory Analysis of No. 23 Reciprocating Charging Pump Piping" dated November 16, 1978, and the results of water hammer data taken during the 11Pressurizer Relief and Safety Valve Slowdown Test" (PR-072778).
The inspector had no further questions on the procedures or data at this tim.
Exit Interview At the inspection 1s end the inspectors held a meeting (see Detail 1 for attendees) to discuss the inspection scope and findings.
