Pipe Support Verification Program The NRC issued the Show Cause Order, dated March 13, 1979, addressing potential piping support deficiencies in safety-related systems.
The purpose of this inspection was to monitor the licensee's activi.
ties to verify the "as built" configuration of pipe supports in the systems identified for reanalysis.
To accomplish this verification, the licensee divided the plant into 168 areas consisting of 103 piping isometric drawings designated M5K's.
Each accessible pipe support within the individual MSK was measured to establish its relative location and its conformance with the design drawing.
At the time of this inspection, the licensee had completed 150 of 168 areas, 85 of 103 MSK's, and drafted 41 of the 85 drawing changes.
The NRC inspector selected 15 pipe supports in 3 systems completed by the licensee for verification of the installed configuration.
The inspection consisted of visual examination for condition and compariron of selected dimensional characteristic with those speci-fied by the applicable drawings.
Deviations from the specified drawing dimensions were checked against the data compiled by the licensee to confirm the effectiveness of the licensee's program.
The following supports were examined:
Support System Number Remarks RHR H10-24 Item No. 1, 1/2" x 9" x 2' plate,
' corner missing RHR H10-25 Item Ncs. 4 and 5, specifies 1-3/8" x 1/2" x 8",
actual 1-7/8" x 1/2" x 14"; section C-C is not constructed per drawing.

RHR H10-41 Base plate is not grouted.

Item 6 specifies 18-1/2", actual 17-3/4"; assembly of box frame not per drawing.
CS H14-42 Base plate bolts loose; trunnion to basc plate veld exhibits undercut, porosity, undersize, and nonuniformity; 1/4" gap between base plate and wall.
CS H14-42A Item 9 is bent; Item 8 to 6 gap is 1/4"; specified is 1/16"; base plate is pulled away from wall.
CLCW H15-2 Two pipes supported by hanger, only
,r one shcwn; base plate to wall has 3/8" shim.
CLCW H15-5 Box frame members specify " weld all-around", members not fully welded.
Comparison of the foregoing data with that compiled by the licensee showed acceptable correlation. This matter is considered unresolved pending evaluation and dicposition of the foregoing deficiencies (333/79-06-01).
During the examination of the core spray piping system supports, H14-42 and H14-42A, it appears from the bent components, loose bolts, hangers pulled away from the wall, and crushed insulatiou that the piping had experienced a dynamic transient such as a water hammer. A review of past event reports and plant records by the licensee could not establish if this condition had been identified

-3-and evaluated previously. The licensee issued Work Requests Nos.
1425 and 1426 describing the condition. This matter is considered unresolved pending evaluation, disposition, and correction of the conditions (333/79-06-02).
The licensee stated that, due to the similar nature of Bulletin 79-04, Incorrect Weights for Velan Swing Check Valves, this bulletin
-
would be addressed concurrently with the pipe stress analysis.

Pipe Support Base Plate Designs Using Concrete Expansion Anchor Bolts (Bulletin 79-02)
The licensee has developed a preliminary procedure for testing the adequacy of installed concrete expansion anchor bolts.
The licensee was evaluating the feasibility of the procedure at the time of this inspection. The licensee stated that the testing phase for inacces-sible pipe supports would be accomplished prior to the facility returning to power operation.
4.
Longitudinal Weld Defects in ASME SA-312 Type 304 Stainless Steel Pipe (Bulletin 79-03)
Bulletin 79-03 identified longitudinal welded stainless steel pipe manufactured by the Youngstown Welding and Engineering Company as possibly containing defects.
The licensee performed a document review to verify that the aforementioned manufactured pipe was not used at the Fitzpatrick facility.
The NRC inspector reviewed the original pipe construction specifica-tion, AP-23 Specification for Furnishing, Delivering, and Erection of Piping, and determined that SA-312 Type 304 piping was not specified for use at Fitzpatrick.
He reviewed 192 pipe material certifications and verified that Youngstown Welding and Eagineering Company was not a supplier of pipe to the Fitzpatrick facility.
The inspector had no further questions concerning this matter.
5.
Unresolved Items Unresolved items are items about which nore information is required to ascertain whether they are acceptable items, items of noncompli-ance, or deviations.
Two unresolved items disclosed during this inspection are discussed in Section 2.
6.
Exit Interview The inspector met with the licensee representatives (denoted in Section 1) on May 4, 1979.
The inspector summarized the purpcse and scope of the inspection and findings.
