Previous Insoection Item Ucdate (0 pen) Unresolved Item (289/77-09-02): The inspector reviewed
.
Revision 7 of Surveillance Procedure 1301-9.9; however, each coninent was not addressed and this item remains unresolved.
E (0 pen) Unresolved Item (289/77-09-03): The inspectcY reviewed the following documents associated with functional testing of hydraulic snubbers.
.
a.
GPU Service Corporation Memo, D. Bulgarelli to R. Barley, dated June 7,1977, subject - TMI Unit No.1 - Snubber Fluid Testing.
b.
Met-Ed Memo, R. Berley to R. Klingaman, dated August 8,1977, subject - Hydraulic Snubber Bleed Rates.
c.
Met-Ed Memo, R. Klingaman to J. O'Hanlon, dated December 21, 1977, subject - TMI-1., PR, Hydraulic Snubber Bleed Rates.
d.
Maintenance Procedure 1410-Y-34, Repair of Hydraulic Snubbers, Revision 0, November 7, 1976.
'
Items b. and c. above specify limits for lockup and bleed rates (except for minimum lockup velocity) for TMI-1; however, this criteria has not been incorporated into the licensee's procedure.
This item remains unresolved.

O (Closed) Unresolved Item (289/77-09-06): The inspector reviewed Surveillance Procedure 1300-lV25, Inservice Inspection of Piping Supports and Hangers fiot Welded to a Pressure Boundary, Revision 0, February 11, 1976, and had no further questions concerning this item.

Surveillance of Pice Succort and Restraint Svstems
-
a.
Record Review (1) Scoce The inspector reviewed the following records for conformance
'
with procedural and TS requirements:
.
(a) OPS-531, Reactor Building efain Steam Line Snubber Inspections for December,1977.
(b) Hydraulic Snubber Functional Testing Records from the April 1977 Outage (Procedure 1410-Y-34).
(c) Hydraulic Snubber Visual Inspection Records frcm March
.
to December 1977 (Procedure 1301-9.9).
(d)
Inservice Inspection of Piping Supports and Hangers G
for 1977 (Procedure 1300-lV25).
.
(2) Findinas (a)
Contrary to the requirements of Administrative Procedure 1010, Technical Specification Surveillance Program, and Surveillance Procedure 1301-9.9, Hydraulic Shock.and Sway Suppressors, the following items were identified by the inspector during a review of snubber visual inspection records.
-
On five different occasions, between March and-December 1977, data sheets were missing indicating that incomplete inspections were performed.
-
An Exception and Deficiency List was not executed on May 7,1977 following the completion of 1301-9.9E.
-
The corrective action specified for a snubber found
-
void cf hydraulic fluid was not folicwed on May 7, 1977 for snubber i:SE 96A.

The above items are examplet ;f failing to implement written procedures as requir s by T.S. 6.8.1 and
~
constitute an Item of Noncompliance (289/78-01-01).
(b) During the 1977 Cutage the licensee functionally tested 259 snubbers for operability. Many of these snubbers
-
were reinstalled without meeting the acceptance criteria of Procedure 1410-Y-34, Revision 0; however, the inspector noted that the licensee had addressed this problem in Quality Control Surveillance Report 77-109 and QC Nonconformance Reports 186 and 187.
The resolution of this problem involved a PORC review and a subsequent
,
engineering evaluation, which ccncluded that the non-conforming snubber settings would not detract from the snubber's ability to sustain seismic leadings. The inspector had no further questions on this item.
(c) The inspector reviewed the records from the 1977 in-service inspecticn of piping supports and hangers (Procedure 1300-lV25) and noted that those deficier~ 1s identified had been resolved or corrected.
The inspector also requested to review the results of the 1976 inspec-
.
tion, but the licensee was unable to locate the records during the period of this inspection-This item is
unresolved pending NRC review of the.1976 records from Procedure 1300-lV25.
(2G9/78-01-02)
b.
T.S. Table 3.16.1 The inspector attempted to verify that the licensee's Surveillance Procedure 1301-9.9, Hydraulic Shock and Sway Arrestors, Revision 7, and T.S. Table 3.16.1 included the same number of safety related snubbers. As a result of this audit, it was apparent that a dis-crepancy existed between the two lists and that the TS Table needed to be updated.
This item is unresolved pending a revision of TS Table 3.16.1 to include all safety-related snubbers and a verification that all of these snubbers are included in the licensee's visual surveillance precedure.

c.
Inservice Inscection Procedure Surveillance Procedure 1300-lV25, Inservice Inspection of Piping Supoorts and Hangers not Welded to a Pressure Soundary, Revision 0, February ll,1976, verifies for scring type hangers, snubbers and shcck abscrbers that the device is not at ei:ner end cf its

operating range.- Section XI, Category S-K-2, of tne ASME Ccde requires a verification of sucocet settincs for thsse types of supports and hangers.
This item is unresolvec pending revision of Procedure 1300-lV25 to meet the intent of requirement B-K-2 of Section "I of the ASME Code. (289/78-01-04)
d.
Hydraulic Fluid Controls The licensee's snubber surveillance program does rot include any controls over new hydraulic fluid which would prevent cross-contamination with old fluid during testing or a contamination with. foreign matter during storage of an unsealed container.
In addition, administrative controls do not exist which would ensure that th'e correct type of hydraulic fluid is added to a particular snubber.
This item is unresolved and is designated (289/78-01-05).
e.
Seal Material Procedure 1410-Y-34, Repair of Hydraulic Snubbers, Step 6.9.b, specifies the use of either ethylene propylene or cork end cap seals for snubber reservoirs.
Sin:e cork has been used for this
-
purpose, the inspector questioned the licensee on whether c_ork has been demonstrated compatable with the c, aerating envircnment for the snubbers affected. This information was not available
during the period of this inspection and is, unresolved.
(289/78-01-06)
f.
Observations The inspector examined selected main steam and emergency feed snubbers in the Intermediate Building while the plan't was at 100% power.
Several minor deficiencies were observed and noted to the licensee.
The inspector had no further questions in this area.
4.
Unresolved Items
-
Unresolved Items are matters about which more information is required in order to ascertain whether they are acceptable items, Items of Non-compliance or Deviations.
Unresolved Items disclosed during this inspection are discussed in paragraph 3 of this report.
