i SUMMARY Scope:
This routine, unannounced inspection was- conducted in the areas of licensee -
actions on previous inspection findings', maintenance / housekeeping, reportable occurrences, thermal sleeve weld examination, and Inservice Inspection (ISI)
including the eddy current examination of the Unit 2 steam ' generator tubin The inspection included a review of the Unit 2 ISI plan -for this . outage; reviews of nondestructive examination (NDE) procedures;Dobservations of in progress NDE examinations; reviews of NDE personnel qualifications; reviews of 4 NDE equipment calibration and material ' certification documentation; ~ and, a !
review of completed NDE examination data.' i Results: ;
This inspection indicated that ISI nondestructive examinations were being conducted adequatel The NDE personnel conducting the examinations appeared well qualifie The inspector noted . weaknesses celated to the following:
-
the inability to retrieve documents - Unit 2 Ten (*ar ISI Plan- (Paragraph 3.e.(1)(b)) and .
radiographic film (Paragraph 3.e.(3)); present mo'nitoring program for special !

(b) The licensee was unable to provide- the inspector.with a-copy of the Unit.2 Ten Year ISI Plan, or any evidence =that one ever existed.- The licensee did however, provide the i inspector with a copy of the 40 month period plans.for~each 1 of the three 40. month : periods in thel first . ten year-. 1 interval and an audit ,to assure that all the: necessary

examinations had been accomplished or scheduled. to ' be ; l accomplished. at schedule and. frequency , consistent with j Section XI of the ASME B & PV Code. The Unit 2 Ten Year l ISI Plan for the second ten year interval is in preparatio now and is scheduled' to be issued prior to the- end of the 1 fiat interval in December 199 (c) The licensee has established a' program to evaluate quality ,
record microfilm film quality to detect potential film or '
image degradation, accomplished by an annual examination.of a one percent sample of the total microfilm on' hand. 'The licensee does not.have a similar program howeverffor other' "

Alt .ough, in the areas where the inspector made these observations no damage was i noted, damage from personnel climbing on installed equipment could exist elsewhere. The inspector's concern.in this matter is: equipment important to safety could be damaged and thus be ,
unable to perform its safety function when needed. The licensee ;
indicated that the prohibition on climbing on installed !

The next day the licensee was able to locate some of the missing film , but not all. They indicated that they would reradiograph those segments for which the film could not be located. The above is indicative of carelessness and lack of attention to detai (4) Relative to the steam generator examinations the licensee visually identified leak indications (boron deposits, dry, wet, or dripping) at tube plugs in all three steam generators. EC examination indicated that the plugs were cracked. All the leaking plugs were from the same heat (Ht. No. 6323) of inconel 600 material. The' licensee removed all hot leg Ht. No 6323 Inconel 600 plugs and replaced-them with Inconel 690 plugs (S/G A 17, S/G B 18 & S/G C 45). There are a-total of 181 Ht. N ;
6323 Inconel 600 plugs in the three Unit 1 steam generators. In addition, as a result of the EC examination of steam generator tubing, the licensee plugged a total of 100 additional tubes (S/G A 33, S/G B 23, & S/G C 44). ;

Relative to the inspection above, the inspector noted one side of double door S7128, the access to the plant cafeteria, located in the main hallway on the ground floor, of the administration building, one of- the highest

traffic areas in the plant,. marked " FIRE DOOR KEEP CLOSED" was blocked open, due to an inoperative fusible lin This link would normally hold :
1 the door open when the room temperature is below the fuse temperature, i This condition has existed from before the, start of this inspection to October 3,1990 when the fusible link was repaired, as the result of this inspector's identificatio When questioned about this condition the ,
licensee indicated that this door is part of the fire boundary as defined
! by Appendix A, to Branch Technical Paper 9.51 'The licensee was unable to
'
determine how long the fusible link door closer' had been inoperative causing the door to be blocked open. The above is a clear indication of complacency and lack of attention to detail on the part of all the ;
licensee personnel who pass that door on a daily basi During this inspection, the relative safety significance of- the above i discussed circumstances could not be determined, as well as whether those circumstances are in violation of regulatory requirement Pending additional NRC review in this ~erea, this matter wa: identified as e unresolved item 50-338, 339/90-26-01: " Inoperative Fire Door".

In the areas examined, no violations or deviations were identifie > ReportableOccurrences(92700)
The LERs listed below were reviewed to determine if the information provided met NRC requirement The determinations included the verification of compliance with TS and regulatory requirements, and addressed the adequacy of the event description, the corrective actions

This LER was associated with a design error. that had the potential to over stress anchored service water system pipe supports and cause a failure of the service water system piping during a design basis acciden The inspector reviewed documentation provided by the licensee to verify the completeness of the corrective action. The. inspector determined that the licensee's corrective actions have been adequate to prevent recurrence of this event.

6 Thermal Sleeve Weld Examination In 1982 VEPC0 found some thermal sleeve retaining welds in the reactor coolant system were cracked. The affected sleeves were removed. The remaining sleeves were committed to be monitored with temporary loose parts monitoring system until the sleeves were removed. The temporary loose parts monitoring system has failed and will be removed. The licensee has committed, by VEPC0 letter dated June 15, 1990, to monitor the remaining sleeves by radiography every third outage until all the sleeves are remove The inspector reviewed the radiographs made during.this outage for the four remaining sleeves in Unit 2. The. licensee to date has not provided a programmatic means to assure that the remaining sleeves will be inspected cs comitted. The licensee indicated that the radiographic monitoring of l the thermal sletves will be iRluded as an augmented examination in the respective ISI plan .

The inspector descrit,; the areas inspected and discussed in detail the inspection results listeJ belo Although reviewed during this inspection, proprietary informat;on is not i contained in this repor The licensee objected to the inclusion, in this report, of the of the unresolved item related to the fire door and it's ignored sign, which is discussed in paragraph 4 abo"e.
