Followup of Inspector Identified Problems, Unresolved Items, and Open Items (Open) Open Item 10/75-14-01: The inspector verified through interviews that appropriate equipment has been installed. This item will be closed in the next inspection report following inspection of the modifications to verify adequacy and operability.
(Closed) Open Item 50-10/76-26-01:
Procedures and official site records were audited, and it was determined that retention of Unit I laundry Tank Level Charts is now required for five years, which exceeds the licensee l
committment of one year retention. Records retention through January 1980, were verified.
l (Closed) Open Item 50-10/77- -54: This item is closed as an open item as the concerns it addresses are covered by SEP Topic III-12 and IE
.
Bulletin No.79-01B. The requirements will be pursued when the present, j
indefinite plant shutdown for modifications is completed.
l l
(Closed) Unresolved Item 50-10/78-26-04: These model pressure switches
appear to be installed in Unit 1 only. The matter of their environmental qualification will be addressed along with IE Bulletin No.79-01B if and i
when 79-01B is implemented for Unit 1 (i.e., the decision is made to start up Unit 1).
-
(Closed) Unresolved Item 50-10/78-26-05:
Type 26R2-YY-45-05X Static
"0" Ring Pressure Switches appear to be installed in Unit 1 only.
!
Accordingly, they will be addressed as described in Unresolved Item l
50-10/78-26-04 above.

(Closed) Open Items 50-10/78-08-01, 50-237/78-07-01, and 50-109/78-07-01:
All concerns identified have been adequately addressed by the licensee when a new system for initiation, management, and closeout of work-requests was implemented in 1979 and early 1980. One area of inspector concern remaining open is the adequacy of the new work request system to-detect work requests which are issued to the organization responsible for completing them and then become delayed. The licensee concurs that, in
,
'some lower priority work requests, such delays could go undetected; and i
j is evaluating this potential program weakness at this time. This item will be tracked under Open Items 50-10/82-01-01, 50-237/82-02-01, and 50-249/82-02-01.
(Closed) Open Item 50-10/77-07-01: Two new Unit 1 area Radiation Monitor (ARM) Recorders have been installed. Their operability was checked by-the inspector and printing quality was excellent.
(Closed) Open Item 50-10/79-02-05: The inspector verified by observation that suitable structural bracing has been installed to the Unit I chimney.
door.
(Closed) Open Items 50-237/75-04-01, 50-249/75-04-01: The inspector toured the new IIALON CO, fire protection system to verify installation
~_. -and equipment operability, and found the equipment satisfactory. A review of the station documentation package for the modification indicated that adequate controls were used for procurement, installation, design, and shop testing of equipment. Records of onsite testing for correctness of installation and equipment operability were largely missing from the documentation. The licensee included a memorandum to file in the package to note this fact; however, the overall adequacy of the equipment (operability, etc.) has not been documented. The adequacy of the modification without complete documentation will be tracked under Open Items 50-237/82-02-02 and 50-249/82-02-02.
3.
Followup on Items of Noncompliance / Deviations (Closed) Open Items 50-237/81-09-02, 50-249/81-06-02: The inspector audited surveillance Procedure DFPP 4185-2 and scheduled procedure
,
'
implementation results for 4-13-81 and 10-16-31.
The adequacy of the current system for computer management of surveillanca requirements
,
'
which directs a copy of fire protection surveillances to the station fire marshall was reviewed. The licensee's corrective action appears adequate with the single exception of the fact that documentation of the 10-16-81 was not readily tracable because the work request for accomplishing the procedure (WR No. B0P16161) was held up for improve-I ments.to the procedure by electrical maintenance personnel. The procedure checklist also contained an error (extra, non-existant sensor)
which had not been documented or corrected for the past two surveillance.
,
The correction of this shortcoming will be followed under Open Items
,
'
50-10/82-01-01, 50-237/82-02-02, and 50-249/82-02-02 above.

t (Closed) Open Items 50-237/81-09-04 and 50-249/81-06-04:
Implementation of the 7-81 revision of Procedure DFPP 4114-5 which contains an inspection checklist which reflects installed equipment will adequately provide the required hydrostatic test records for fire hoses.
No items of noncompliance were identified.
4.
Independent Inspection Effort The inspector toured the Units 2 and 3 reactor building in the course of the inspection, including Unit 3 refueling activities, Standby Liquid Control System, LPCI Heat Exchanger Ultrasonic Tube Testing, CRD modifi-cation work, and Unit 2 Standby Liquid Control System, Reactor Water Cleanup System, CRD maintenance facilities, and Secondary Containment Provisions.
The inspector witnessed excessive amounts of debris (paper food wrappers, pieces of plastic covering, string and rope) floating on the water surface of the Unit 3 reactor cavity and dryer /separater storage pit during final I
flooding for refueling. The licensee took prompt action to remove the floating debris, and it is unlikely that adverse effects will result.
The inspector is concerned regarding the adequacy of controls to verify adequate reactor cavity and flooded storage area cleanliness during refueling operations. Controls for cleanliness and their effectiveness will be reviewed during a future inspection (50-237/82-02-3; 50-249/82-02-03).
The inspector noted that contractor personnel had opened one inside door in the double door reactor building rail car access. The door remained open for approximately four hours while the contractor worked on his equipment stored in the access pending removal from the reactor building.
While this condition existed, the exterior doors to the rail car access was degraded in that seather stripping and rail channel filler blocks were missing, allowing for a degraded condition of the scondary con-tainment which was not present during the surveillance test for secondary centainment. The licensee immediately closed the inner door, which returned the the containment to its "as tested" configuration.
Tests were also conducted to demonstrate that the secondary containment would still function, although all conservatism between the surveillance test results and the Technical Specification limit was lost. The licensee committed to evaluate his control for verifying secondary containment integrity and controlling usage of the rail car access. The results of this evaluation will be addressed in a future inspection report (50-237/82-02-04 and 50-249/82-02-94).
Immediate repairs to the exterior door were initiated by the licensee.
No items of noncompliance were identified.
5.
Exit Interview The inspector met with licensee representatives (denoted in Paragraph 1)
throughout the month and at the conclusion of the inspection on January 14, 1982 and summarized the scope and findings of the inspection activities.
The licensee acknowledged the findings documented herein.
