Review of Licensee Event Reports (92700) and Nonconforming Operations
Reports (71707)
a.
Licensee. Event Reports (LERs) were reviewed for potential generic impact,.to detect' trends, and to determine whether corrective actions appeared appropriate.
Events that were reported immediately were reviewed as they occurred to determine if the TS were satisfied.
LERs were reviewed in accordance with the current NRC Enforcement Policy.
-
(1) (0 pen) LER 89-01: This LER reported that solenoid air valve:,
for four containment isolation valves were undersized with resp,ect[tomaximumoperatingpressureandm'aypreventthevalves i
from performing their safety function.
This matter was the subject of a violation (302/89-01-01) and is discussed in detail
,
'
in NRC Inspection Report 50-302/89-01.
The licensee plans to is, sue,.a supplement to this report in March 1989. The LER will remain"bpen pending review of the supplemental report.
(2) (0 pen) LER 89-02:
This LER reported the failure to update the Inse.rvice Inspection Pump and Valve Program for recently

The inspector reviewed Nonconforming -Operations Reports (NCORs) to verify the following: TS are complied with, corrective actions as identified in the reports or during subsequent reviews have been accomplished or are being' pursued for completion, ' generic items are identified and reported as required by 10 CFR Part 21, and items.are reported as required by TS.
All NCORs were reviewed in accordance with the current NBC.Enfpree-ment Policy.
(1) NCOR ' 89-15 reported that ' TS 3.4.4.c does n'ot require a suf-ficient number of pressurizer heaters needed to maintain a steam bubble in the pressurizer foilowing a loss of off site power.
-
The current TS requires at least 126kw of heater load be-available from the emergency power - source 'o maintain the pressurizer bubble. The licensee discovered during correspon-
.dence with. Babcock and Wilcox in response to the Technical
.
Specification Improvement Program (TSIF) that convection losses from the pressurizer are greater than 126 KW (approximately 132 KW).- The licensee has performed surveillance tests to ensure that greater than 132 KW of heaters can be supplied from the o
emergency power source and plans to submit a Technical Specifi-cation Change Request (TSCR) to upgrade the existing TS.
IFI (302/89-03-01):
Follow the licensee's activities to change TS 3.4.4.c to require an adequate number of pressurizer heaters.

Installation and Testing of Modifications (37828)
Installation of new or modified systems were reviewed to verify that the
.
changes were reviewed and. approved in accordance with 10 CFR 50.59, that the changes. welre ' performed in accordan'ce with technically adequate and approved pr66eduVes, that subsequent testing and test results met acceptance criteria or deviations were resolved-in an acceptable manner, and that appropriate facility procedures were revised as necessary.
This review inc.luded/se.lected observations of modifications and/or testing in progress.

,
Within a discipline group, drawings are divided into series, cusing,,,the second and third digits, such as:
.
206-XXX Electrical, One Line Diagrams
'
'
314-XXX Electrical, Cable Tray and Supports In the Control Room the 302 series, Mechanical Flow Diagrams, and the 201-061 thru 071 series, Distribution Panel Arrangements, are maintained.
These are maintained as up to date, as built blue line drawings.
'
In the Techt ical Support Center (TSC) a complete set of aperture cards and selected blue line drawings (302 series) are maintained.
A review of a sample of drawings in the Control Room and in the TSC revealed that the drawings were readable and of the latest revision. The potential exists for the Control Room to have a later revision than the TSC since. the TSC. drawings are of lower priority than the control room
. drawings.
If this were to occur then the TSC would have an interim drawing showing the change.
' '
For temporary modif'ications (T-Mar), no reference is made on the drawing.
An interim drawing is produced and a. copy placed with the drawing in.the control room.
Since the base drawing does not reference the T-MAR the potential exists for loss of the interim drawing without the operator l
being aware.of!the. loss.. This was discussed with licensee personnel and they are eva10af.ing further actions.
For Control Room drawings there is no specific number of changes that triggers a drawing revision. since the drawing must be revised prior to turnover of the system to operations followingtt)emo;d1fication.
,
In the event that a drawing discrepancy is noted, a Field Problem Report i
(FPR) would be written to the engineering department.
In a licensee
!
evaluation,of;the Crystal River - 3 drawing system initiated in July.of 1986 and reported in March of 1987, the comment was made that using the FPR was burderisotne! to the preparer and.dispositroner.
This report recommended.that,a " Drawing Discrepancy Report" might be a better vehicle.
i than the FPL.. To.*dat6 the FPR is still used.
i There is no specified turnaround time for drawing discrepancy FPR's.
No periodic audit of the accuracy of control room or TSC drawings was apparent.

and data completed on August 5, 1988 and November 8, 1988.
'
While reviewing procedure SP-344A to verify implementation of the licensee's IST program, the inspector noticed that spent fuel pump discharge check valves (SFV-26/27) were not being tested in the closed position.
.The testing of emergency feedwater system check valves to
'
verify ~ p' roper performance of safety functions in the closed position is
!
already the subject of an unresolved item * (302/88-31-01).
Since the
!
licensee is presently evaluating all safety system check valves to determine safety functions and proper testing, the unresolved item will be
'
expanded to include all safety systems.
