- denotes those present at the exit meeting held on February 2,1990 2.0 Follow-up of Previous Inspection Findings
(Update) Unresolved item (50-352/87-31-02) Diesel Lube 011 Exhaust Leak Fire Hazard.
This item pertains to lube oil leakage from sn exhaust flange which results in heavy smoking from its burning on exhaust piping.
The licensee routinely experiences smoke alanns during diesel operations from the diesel oil leakage. The inspector was concerned that substantial oil leakage in the hot manifold area could cause a fire.
The licensee has approved a modification (5914-2) for Unit 2 Diesel engines to reduce the amount of oil that leaks from exh ust flanges and to limit the amount of excess oil which accumulates in the exhau;t line. The modification involves
_
the installation of an air valve in the diesel air start line, between the air
-
r-manifold and the pressure regulator for the main bearing lube oil booster.
The
'"'
valve will provide a means of isolating air to the main bearing oil booster when it is desireable to use the air system to rotate the diesel engine and clear it of excess oil. The manufacturer, Colt Industries, concurs with this modification. This modification has been approved by the Plant Operations Review Committee for Unit 2 diesels but has not yet been approved for Unit I diesel :

.
.
p
To allow rotating of the engine, the diesel generator will have to be declared INOPERABLE since the engine emergency stop will be manually depressed. The engine will then be slowly rotated with the diesel air system.
Returning the diesel generator to OPERABLE status will require strict control of the air valve position to ensure availability of air to the main bearing oil booster and correct positoning of the fuel rack. Therefore, pending NRC review of the completed installation of the modification and of the administrative controls associated with returning the diesel to service, this item will remain open.
3.0 Fire protection / Prevention Program (64704)
The inspector reviewed documents in the following areas of the program to verify that the licensee had developed and implemented adequate procedures consistent with the Final Safety Analysis Report (FSAR), Fire Protection Evaluation Report, and licensee commitments.

Removal is required of all wastes, debris, rags, oil spills or other
combustible materials resulting from work activities at the end of the job or at the end of each work shift, whichever is sooner;
All wood used in safety-related areas is reautred to be treated with
!
,
flame retardent; Periodic inspections are specified for accumulation of combustibles;
Housekeeping is required to be properly maintained in areas containing
safety-related equipment and components; r
Requirements exist for special authorization (work permit) for acti-
vities involving welding, cutting, grinding, open flame or other ignition sources and that they are properly safeguarded in areas containing safety-related equipment and components *
Prohibition on smoking exists in safety-related areas, except where
" smoking permitted" areas had been specifically designated by plant management; Fire brigade organization and qualifications of brigado members are
delineated;
'
Fire reporting instructions for genera,1 plant personnel are developed;
Periodic audits are required to be conducted on the entire fire
protection program; and, Fire protection / prevention program is included in the i tcensee's QA
program.
The review of these documents did not identify any procedure wednesses.
,
Dis:ussions with fire protection engineers indicated that they we.'e knowledgeable of the fire protection program and fire systems. The above areas were reviewed with inspection observations described below.
3.2 Equipment Inspection and Tests The. inspector reviewed selected documents to determine if the licensee had developed adequate procedures which established inspection and testing require-ments for the plant fire protection equipment. The inspector also reviewed inspection / test records to verify compliance with Technical Specift:ations and with established procedures. Documents reviewed are listed below.

During the review of test records, the inspector noted that test abnormalities and deficiencies were adequately reviewed and resolved by retest, when necessary.
During this inspection the inspector witnessed the testing of the diesel driven
,
,
fire pump in accordance with procedures.
The inspector noted that alarms
!
associated with high cooling water temperature were appropriately resolved.
This included declaring the diesel fire pump INOPERABLE and cleaning out appropriate strainers which appeared to reduce the available cooling water flow.
.
The inspector commented to the fire protection angineers that it may be worthwhile including the strainers in the licensee's per' odic maintenance program.
The inspector also reviewed the maintenance t'r m t list to determine the amount of fire protection equipment that is inoperable.
1he fi a protection equipment that requires maintenance has only a minor impace on pla-t safety.
