Licensee Action on Previous Inspection Findings Closed - Noncompliance - Item 324/325-77-18 Dosher Hospital plan was checked and found to be up-to-date during a subse-quent inspection (324/325-78-26). Dosher had been added to the accountobility log in the document control vault.

Closed - Noncompliance - Item 324/325-77-1 These requirements have changed since they were identified and this item is of no consequence now.

Closed - Noncompliance - Item 324/325-78-30-1 During this inspection period the procedure for cleaning and inspecting the spent fuel baskets prior to installation in the spent fuel pool was reviewed and found to be satisfactory. The initial cleaning will take place outside where any rust and foreign matter will be r,emoved and the baskets flushed 'with demineralized water.

The baskets will then be taken to the refueling ~ floor where they will again be fluched prior to being placed in the spent fuel pool.

Results of Inspection During the period of this inspection one apparent item of noncompliance was identified. No deviations were identified. A number of items of concern were observed and brought to the attention of the licensee for corrective action. The item of noncompliance and the items of concern along with the licensee's response are identified below: Noncompliance (50-324/79-37-1; 50-325/79-39-1) a.

Section 3.7.2.2 of the Technical Specifications r2 quires that where one or more of the diesel generator spray and/or sprinkler systems are inoperable a continuous fire watch with backup fire suppression equip-ment shall be established at the location within one hour. Contrary to this requirement, on October 16 the inspector found fire protection sprinkler and standpipe systems isolated to diesel generator bay No.

3.

The isolated systems were indicated by low pressure annunciator alarms for the systems. A followup investigation revealed that two deluge valves (DV-15 and DV-17) had been isolated for maintenance by the manual closing of three isolation valves. This action was taken without notifying operating personnel and having the system placed in a limiting condition for operation (LCO) and taking compensatory measures required by Technical Specifications. The LCO was established after the inspector found the condition, notified operating personnel

. . .

-5- ' . and they had investigated the cause of the annunicator alarm. This is an infraction. Similar items were brought to your attention in our letters dated May 14, 1979 and September 19, 1979.

b.

In the area of radiological control the following unsatisfactory conditions were noted: The 350 mr activity at the base of the auxiliary surge tank - adjacent to Reactor Building No. 2 requires that an area extending up to the road on two sides be roped off. Any increase in activity in thf4 tank could present a problem in access and radiation control in the area. The licensee has agreed to investigate to detemine what can be done to reduce the activity in the tank.

Excessive leakage from a steam leak was found on the floor of - Reactor Building No. 2 at the Sk' corner 20 foot level. This leakage was coming from an electrical connection box mounted on the wall of a room containing a leaking steam valve. The steam , was leaking through a conduit penetration into the connection box where it was condensing and leaking onto the floor. The licensee

took corrective _ action to contain the steam leak in the valve room and direct the leakage to appropriate drains in the room.

. In the area of maintenance the following unsatisfactory conditions c.

we'e noted: r - The right fire door on entering the diesel generator building at the south end is in urgent need of repair and would be difficult to close and contain a fire. The licensee management agreed to have maintenance performed to correct this, problen. A power cable and its conduit were pulled out of their connection box near the ceiling in Unit No. I cable spreading room. The cable was resting hard against the conduit coupling. This condition was brought to the attention of the operating personnel and they had the condition promptly repaired.

A large ESS-Div. 2 electrical connection box was found open at - the 20 ft.

level, SW corner in Reactor Building 2.

The cover was replaced after being brought to the attention of the operating personnel.

In Reactor Building 1 and 2 numerous covers were missing from - conduit openings. These findin3s were brought to the attention of management who agreed to investigate and have these covers replaced.

- Followiug earlier tains several minor washouts were found under the barrier fence adjacent to the switch yard and warehouse "H".

These findings were brought to the attention of security personnel, who had repairs made and drain pipes installed under the fence where flooding occurred.

In the area of operations the following unsatisfactory conditons were noted: Unit No. I south end scram discharge accumulator and drain piping - has broken hangers and damaged grout around the accumulator mounting. This damage apparently occurred during the Unit I reactor trip on October 19. The cause of this damage is currently being investigated by the licensee. No similar damage was observed at the North side accumulator for Unit 1.

- Several low pressure alarms for the fire protection system were observed to be energized at the panel in the Service Water Building.

This condition was brought to the attention of the operating supervisor to determine the cause for the energized annunciators.
