2. Licensee Action on Previous Inspection Findings .

(0 pen) Inspector Follow Up Item (IR 50-267/76-13): Records of plant

operating cycles. While the licensee appears to be maintaining

records of each cycle, fonnal administrative controls for maintaining

records has not been established. Moreover, the licensee considers

that scrams from power levels less than 100 percent as that particular

portion of a cycle (i.e., a scram from 50% power is counted as one-half

a cycle). While this appears to be conservative, the oasis for this

assumption is not based on an engineering evaluation. Because this

item has been open since November 17, 1976 with marginal progress toward

completion of the necessary corrective action, this item is upgraded

to an unresolved item.

(0 pen) Inspector Follow Up Item (IR 50-267/77-10): Surveillance of

pipe supports and restraints. Hydraulic snubber BFS 398E has been

repaired, however, corrective action for the remaining items has not

been completed. (See paragraph 6 of this report.)

(0 pen) Inspector Follow Up Item (IR 50-267/77-09 and 77-14): Plant

operating items. The specific items noted in the two reports have

l been corrected, however, a mechanism for designating and assuring that

t

these panels which may be left open or alternately must be closed has

not been formalized.

(0 pen) Inspector Follow Up Item (IR 50-267/78-14): Pulled fuses.

While all fuse blocks have bcen checked, an outstanding Corrective

Action Report (CAR) Numt-ar 538 relative to marking or tagging of

those blocks not requiring fuses remains outstanding.

(0 pen)InspectorFollowUpItem(50-267/78-06): Modification

necessary to allow Functional Testing of level Switches. Change.

Notice 763 necessary to install test connections which would allow

functional testing of a number of level switches, i.e.: LSH-21451,

LSH-21452, LSH-21453, LSH-21385, LSH-21440, LSH-21441 has not been

completed. Because the capability to functional test the level

switches is necessary and the scheduled completion date for the

change notice has not been met, this item is upgraded to an

unresolved item.

(Closed) Inspector Follow Up Item (50-267/78-06): Inclusion of

certain level switches in the calibration / functional test program.

The inspector has determined that those System 21 level switches

noted in the subject report have been included in the Fort St. Vrain

calibration / functional test program.

(0 pen) UnresolvedItem(50-267/78-08): Inconsistencies in Procedure

SR 5.3.5-A, Hydraulic Power System Calibration. The inconsistencies

in the surveillance procedure remain uncorrected. The inspector

reviewed CAR 756 and two pieces of internal correspondence dated

June 4,1978 and July 1,1978 requesting that action be taken to

correct the inconsistencies.

(Closed) Item of Noncompliance - Infraction 1.a (50-267/78-08):

Failure to analyze cleaning agents. The licensee has revised

Administrative Procedure ADM-12, " Maintenance and Repair Procedure,"

to provide specific cleaning agents which may be utilized. Additionally,

an engineering study, dated June 23, 1978, by PSC concluded that the

previous cleaning of stainless steel components had not been

detrimental.

(0 pen) Item of Noncompliance - Infraction 1.b (50-267/78-08):

Failure to control weld rod. A form for weld rod control has been

developed to be utilized by plant maintenance, General Atomic and

Stearns-Rogers. Revision of the necessary procedures is expected

to be completed by August 25, 1978.

(Closed) Item of Noncompliance - Deviation (50-267/78-08): Failure

to keep records. A requirement to maintenance records of solvents

and cleaning solutions utilized on stainless steel parts has been

incorporated into Maintenance Procedure MP-04, " Administrative

Policy for Maintenance Procedures." Additionally, this require

ment has been approved for all required procedures by the Plant

Operating Review Comittee in meeting number 268, dated August 9,

1978.

3. Environmental Qualification of Safety Related Electrical Equipment

The inspector determined that the licensee had assigned responsi-

bility for review of those items requiring review by the licensee

in IE Circular 78-08, " Environmental Qualifications of Safety

Related Electrical Equipment at Nuclear Power Plants." Each of the

items enumerated had been compared with his plant circumstances and

resulted in a determination that no corrective action was necessary.

The status of each of the items is as follows:

a. Connectors: Response to IE Bulletins 77-05 and 77-05A

submitted December 12, 1977 included data to support con-

clusion of adequacy.

b. Penetrations: IE Bulletin 77-06 sent to licensee for

information only - Electrical Penetrations not utilized.

c. Terminal Blocks: Response to IE Bulletin 78-02 submitted

February 17, 1978. No unprotected blocks of the type

specified utilized.

d. Limit Switches: Response to IE Bulletin 78-04 submitted

March 9,1978. No NAMCO D2400X or EA-170-302 snap lock

switches utilized in any safety related equipment. NAMCO

EA-170-11100 snap lock limit switches utilized and test

data to support conclusion of adequacy contained in

submi ttal .

e. Cable Splices: IE Circular 78-08. No electrical penetrations

utilized and no splices are allcwed unless inside control

cabinets in accordance with Electrical Design Installation

Specification 1N2.

f. Other Potential Problems: IE Circular 78-08.

(1) Radiation and temperature effects on electrical cables:

No electrical cabling utilized in these types of areas.

(2) Temperature limitations on nylon components of solenoid

valves: Detennined that nylon components are not utilized.

(3) Adequacy of qualification testing of components by

seperate effects versus sequential testing of environ-

mental parameters and qualification of electrical

transmitters: Reviewed in 1977 and problems found were

corrected.

No items of noncompliance or deviations were identified.

4. Records

The inspector reviewed the licensee's program for the control,

storage, retention and retrieval of records and documents for

conformance to Technical Specification requirements.

Charts TR4637 and TR4638 were among the records selected for

retrieval and inspection. These are three-pen recorder charts

for PCRV cooling water inlet and outlet temperature and concrete

surface temperature. Concrete surface temperature was not

recorded on chart TR4637 for the period March 11-17, 1978.

Neither concrete surface temperature nor cooling water outlet

temperature was recorded on chart TR4638 for the period March 10-17,

1978. No plant trouble reports (PTR) requesting recorder maintenance

could be located for this period. The licensee's failure to properly

monitor the performance of these recorders and to initiate a PTR

for corrective action is an apparent item of noncompliance with

Fort St. Vrain procedure ADM-28, " Administrative Procedure for

Data Logs, Data Sheets, and Charts." This procedure requires

that such recorders be checked once each shift to be sure that the

recorder is inking and reading properly and that a PTR be written

if the recorder is not working properly.

For the period of March 11-17, 1978 the data available is insuffi-

cient to document compliance with Technical Specification LC0 4.2.15.

This problem has been previously identified by the licensee for

other LCO's and the generic problem is addressed in Corrective Action

Requests 403 and 404 and in Quality Assurance Deficiency Report 375.

The inspector will monitor the licensee's progress in developing

a system of documenting compliance with LC0's. This item is

unresolved.

5. Cleanliness

l The inspector reviewed the administrative controls that the licensee

has established to assure adequate housekeeping and cleanliness. The

inspector conducted discussions with personnel and a tour of the

l

facility in order to detennine the effectiveness of these controls.

During the facility tour, housekeeping conditions were observed to

be generally satisfactory. An exception to this was the auxiliary

electrical room where the following conditions existed:

-

Three empty cardboard boxes were present.

-

One cardboard box containing styrofoam packing was present.

,

-

One cardboard box was being used as a trash container.

.

-6-

-

Two partial rolls of used chart paper were observed in the

bottom of Panel I-47.

-

Loose teletype paper was on the floor.

The existence of these conditions is an apparent item of noncom-

pliance with the requirements of Fort St. Vrain Procedure ADM-30,

" Administrative Procedure for Control of Combustibles." This

procedure requires that parts, instruments and other supplies in

ccmbustible containers be unpacked and the packing safely stored

or disposed of before the part or instrument is taken into the

plant operating area. It further provides that if the item must

be unpacked at the work area, the combustibles shall be removed

to suitable storage imediately.

The licensee took appropriate corrective action during the period

of this inspection, and no written response to this item is

required. flo other items of noncompliance or deviations were

identified in this portion of the inspection.

6. Surveillance of Pipe Supports and Restraint Systems

The inspector reviewed the licensee's program, procedures and

schedule pertaining to pipe support and restraint systems for

conformance to the requirements of the Technical Specifications.

The inspection included a review of records, a physical inspection

of snubbers and supports during a facility tour, and a review of

open items from inspection number 77-10.

The following items noted during inspection 77-10 remain open:

-

The refueling interval surveillance procedures for hydraulic

snubbers have not been prepared.

-

The licensee has no plans to establish a surveillance program

for pipe restraints other than hydraulic snubbers.

-

The hydraulic snubber inspection program does not include an

inspection of piston and/or reservoir vents, or sample test-

ing of hydraulic fluid.

-

The licensee does not have a program for lubricating the

grease fittings of hydraulic snubbers.

The inspector identified the following new open items:

-

The U-clamps near V42387 and V42378 were not secured to the

pipe support. A plant trouble report was initiated to correct

this discrepancy.
