4 The inspector reviewed random selections of completed surveillance proce-dures and found three examples (listed below) of failure to comply with surveillance procedures of safety related equipment.

These were discussed with the Maintenance Superintendent.

a ~

Procedure

MHP 4030 STP.023, performed on September 17, 1984, for the Unit 2 "N" Train batteries requires verification that the voltage of each connected cell has not decreased more than 0.05 volts from the values recorded during the acceptance test.

Com-parison of the acceptance test values obtained from the Maintenance Engineer shows cell 6 had decreased 0.06 volts from the value recorded during the acceptance test.

This is a failure to comply with 12 NHP 4030 STP.023.

b.

Procedure

NHP 4030 STP.013, performed on December 26, 1984, for the Unit 1 AB batteries, requires the specific gravity be corrected to 77'F. This is accomplished in Step 7.4 by averaging the tempera-ture of the selected cell and using this temperature to determine the specific gravity temperature correction.

The data documented in Attachment 2 contains a math error which resulted in the use of the wrong average temperature and the wrong correction factor.

This is failure to comply with 12 NHP 4030 STP.013.

c ~

Procedure

NHP 4030 STP.025, performed on April 10, 1985, for the Unit 2 AB batteries, requires the average cell temperature be deter-mined by averaging the cell temperature of every 6th cell (19 cell total).

Table 1 shows the reading for cell 24 was not recorded resulting in the total temperature for 18 cells being divided by 19 to obtain the cell average.

This is failure to comply with 12 MHP 4030 STP.025 Unit 1 and 2 Technical Specification 6.8.2.c requires that written pro-cedures shall be implemented covering surveillance and test activities of safety related equipment.

Failure to comply with 12 NHP 4030 STP.013,

.023, and 025, as described above is a violation of.Technical Specifica-tion 6.8.1.c.

(Violation 315/85014-04; 316/85014-03).

One violation, and no deviations were identified.

'a ~

In response to a regional request regarding the use of temporary door restraints on Ice Condenser Lower Inlet Doors, the inspector found that 24 temporary door restraints '(in the form of tape)

were used in Procedure 12 THP 4030 STP.207 Rev. 9, "Ice Condenser Lower Inlet Doors". The temporary door restraints were used to ensure that the lower inlet doors were opened one at a time, until the initial door opening torque was measured for each door.

The procedure contained steps to remove the 24 lower inlet door restraints after the surveillance was complete and verification of removal was required on a sign-off sheet.

In reviewing the procedure, no inadequacies were found regarding the use of temporary door restraints.
