RESPONSE TO NOTICE OF VIOLATION

ITEtt REPORTED DURING NRC-INSPECTION

CONDUCTED FROM JUNE 2, THROUGH JULY 11, 1980

NRC C0}DIENT

A.

License No. NPF-4 Technical Specification 3.3.1.1 Table 3.3-1 for Steam

Generator Water Level Low-Low and Low Steam Generator Water Level Note 7

requires that if the number of operable channels is one less than the

total number of channels, startup and power operations may proceed until

the next required Channel Functional Test provided the inoperable channel

is placed in the tripped condition within one hour.

Contrary to the above, on June 12, 1980, while operating in Mode I the

inoperable Steam Generator I uvel channel was not placed in the tripped

condition within one hour.

'

This is an infraction.

RESPONSE

The above infraction is correct as stated.

Specifically, pursuant to

Section 2.201 of the NRC's " Rules of Practice", Part 2, Title 10, Code

of Federal Regulations, the following information is submitted:

1.

Corrective steps taken and results achieved:

When indication for

LT-1474 began to deviate from the other two channels, Operations

personnel questioned the operability of the channel.

The instru-

ment shop was notified and the calibration of the channel was

checked.

It was noted that the control room indication fluctuated

over time and periodically returned to within the tolerances speci-

fied on 1-LOG-4.

A containment entry was made and it was discovered

that there was 'a steam leak on the upper transmitter isolation root

valve.

Based on these actions to determine the operability of the

channel, the channel was placed in trip when it was determined by

the Operations Superintendent that the channel was,

in fact,

inoperable.

2.

Corrective action taken to avoid further non-compliance:

Standing

Order No. I was changed to give specific instructions to the control

room operators concerning the criteria to use in determining when to

place a channel in'the tripped condition.

In the future, when the

readings noted on the control room logs do not meet the specified

acceptance tolerances, the actions specified in the appropriate Tech

Spec will be taken immediately. Any related investigation to deter-

mine the status of the subject channel will be performed subsequent

to placing the channel in trip.

3.

Date when full compliance will be achieved:

Full

compliance was

achieved by September 10, 1980.
