In-Office Review of Licensee Event Recorts (LERs)

-

'

The LERs listed below were reviewed in the Region I office promptly following receipt to verify that details of the event were clearly reported including the accuracy of the descriptica of cause and the adequacy of corrective action. The LERs were also reviewed to determine whether further information was required from the licensee, whetner generic imolications were involved, whether the event should be classified as an Abnomal Occurrence, and whether the

,

event warranted onsite followup.

l The following LERs were reviewed.

LER77-23/lT,datedOctober4,1977;Violat[onorContainment

'

Except as noted in r'aragraph 5 belcw. the inscector had no further questions on these items.

5.

Onsite Licensee Event Followuo For those LERs selected for onsite followup (denoted in Paragraph

-

4), the inspector verified that the reporting requirements of Technical Specifications and GP 4703 (Original) had been met, that

appropriate corrective action had been taken, that the event was reviewed by the. licensee as required by Technical Specifications, and that continued operation of the facility was conducted in con-fornance with Technical Specification limits.

The inspector's findings regarding these licensee events were acceptable, unless othersise noted below.

LER 77-25/3L described tne failure of a RC evaporator seal

--

water line fitting. The failure was attributed to a weakene'd hose connection caused by periodic connecting and disconnecting of the reclaimed water hose used to fill the tank.

A change modification has been initiated to provide, permanent piping for seal water tank makeup.

However, this modification has not yet been approved for accomplishment.

The licensee's corrective measures to reduce stress on the seal ' water lin.e by comp 1c-tino this change modification will be reviewed during a subsequent inspection.

6.

Re ortability of Entry into a Decraded Mode The inspector discussed with the licensee's staff the following interpretation of the reportability of entry into a degraded mode.

The purpose of this thirty-day written report is to provide data on equipment failure, including inoperability.

Therefore, a report is required:

a.

When the failure is detected while performing a test required by the Technical Specifications to demonstrate operability of the equipment-This is true even if the failure is detected

.

in a mode P which the Technical Specifications do not require operability si the equipment.

b.

When the ' allure is detected while the facility is operating i

in a mode for which the Technical Specifications do not specifically state that operability of the failed equipment is not required for that mode (so that operability in that mode is required, either directly or by implication).

-

A thirty-day written report need not be submitted when equipment is

.

removed from service, for reasons other than failure, to enter alternate or degraded modes of operation consistent with the provisions of a technical specification.
