SUBJECT:

PILGRIM STATUS REPORT FOR THE PERIOD SEPTEMBER 25 -

OCTOBER 8, 1986 Enclosed is the Pilgrim weekly status report from the NRC Resident Office at Pilgrim. Two NRC Resident Inspectors . monitored routine activities at the plant during the report period. In addition five region based inspectors were onsite during portions of the period. The reactor remained in cold shutdown throughout.the period for maintenance.

These status reports are intended to provide NRC management and the public with an overview of plant activities and NRC inspection activities. Subsequent in-spection reports will address many of these topics in more detail.

ENCLOSURE PILGRIM STATUS REPORT FOR THE PERIOD SEPTEMBER 25, - OCTOBER 8, 1986 1.0 Plant Status As of 8:00 a.m. on October 8,1986, the reactor was in cold shutdown with reactor coolant temperature at about 100 degrees Fahrenheit.

2.0 Facility Operations Summary The plant has been ' shut down for maintenance, and to make program improvements since April 12, 1986. Boston Edison announc'ed on July 25, 1986 that the present outage will continue until early 1987 and will include refueling of the reactor.

3.0 Items of Special Interest Annual Emergency Preparedness Exercise Schedule Change The NRC and Boston Edison have agreed to postpone the annual emergency preparedness exercise from October 23, 1986 to December 10, 1986. The postponement will allow other agencies to participate in the drill.

Main Steam Line Weld Flaw Indications During each reactor refueling outage the licensee is required to perform an extensive. inservice inspection (ISI) program. As part of this ISI pro-gram, nondestructive examinations of numerous reactor coolant system welds are conducted. The purpose of these examinations is to identify any early sign of pipe or weld cracking. Indications of flaws in or around the welds are documented and evaluated to determine possible cause and effects.

During this report period the licensee began inspection of welds associated with the reactor main steam lines. Five main steam line flaw indicatisns have been identified and are being evaluated by the licensee. The flaw indications are small enough (one inch or less in length) that they do not pose an immediate concern regarding piping integrity. The licensee reported discovery of the indications to the NRC' via the Emergency Notifi-cation System (ENS). The inspectors will review the licensee's evaluation of these indications, and any repairs needed.

Hydraulic Shock Suppressor Damage As part of the inservice inspection (ISI) program described above visual examinations of piping system supports are conducted. One type of piping support is a hydraulic shock suppressor. This component allows the pipe to move freely during system expansion and contraction, but will act to suppress any abnormal higher velocity vibrations as might be experienced in'an earthquake. During examination two damaged supports were identified.

2 The NRC was notified via ENS on October 3,1986. The licensee ~is evalu-ating the damage to determine if it would have affected the ability of the component to function.

Ongoing Fire Protection System Walkdowns Certain equipment important to safe operation of the plant is protected by fire barriers. These barriers prevent a postulated fire from spreading to adjacent areas for at least three hours, allowing time to extinguish the fire. The licensee is required to periodically inspect' the fire barriers to ensure their integrity. If any deficiencies are identified the licensee is required to take compensatory measures which include establishment of a continuous or hourly fire watch. A series of ongoing inspections has identified numerous discrepancies between the fire barriers and the inspection acceptance criteria. The licensee is evaluating these discrepancies to determine if they affect-the barriers ability to withstand a fire. Necessary repairs and compensatory fire watches have been initiated.

On October 1, 1986 the licensee notified the NRC via the Emergency Notification System that 17 instances in a twenty-four hour period had been identified where ' hourly fire watches were not properly documented and probably missed. No fires occurred during the time period, however, missing the required watches is not acceptable. . The licensee is taking steps to ensure that similar situations are avoided in the future. The NRC will monitor these~ actions for effectiveness.

4.0 NRC Staff Status during the Period Two NRC Resident Inspectors monitored plant activities between September 11, and September 24, 1986. The resident inspector staff at Pilgrim during the report period consists of the following:

Martin McBride, Ph.D. --- Senior Resident Inspector Jeffrey Lyash --- Resident Inspector A region based inspector was on-site during the week of September 29 to assist the resident inspectors. Also, two specialists inspectors from Region I were on-site during the week to inspect previously identified NRC items in emergency planning and environmental effluent monitoring.

Two NRC region based operator' licensing examiners were onsite from October 1 - 3, 1986 to inspect Boston Edison's licensed operator requalification training program.
