DEC 18 1985 Docket No. 50-289 MEMORANDUM FOR: Thomas E. Murley, Regional Administrator Region I THRU:
Richard W. Starostecki, Director i
j Division of Reactor Projects FROM:
William F. Kane, Director TMI-1 Restart Staff
SUBJECT:
TMI-I STATUS REPORT FOR THE PERIOD DECEMBER 6-13, 1985 i
The enclosure is the tenth of a series of weekly status reports of the TMI-I Restart Staff.
These reports are intended to provide NRC management and the public with highlights from an NRC regulatory perspective of the TMI-1 restart activities for the previous week.
Subsequent inspection reports will address most of these topics in more detail.
The enclosed report covers the period frem 8:00 a.m., December 6 to 8:00 a.m.,
December 13, 1985. We will continue to issue weekly status reports for the duration of TMI-I Restart Staff activities. An overview of the chronological status of the restart effort is shown on the figure which is attached to this report.

ENCLOSURE TMI-1 STATUS REPORT FOR THE PERIOD DECEMBER 6-13, 1985 1.
Plant Status As of 8:00 a.m. on December 13, 1985, TMI-I was at 75% power.
2.
Test Program Status The licensee's planned test program and current status for restart of TMI-1 are shown on the attached Figure 1.
No additional startup testing was conducted during this period. The licensee plans to remain at 75%
power until late December 1985.
3.
Facility Operations Summary Steady-state operation at 75% power continued throughout the period.
4.
Items of Special Interest NRC Notifications n
There were no events during the period that required notification of NRC pursuant to 10 CFR 50.72.
Proposed Revisions to Restart Test Program On Tuesday, December 17, 1985, at 10:00 a.m., NRC and GPU Nuclear representatives will meet at the TMI Training Center to discuss the power ascension program and possible schedule adjustments. As described in previous TMI-1 status reports, the maximum attainable reactor power level is expected to be limited to about 85% of rated power as a result of steam generator level operating restrictions.
The bases for either continuing the originally planned test sequence or deferring or cancelling certain tests will be discussed at this meeting.
NRC staff will be represented by both the Office of Nuclear Reactor Regulation (NRR) and the TMI-1 Restart Staff.
Steam Generator Level Indication During this period, the licensee identified a discrepancy on a steam generator level instrument.
Each steam generator has two startup range instruments and two operating range level instruments. On one steam generator, the startup range and operating range instruments that share common sensing lines indicated about 7% higher than the other set of instruments.
The licensee is performing troubleshooting and calibration tests in an attempt to resolve the discrepancy.

2 Enclosure NRC Shift Coverage on Holidays Since 5:30 p.m. on November 23, 1985, the TMI-1 Restart Staff has maintained a minimum shift inspection coverage of twelve hours each day, consistent with steady-state plant operation at the 75% power testing plateau. On both Christmas Day and New Year's Day, the NRC onsite coverage will be limited to unannounced plant tours by a resident inspector, unless events at the plant merit additional coverage. We will continue to maintain shift coverage of at least twelve hours a day, including weekends, throughout the rest of December.
5.
NRC Tnermoluminescent Dosimeter (TLD) Special Monitoring Program for TMI The special NRC TLDs for TMI for the period November 25-December 10, 1985, were processed at the Region I TLD laboratory.
The TLD readings are provided in the attached Table A.
The monitoring results indicate that the radiation levels at these monitoring locations remain at natural background levels.
These readings can be expected to vary slightly from period to period due to variations in natural background, independent of releases from the plants.
6.
TMI-1 Restart Staff Status During the Period The TMI-1 Restart Staff continued 12-hour shift coverage throughout the period consistent with steady-state plant operation at 75% of rated power.
The shifts were manned by NRC personnel from Region I and by a reactor operator examiner from EG&G Idaho, Inc., an NRC contractor. One Region I project engineer, one reactor engineer, two startup inspectors and two radiation specialists were on site during portions of the period to augment the resident inspection staff.
The staff's inspection plan for this period covered the primary functional areas of operations, maintenance, surveillance, restart testing and liquid / gaseous radioactive waste systems operation with the division of responsibility as noted in previous status reports.
The staff continued to evaluate the performance of licensee personnel and the plant to determine whether the licensee should be permitted to proceed beyond the next hold point, which will be reached at the end of this month after thirty days of steady-state operation at the 75% power testing plateau.
Contact from the press and public occurred throughout the period with respect to the circumstances that developed during and af ter a routine surveillance test of the pressurizer power operated relief valve during the midshift on October 25, 1985 as discussed in Inspection Report 50-289/85-25. We continued to maintain contact with representatives of the Commonwealth of pennsylvania during this period.

g.
The TMI-1 Restart Staff issued no daily highlight reports for the Executive Director for Operations during the period.
The ninth weekly i
status report for the period November 29-December 6, 1985, was issued on Decembeq 9, 1985.
Inspection Report No. 50-289/85-26 for the period October 2S-November 12, 1985, was issued on December 12, 1985. The findings were generally favorable in that no violations or other conditions adverse to nuclear safety were identified.
However, several procedure implementation problems were identified which have been reviewed further in Inspection 50-289/85-27 and will be reported in the next inspection report.

Twenty-nine environmental (offsite) locations are monitored on a two-week exchange cycle using special TLDs for the TMI site.
Two control TL0s were stored in a 1/2" thick lead shield at the NRC TMI Office for two weeks.
The baseline data for the environmental monitoring were calculated using the past ten quarters of monitoring results. All monitoring results indicate normal natural background radiation levels.
