Thomas E. Murley, Regional Administrator Region I THRU:
Richard W. Starostecki, Director Division of Reactor Projects FROM:
William F. Kane, Director TMI-1 Restart Staff
SUBJECT:
TMI-1 STATUS REPORT FOR THE PERIOD DECEMBER 13-20, 1985 Enclosed is the eleventh of a series of weekly status reports of the TMI-1 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 from 8:00 a.m., December 13 to 8:00 a.m., December 20, 1985. We will continue to issue weekly status reports for the duration of TMI-1 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 13-20, 1985 1.
Plant Status As of 8:00 a.m. on December 20, 1985, TMI-1 was at 75% power.
2.
Test Program Status 4
The licensee's planned test program and current status for restart of 3
TMI-1 are shown on the attached Figure 1.
No additional startup testing
'was conducted during this period.
3.
Facility Operations Summary
[
Steady-state operation at 75% power continued throughout the period.
4.
Items of Special Interest NRC Notifications There were no events during the period that required notification of NRC l
pursuant to 10 CFR 50.72.
Revisions to Restart Test Program On Tuesday, December 17, 1985, NRC and GPU Nuclear representatives met at the TMI Training Center to discuss the power ascension program and possible schedule adjustments in light of the operational limitation on power level.
The licensee plans no changes to their program except that all tests plan-ned for the 100% power testing plateau will be conducted at the maximum attainable power level, expected to be about 85-90%. The program calls l
for escalating to the maximum attainable power level on December 27, 1985, culminating on January 2,1986, in a planned turbine trip and reactor trip.
The scheduled startup date is January 5, 1985, but that could vary depend-ing upon test program results and any maintenance needs identified in the interim. NRC approval is required, prior to power escalation above 75%
power and prior to restart following the planned trip.
Steam Generator Level Indication The TMI-1 status report for the period December 6 - 13, 1985, discussed a discrepancy on a steam generator level instrument that the licensee had identified.
During this period, the licensee completed their troubleshooting and calibration tests. As a result of these efforts, s
i they corrected the two startup and operating range instruments which had indicated about 7% higher than similar redundant instruments for one of the steam generators.
Currently, both steam generators are operating at a water level of approximately 75% of the operating range while the plant j
is at 75% of rated power.

I Contamination Event On December 18, 1985, the licensee included in a routine weekly press release on TMI-1 restart details of a contamination event that had occurred on December 17, 1985.
The event began at 8:00 p.m. when noble gas was released into the auxiliary building atmosphere during replacement of a waste gas compressor filter. All workers leaving the building were frisked by health physics technicians.
Seven workers and one region-based NRC inspector were slightly contaminated.
In the case of the NRC inspector, only his hard hat was contaminated. The licensee estimated personnel exposures of about 0.0004 millirem from the -
contamination.
The TMI-1 Restart Staff will perform on-site followup of this event.
NRC Shift Coverage at Maximum Achievable Power The TMI-1 Restart Staff plans to initiate continuous shift inspection coverage of the planned power escalation above 75*4 power. When the plant has achieved steady-state conditions, the staff will resume coverage of twelve hours each day. The staff will also provide continuous coverage of the planned turbine trip test, the ensuing period of shutdown checks and post-trip review, and the resumption of power operation currently scheduled for January 5,1985.
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?4 of rated power. The shifts were manned by NRC personnel from Regions I and II.
One Region I project engineer, one reactor engineer, two startup inspectors, two personnel training specialists, 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, personnel training, 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 on December 27, 1985.
OFFICIAL RECORD COPY TMI WEEKLY STATUS - 0004.0.0 11/29/80
3 Contact from the press and public continued throughout the period. We l
continued to maintain contact with representatives of the Commonwealth of l
Pennsylvania during this period.
The TMI-I Restart Staff issued two daily highlight reports for the Executive Director for Operations on December 18 and 19, 1985, regarding j
the revisions to the restart test program and the contamination event, t
The tenth weekly status report for the period December 6-13, 1985, was issued on December 16, 1985.
