H.

Ronald L. Nimi.t::, Radiation Specialist, Intern, Region I

SUBJECT:

REPC9T OF ACTIVITIES AT Th". LEE MILE ISLAND The following report is provided per your request of April 10, 1979.

A.

Su=marv of Activities I arrived on site at 1000 on tiednesday, March 28, 1979 with the four other = embers of the Incident Respense Team.

We were is-mediately taken to Unit 1 Control Rocm where we were briefed by J. Seelinger, Unit 1 Superintendent, on the status of Unit 2, both operationally and radiologically.

After our initial briefing, =yself and K. Plumlee were di:. acted to perform investigatory surveys in accessible rlaat areas to determine general radiation dose ra'es.

After this was done, and for =y first two days, on site, I began collecting licensee

=eteorological, site boundary, and off-site dose rate data for presentation to C. Gallina, who transmitted this data to Region I via telephone.

On the third day, of the incident, I acco=panied licensee personnel during excursions to measure off-site dose rates.

I accompanied two different survey teams from 2100 Thursday, March 29 thru 0100 Friday, March 30, 19/9.

During this time, I collected air samples and verified licensee off-site dose rate neasure=ents. Additionally,

=yself and R. Smith conducted an independent servey of the off-site dose racas on the morning of Friday, March 30, 1979. We completed a tour, 360 around the plant, in an effort to locate a 0.5 mrem /hr isodose curve. The survey, conducted per Regional Request, was per-forned ' on 0130 to 0730 and enco= passed areas ranging from 1 to 5

=iles tha plant.

During the surveys, I collected soil and water

..les to be counted by the Region I Mobile Lab.

During my remaining ti=e at Three Mile Island, from March 30, 1979 thru April 10, 1979, I was assigned co the number one shift, 2300 to 0800 hours0.00926 days <br />0.222 hours <br />0.00132 weeks <br />3.044e-4 months <br />. My efforts during this time were directed to pre-venting any further radiation overexposures of plant personnel, in Unit 2 and to o=e extent, Unit 1.

Health Physics Supervisors and Technicians in an effort to plan and control all entries into the Unit 2 Auxiliary Building.

I reviewed portiens of the licensee's respiratory protection program and identified areas that needed " tightening of controls." During this time the licensee brought in support crews in an attempt to maintain radiation exposures to as low as reasonaoly achievable.

Narrative of Time Soent at TMI Arrived 1000 Wednesday, March 28, 1979 through 1400 Thursday, March 28, 1979.

Resumed duty 16'O and remained on duty thru to 1100 Friday, March 30, 1979.

My remaining ti=e on site, from Friday March 30, thru to April 10, 1979, was spent on the number one shift from approxi=ately 2200 thru to approximately 0930.

Total time on duty approximately 180 hours0.00208 days <br />0.05 hours <br />2.97619e-4 weeks <br />6.849e-5 months <br />. This is as compared to 80 hours9.259259e-4 days <br />0.0222 hours <br />1.322751e-4 weeks <br />3.044e-5 months <br /> which nor= ally would have been spent on duty.

My - fforts on site were under the direction of the appropriate Team Leaders.

C.

Comments or Observations Regarding Licensee Operations at the Site My main comment is that during the initial two days of the Recovery Operation, the plants, both Unit 1 and Unit 2, appeared to experience a breakdown in administrative procedures related to the conduct of the Health Physics operations at the two units.

This was evident in the lack of the issuances of Radiation Work Permits (RWPs) for entries 4.nto High Radiation and/or High Airborne Radioactivity Areas.

This particularly disturbed ze because the RWP is the basic apparatus for control of radiarion exposures at a nuclear power plant.

Another item that disturbed me was the licensee Health Physics per-sonnel permitting entries into High Airborne Eadioactivity Areas with-out any idea of the airborne radioactivity coacentration present. This was brought to the attention of senior inspectors who had identified the problem and were bringing this to the licensee management's attention.

With regard to the Health Physics Supervision, it appeared that because of the additional workload the plant staff was inadequate to handle such an incident.

It waa at this time that additional Health Physics per-sonnel and/or consultation was brought on board.

Because I did no". interact directly with plant Health Physics Manage-ce., but rather passed any concerns on to =y appropriate Team Leader on upper level Health Physics Supervision / Management.

I can not co= ment D.

Cc==ents or Observations negaEdina IE and/or NRC Ooerations at the cLte During my initial two days on si;e, our activities were quite hectic.

This was caused by the number and depth of questions generated by the Region. Al-hough at timas we were stretched fairly thin, I feel the Commi sion was able to get a handle on tne situation and with the dispatching of additional personnel, was able to more ef-fectively handle the recovery operation.
