APR 2 6 mg MEMORANDUM FOR:
Boyce H. Grier, Director, Region I FROM:
Donald J. Perrotti, Radiation Specialist, Environmental and Special Projects Section, Region II
SUBJECT:
TRIP REPORT - ACTIVITIES AT THREE MILE ISLAND 1.
The undersigned was in the first group of RII personnel who arrived via chartered flight on March 30, 1979, at approximately 4:00 p.m.
Work hours on the swing shift were from approximately 2:00 p.m. to 1:00 a.m. daily, March 30 to Apri' 13, 1979.
Departure from the site was 12:30 a.m. on April 13, 1979.

Su-ary of Accivities Perfor=ed:
Routine duties included perfor ing field radiation surveys for plume monitoring, recording data frem survey teams and in-plant area and process monitoring systems.
From April 6-13, assigned as Team Leader for the swing shift Environmental Monitoring Team. Routine duties included dispatching field monitoring teams, directing environmental soil, vegetation and air sampling activities based on field surveys and TLD results, kept IE:HQ informed of any major plant evolutions and pertinent environmental survey res sits via the hotl'ine telephone.
Cotrdinated DOE survey teams and DOE mobile lab activities through DOE Co _.and Post along with the NRC survey team to provide maximum environ-mental surveillance. Received and recorded Av.S aerial survey data for routine fl!' hts.
Maintained a shift environmental log which included ueteorological data, ground survey data and important shift activities. Prepared an environmental shift su==ary each day for the IE Director's briefing.
Received environmental survey results from other local and governmental agencies (DOE, EPA, State of Pennsylvania DEH).
Incorporated meteorological data and environmental survey results from TLD's, ground surveys, aerial flights, etc., in the updating of the Three Mi.le Island PN.
Coordinated the transportation of team members to and from the site.
Non-routine duties included dispatching NRC and DOE survey teams to specific areas when informed by in-plant HP inspectors of an activity that could result in a release. Dispatched special AMS C0hTACT:
D. J. Perrotti 242-4179 79062129 W4M 71M 241 lb2
-2' APR 2 61979 aerial surveys during releases. Directed special ground surveys and air sampling during and after potential releases. Other activities as directed by the Environmental Group Leader.
3.
Ccaments on Licensee Operations:
No direct contact was made with licensee employees, except for administrative purposes (ID badge, auto parking pass, etc.).
There were, however, several instances when there was a lack of coc=unication/
coordination between licensee employees and IE in-plant EP inspectors, who would notify the Environmental Group of an imminent release.
In these instances, the Environmental Group was unable to anticipate the releases and the surveys were done
~
after the releases occurred.
4.
Cc=ments on IE Operations:
IE environmental survey teams were able to identify plume direction and radiation exposure rates by direct radiation readings at ground level, but were unable to determine airborne radioactivity concentrations (particulate and iodine) due to a lack of air sa=pling equipment. The DOE teams were so equipped and furnished this data to the IE Environmental Group. The TLD program was offective in determining average 24-hour radiation exposure rates for all areas surrounding the plant.
IE in-plant HP inspectors were ef fective in keeping thc IE Euvironmental Group informed as to weather status, in-plant radiation levels and plant activities which could have an effect on environmental radiation levels.
