h MAY 11 1973 MEMORANDUM FOR: Boyce H. Grier Director, Region I THRU:
QNW. Crocker, Chief, Fuel Facility Projects ggshetion,FF&MSBranch FROM:
J. Roth, Fuel Facility Projects Section
SUBJECT:
REPORT OF ACTIVITIES AT THREE MILE ISLAND The following is provided per Region I Announcement No. 79-20 dated April 17, 1979.
A.
Narrative of Time at the TMI Site Arrived at the site at 1150 on April 13, 1979 and was processed through for badging by licensea representatives. Reported for duty at 1400 on the number 3 shift 'twing). All time on site was on the swing shift from about 1400 to 0030 from April 13 thru April 26, 1979.
Duty hours for April 27-28,1979 were from 1000, April 27, to about 0230, April 28,1979.
I left the area at about 1200 on April 28, 1979.
Total time on duty was approximately 170 hours0.00197 days <br />0.0472 hours <br />2.810847e-4 weeks <br />6.4685e-5 months <br /> during my stay at TMI.
B.
Summary of Activities While on site, most of my time was spent conducting off-site radiation surveys and chtain'ng air, soil, vegetation and rain water samples for environmental analys'i. This was done in off-site areas on the east and west sides of the river at distances up to 7 miles north and south of the plant.
On April 18, 1979, I escorted a shipping container loaded with a pressurized primary coolant sample from the site to the Harrisburg International Airport (Olmstead) for shipnent via a National Guard Aircraft to B&W, Lynchburg, VA.
Prior to leaving the site, I took and recorded radiation readings on the surface and at a distance of 3 feet from he surface of the shipping container.
Prior i.o take-off of the aircraft, I also conducted a radiation survey of the aircraft to assure the crew that they would not be exposed to " higher than back-ground" radiation levels while they were seated in the cockpit.

Comments or Observations Recardino Licensee Ocerations at the Site Since-I was assigned to an off-site survey team, I had little opportunity to observe lice"
'e actions or operations in the plant. However, It appears t the licensee coeld not reasonably estimate the amount a t time it would take to accomplish a task.
For example, at about 1630 on April 18,1979, I was instructed to go into the plant to escort the primary coolant sample to the airport within the next hour.
I arrived at the plar.t at about 1645, the sample was pulled at 2145, we lef t the plant at about 2250, were at the airport at about 2320 and the aircraft took off at about 2340. A task which was initially estimated to take about 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> to accomp;ish, in fact, took almost 7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br />.
While in the plant it appeared that adequate security precautiors were being taken and adequate health physics precautions were being adhered to.
D.
Comments or Observations Recarding IE and/or NRC Ooeration_s at tne Site It appeared tnat because of inadequate estimates of event timing on the part of the licensee, the environmental surveillante team, of which I was a cart, worked in a reactive mode of operation throughout the time I spent on site.
There appeared, at times, to be no chance to establish a rational survey team rescanse to gaseous releases from the plant since several of the releaeas were either unplanned or occurred hours in advance of or 2-ter the planned time.
