Summary of Activities Performel: Assigned to Unit 1 in plant radwaste evaluation. Routine activities included taking periodic readings on liquid and gaseous radwaste systems, including waste gas decay tanks, bleed hold up tanks, miscellaneous waste tank, auxiliary i
building sump and tank. Non-routine activities included evaluation /
calculation / observation of the vacuum pump filtration system, l
operation of the auxiliary buildirig and fuel handling building air filtration systems, waste transfers from Unit 2 to Unit 1, assessment of leaks in a penetration area, assessment of water on the floor in i
the auxiliary building, isotcpic inventories in each radwaste tank F
where available, assessment of pH of the water released from contain -
ment, and discussions with Met-Ed representatives on planned trans-fers from Unit 2 to Unit 1.

Cemments on licensee (Radwaste) operations: Overall, the Met-Ed Radwaste operations were considered very good under the circumstances.
Of particular note was the resourcefullness of the Liquid Radwaste 1

p-Memorandum For:
Boyce H. Grier.
Supervisor who was successful in clearing highly radioactive liquid from the Auxiliary Building basement floor.
Some concerns were noted in the ventilation and radwaste areas and are as follows:
Inability to ascertain the functional capabilities of the a.
Auxiliary and Fuel Handling Building for removing radioactive iodine and methyliodine.
b.
Inability to prevent cross-contamination of relatively radio-actively cool Unit I wastes with post-incident highly radio-active wastes frcm Unit 2.
Inability to obtain timely semple returns on liquid samples.
c.
4.
Comments on IE operations: During the early phase (first week), in-plant IE personnel were effective in performing independent evalua-tions of plant and systems status, serving as " sounding board" for licensee plans. review and approval of licenses procedures, and identifying significant problems for licensee attentian. However, as more and more individuals from other organizations, like NRR and DOR, became actively involved in operations, the effectiveness of IE and even Met-Ed operators decreased. This was most apparent during the reactor coolant pump trip, when the control room had to be cleared of all non-essential periannel.
