Dear Sir,
UNC requests that the subject license be amended to modify the i
requirements for maintaining ventilation air flow between work This modification is designed to recognize that for certain areas.
areas the airborne levels are minimal, and that the airflow direction cannot impact ALARA within the facility. For one area, the Pack Assembly room, contract requirements dictats that the air pressure be positive with respect to any adjacent areas.
Also enclosed is a check for $150 for the application fee.
We request that approval of this amendment be issued by Sept.
1, 1988.
Very truly yours, Los Ah gb EK. !..........

A ventilation direction threshold of 33 dpm per cubic meter over a calandar quarter represents 15% of MPC.
This value is determined as the average for an area using all area samples for a period of one quarter, and represents values for the time in which activities are conducted in the area.
All air sample results are adjusted to allow for a 1.15 self absorption correction factor.
This factor may be changed if analysis demonstrates this to be appropriate.
Areas of the facility operating below this level are not considered to contribute meaningful uptakes to individuals.
Accordingly, the modification of air flow direction controls relative to adjacent areas will also not contribute meaningful uptakes to individuals.
