Dear Dr. Bryant
SUBJECT:
Walver of Criticality Monitor and Kish Radiation Area Alarm Requirements Tnis letter will serve to request vaiver of certain require-ments contained in the Code of Federal Regulations, which pertain to the continuous monitoring of reactor fuel storage areas, and to warning devices for areas of high radiation, based upon the following cocaider-ations s A.
CRITICALITY MONITORING By Reference 3, a license to tsceive, possess, and store up to 32 kg of U-235 in the form of fuel assemblies, in their original lo:ked shipping con-tainers, was requested. The fuel assemblies will be as described by Reference 2 Waiver of the

storage vault, in cylindrical containers, bolted to the wall on 15-inch centers.
License SHH-419, previously authorized an exemptson from the requirement of criticality monitoring for storage of the plate-type elements on the basis that, although no health hazard is anticipated from storage of the assemblies, adequate gansna and neutron surveys will be conducted when the maximum number of assemblies is initially stored.
i Flooding of the building, and the rooms in which the assemblies will be stored, can be discounted, since the building is designed to be airtight, its elevation is high with respect to the surrounding terrain, and more than adequate drainage exists for excess water.
- 3. HIGH RADIATION AREA AIARM Waiver of the requirement in Part 20, Section 20.203, of providing a visable or audible alarm signal for areas where the level of radiation is such that an individual might receive a dose of 100 mrem in one hour is hereby requested for two such areas of thia facility.
The Pump Room, where the cleanup domineralizer will attain an equilibruim level of 16 rem /hr at its surface, will be i
locked, and will be posted as a high radiation area. The dose rate at the center of the room will be approximately 10 mr/hr, and all personnel entering this room will be provided with personel monitoring equipment.
The second area is the base of the manhole which provides access to the shutoff valve between the core and hold tank.
A steel lid approximately three feet in diameter covers this manhole, and is padlocked. No permanent ladder is provided in this shaft, which is about 20 feet deep. The dose rate at the valva la nominally Jess than 5 rem /hr with the reactor operating while the dose rate at the lid is negligible.
Access to this manhole is limited to the operational staff and health physics and then only at times when the reactor has been shut down.
Moreover, in t.either case is it expected that the locaticns will remain high radiation areas for periods in excess of 30 days, since it is not planned to operate the reactor continuously for that long a Period of time without shutdown.

R.
