Dear Mr. Davis:
References (a) and (b) requested a SNM license for fuel and post accident monitoring detectors.
Reference (c) transmitted SNM 1938 which authorized possession and use of the detectors, but deferred action or the fuel until a security _, question was answered.
The purpose of this letter is to amend reference (a) in regard to two items which relate to handling of the fuel and conditions precedent to delivery of the fuel.
A third item requests the addition of new material to the license.
Item #1:
Section 2.3, Accident Analysis, of the Braidwood SNM License Application (Ref. a) states that any radioactivity release from a damaged fuel assembly would be relatively minor and capable af being accommodated by the Fuel Handling Building Ventilation System.
This implies that the Fuel Handling Building Ventilation System is operable during fuel receipt.
Per the present preop test schedule, this system may not be operable for fuel receipt.

I J. G. Davis July 31, 1985 Justification The Braidwood Fuel Handling Building Ventilation System is part of the Auxiliary Building Ventilation System.
Operation of this system is not necessary in the period prior to initial fuel load i
when new fuel assemblies are being received and stored in the Fuel Handling Building.
There is no need for special air temperature control, containment, confinement, or exhaust gas flitratica during this period because there is no decay heat load and no fission product inventory.
Since a new fuel assembly contains relatively minor amounts of radioactivity, the operation of the Fuel Handling Building Ventilation System would not alter the consequences of accidental damage to a new fuel assembly.
Item #2:
Section 2.2.4 of the Braidwood SNM License Application (Ref. a) describes storage and movement of new fuel.
The fifth paragraph in this section describes how the checkerboard pattern will be maintained in the spent fuel pool and states that when transporting a new fuel assembly, the loaded area of the spent fuel racks will be approached from the unloaded side.
It further states that during unloading, fuel assemblies nearest the unloaded side will be moved first, ensuring that assemblies are not moved across each other.
These conditions will prevent loading the entire core directly from the spent fuel pool.
The present controls should be replaced with the statement, "A new fuel assembly in transport will not be allowed to pass over a storage cell that is immediately adjacent to a cell that already contains a fuel assembly".
Justification The total number of times that each new fuel assembly must be handled will be minimized.
The possibility of accidental damage to the fuel will diminish, yet reasonable and satisfactory precautions are established to avoid accidental criticality.
Item #3:
Please add the following special nuclear material to the license.
- 6. Plutonium -239
- 7. scaled source
- 8. 2 microcuries
- 9. To be used for calibrating portable alpha instruments The above material is contained in Eber11ne Model # 594-1.
J. G. Davis.luly 31, 1985 Pursuant to 10 CFR 170.11 (3), we have determined that no fee is required.
Attached are fif teen copies of this letter for your use.
If you or your staff have any further questions, please address them to this o f fice.
Very truly yours, del 4
