Dear A1:
l Enclosed is a brief description and our safety analysis of using the reactor bay as a collection point for small amounts of chemical wastes produced by various campus activities.
The accumulated waste vould be shipped periodically to waste disposal sites off campus.
If you think that there is reasonabic probability of getting NRC approval. then we will want to make an official request.
Let us know your-thoughts.

l 7/4/r; Use of the Reactor Building as a Chemical Waste Storace Area Introduction l
l The - University of Kansas is seeking permission to remodel two corners of the reactor bay to be used for as a collection point and for transient storage of. waste chemicals.
The wastes are generated by various campus activities and will be periodically _ shipped to off-campus disposal sites.
Current plans are to construct a waste storage area in the southeast and
]
southwest corners of the reactor bay.
Each waste storage area j
will be. built with fire walls and a fire resistant ceiling, a metal fire door, a berm around the floor to contain spilled
)
i
- 11gulds, an interior smoke detector, an automatic fire extinguishing system, and explosion-proof lighting and l
l ventilation systems.
The largest volume of chemicals stored in the waste storage area would be bulk waste solvents.
Four to six 55-gallon barrels or the equivalent volume in DOT' approved 5-gallon containers would be the maximum stored at any time.
Presently, the most common waste solvent which would be stored is an l
acetonitrile / methanol / water mixture used in~high pressure liquid chromatography.
Other commonly stored bulk materials would be waste paint solvents consisting largely of naphtha, and waste chlorinated solvents such as methylene chloride and chloroform mixtures.
Other wastes stored in the structures could be DOT rated as poisons, corrosive solids or 11gulds, flammable liquids and solids, or oxidizers. These would be stored in their original containers, most of which are of 250 grams or smaller.
Explosive materials will not be stored in these structures.
Safety Analysis A worst case incident would involve a leak from one of the bulk solvent barrels, and the liquid pooling on the floor.
The I
i l
Ventilation system should not allow the fumes to build up to i
explosive concentrations.
The liquid would be contained by the l
berm, and could not leave the structure.
The worst case incident l
would have the liquid then ignite-from an unknown source.
The flames should set off the internal fire detector', and the fire should be extinguished by the internal system. The fire should not burn long enough to cause an explosion by heating another barrel, or to ignite other containers in a separate storage bay.
This fire would cause no radioactive materials to be spread l
from the reactor concrete structure (the only remaining activity-due to the reactor), or from low-level radioactive waste stored in other areas of the reactor bay.
Since all the remalnjng reactor-induced activity is in the inner parts of the concrete shield, it would require an unbelievably large explosion to release any reactor-related actAvity.
Such an explosion is not deemed credible.
Siof.iclusion Storage of limited amounts of waste chemicals in the reactor bay will not appr~ciably increase the chance of spreading radioactive material from the reactor structure
