.A9 Information Needed For Processing Applications Relating to the Request to Expand Storage Capacity in Spent

' Fuel Storage Pools at L.ight Water Reactors m.,.

1)

Uhat are the specific needs that require increased storage espacity in the spent fuel pool (SFP)?

Include in the response:

a) status of contractual arrangements, if any, with fuel-storage or fuel. reprocessing facilites, and b) propo;;ed refueling schedule.

2)

What is the total construction cost associated with the proposed modification of the SFP storage facilities?-

3) What are the alternatives to increasing the storage capacity of the SFP?

The alternatives considered should include:

a) shipment to a fuel reprocessi.ng facility-b) shipment to another reactor site

[

c) shutting down the reactor b

g The discussion of options (a) and (b) should include a cost comparison in terms of dollars per KgU stored. The discussion of (c) should include the

-]

cost for providing replacement power either from within or outside the licensee's. generating system.

4)

Provide data on the empty weight of the new storage racks and the associated neutron absorbing racks if any are used.

Discuss the kinds and quantities of materials th'at v;ould be used in the proposed modification, for example, d

the amounts o.f stainless steel or boral.

5)

What would be the additional time period that spent fuel assemblies could be stored onsite as a result of the proposed expansion?

6) What would be the additional heat load and the anticipated maximum temperature of the water in the SFP which would result from the proposed expansion?

7)

How much additional solid waste would result frcm the proposed expansion?

8)

Provide data on the quantities of Ysrypton-85, Tritium, and Iodine-131 that have been measured as releases to the environment from the fuel bQilding ventilation system during each year from the last three years.

If data are not available from the ventilation system, provide data measured from the overall plant.

9) What would be the maximum radionuclide concentration (u Ci/cc) ifi the SFP 5

- as a' result of the proposed expansion? Estimate the incremental dose rate above the: surface of.the SFP that would result fro. the proposed modification.

Estinate the increased annual occupational su;n/ rcra exposure based on operations perforced by personnel'in the pool. vicinity.

J 10)

Discuss the effect of the proposed edification on the efficiency of the filter system in the fuel storage building.

==J

s:

ll)

Discuss potential fuel handling and fuel cask accidents and address the resultant doses that could ensue from such accidents relative to the

?

expanded SFP.

12)

Discuss the way'in which the original spent fuel. storage racks would be removed and disposed of or stored.
