20555 Attention:
Mr. William T. Crow, Section Leader RE:
WM.
H.
ZIMMER NUCLEAR POWER STATION-UNIT 1 REVISION OF LICENSE APPLICATION FOR STORAGE ONLY OF UNIRRADIATED REACTOR FUEL AND ASSOCIATED RADIOACTIVE MATERIAL - LICENSE NO. SNM-1823 Gentlemen:
Enclosed are eight (8) copies of revised pages to our license application for storage only of unirradiated reactor fuel and associated radioactive material at the Wm.
H.
Zimmer Nuclear Power Station-Unit 1.
These revisions (underlined in red) are with regard to three (3) fuel handling cranes to be utilized for receiving and storage of fuel assemblies as outlined in Section 7.
Please amend the subject license to incorporate these revisions and insert the replacement pages into the eight (8) copies of the license application transmitted to you with our letter of March 14, 1978.
Very truly yours, THE CINCINNATI GAS & ELECTRIC COMPANY j

STORAGE CONDITIONS (Cont ' d) 7.2 Receiving (Cont'd)
M4, Sheet 1 and 2).
Here the shipment is initially inspected, the inventory checked against the receiving documents and receipt of cleararice for unloading obtained. Each container is unloaded frcm the truck trailer using a fork lift truck, cherry picker, or crane sling in combination with the overhead crane or the 4 ton new-fuel handling jiberane.
TF outer shipping containers will be removed and the fuel bundles, still within their metal containers, will be lifted using the reactor building crane to the refueling floor for removal from their containers, inspection, channeling and final storage prior to fuel loading.
Elevations and plan views of the reactor building showing the fuel storage areas are shown on Figure M-8.
7.3 Storage As described in Section 7.2, the metal fuel containers are lifted to the refueling floor, elevation 627' 9" of the reactor building utilizing the reactor building crane auxiliary hook.
Temporary storage space for the fuel containers is provided on the north and west portions of the refueling floor.
From the temporary storage location, each metal container is positioned horizontally on the operating (refueling) 2215 107
, 7.
STORAGE CONDITIONS (Cont'd) 7.3 Storage (Cont'd) floor, the cover removed, the contents visually inspected to verify that no damage during shipping has occurred, and radiation control measures as described in Section 11 are implemented.
After installation of special fuel bundle holddown bars and removal of the end cover, the container is pivoted to the vertical position and secured to a vertical support adjacent to the fuel inspection stand.
Each fuel bundle is removed in turn from the con-tainer and is transferred to the new fuel inspection stand.
The fuel inspection station is a " clean" area where the assemblies are checked for damage, clear. lines s, and specified clearances.
Following inspection, the fuel assemblies are channeled and placed in the spent fuel storage racks, located in the spent fuel storage pool, Figure M-8.
Movements of fuel containers on the reactor building 627' 9" elevation are accomplished using the auxiliary hook of the reactor building crane and/or a wheel mountcd crane (cherry picker) temporarily placed on the 627' 9"
elevation.
Fuel assemblies will be moved using the reactor building crane auxiliary hook, the refueling platform fuel grapple, the 1,000 lb. fuel handling jib-
_ crane _or__ the temporary wheel _ mounted _ crane _.

STORAGE CONDITIONS (Con t ' d) 7.3 Storage (Cont'd) mounted crane consists of a rotating superstructure with telesaoping boom, mounted on a platform equipped with rubber-tired wheels, storage outriggers _and a propane fueled diesel engine.
The crane shall be load tested to at least 2200 lbs. which is approximately 110% of a loaded metal shipping containers weight of 1900 lbs., and 320% of a fuel bundles weight of 6G5 lbs.
puring tne load test, the boom shall be extended to its maximum permitted limit and lowered to its minimum permitted elevation angle.
Further discussion on the receipt and handling of new fuel is also provided in FSAR Section 9.1.4.3.1.

STORAGE CONDITIONS (Con t ' d )
7.5 New Fuel llandling Cranes The approximate weight of a new 8 x 8 fuel assembly is 685 pounds.
The cranes listed below, and further described-in FSAR Section 9.1.4, will be used for handling the new assemblies.
7.5.1 The reactor building overhead crane with a 110 ton main hoist and a 10 ton auxiliary hoist.
7.5.2 The refueling platform with a 1200 pound fuel grapple.
7.5.3 The 1000 pound jib crane.
7.5.4 The 4, ton new fuel handling jib crane.
7.5.5 The temporary whe_el_ mounted _ crane (cherry picker).
7.6 Fire Protection The temporary new fuel storage area and the spent fuel pool are located on the reactor building refueling floor, elevation 627' 9".
The details for the fire protection systems provided are presented in the " Fire Protection Evaluation Report" for Unit 1, issued February 4, 1977.
The refueling floor consists of structural concrete and the walls and roof are constructed of steel framing with corrugated metal siding.
There are no combustibics normally located in the area, thus the fire loading is negligible.
Any possible fire in the area would involve transient materials possibly present during fuel transfer.
No accumulation of flammable material is permitted.
