Dear Mr. Cunningham:
crag f,
Clinton Power Station Unit 1 Docket No. 50-461 Supplemental License Application for Small Quantities of SNM On behalf of Illinois Power Company, Soyland Power Cooperative, Inc., and Western Illinois Power Cooperative, Inc., application is hereby made for a license to authorize the receipt, possession, storage, and use of small quantities of Special Nuclear Material contained in (a) In-Core Neutron Detectors and (b) Alpha Calibra-tion Standards and Check Sources.
This application is being made pursuant to the requirements of Title 10, Code of Federal Regulations, Part 70.
It is requested that the license begin September 1, 1981 and remain in effect until such time as it may be incorporated into the permanent operating license.
It is requested that this license authorize the possession of the following quantities of special nuclear material:
a)
In the In-Core Neutron Detectors - not more than 1.0 gram U-235 at any enrichment.
b)
In the Alpha Calibration Standards and Check Sources -
not more than 15 micro-Curies of Pu-239.
Because of small quantities of material involved, if is hoped that the issuance of this license can be expedited.
We also wish an exemption from Title 10, Code of Federal Regulation, Part 75 es permitted by 10CFR75.3,b.1.
In addition to one ci med original, seven copies of *

1.0 GENERAL INFORMATION 1.1 IDENTIFICATION OF PLANT AND MATERIAL TO BE LICENSED 1.1.1 Identification of Reactor, Geographic Location,_
Docket and Construction Permit This application is submitted for Unit 1 of Clinton Power Station.
This unit is a BWR-6 boiling water reactor (218 inch vessel) designed and supplied by General Electric Company.
The unit will have a rated core thermal power level of 2894 Mwt.
The station is located about 6 miles east of the City of Clinton in DeWitt County, Illinois.
The coordinates of the station are approximately 40 10' 19.5" latitude and 88 50' 3.0" longitude.
The construction permit application for Clinton Unit I was docketed on October 30, 1973 on AEC. Docket Number 50-461 and was issued Construction Permit Number CPPR-137 on February 24, 1976.
The information set forth in the application for an operating. license for the station, dated August 1980, is hereby incorporated into this application by reference.
1.1.2 Type and amount of material This license is requested for the small quantities of special nuclear material contained in (a) In-Core Neutron Detectors and (b) Alpha Calibration Standards &
Check Sources.
The. amounts of Special Nuclear Material are tabulated below:

The in-core neutron detectors may be installed in the reactor core prior to receipt of the operating license.
Ocher than storage, this is the only use of these items prior to receipt of the operating-
-license.

The alpha calibration standards and check sources will be used for calibration or instrument checks on portabic or: installed radiation monitoring equipment.
Other than storage, this is the_only-use of these items.
'1.2 STORAGE CONDITIONS 1
s
1.2.1 In-Core Neutron Detectors Prior to installation, all detectors will be stored under lock and key in the Clinton permanent warehouse.
The Clinton warehouse is designed and operated so as to assure a level of security and control of quality items.
1.2.2 Alpha Calibration Standards & Check Sources When not in use, alpha calibration standards and check sources will be stored in locked cabinets and drawers in controlled storage area (s) in the Rad / Chem laborctories, radiation protection office, radiation counting rooms, and/or the instrument calibration l
facility.
l 1.3 PHYSICAL PROTECTION The quantity of U-235 (contained in uranium enriched to 20% or more in the U-235 isotope), or plutonium i
I to be possessed under this license is less than the l
l quantity specified in 10 CFR 73.l(b) of 10 CFR 73.
Therefore, the physical protection requirements specified therein do not apply.
1.4 TRANSFER OF SPECIAL NUCLEAR MATERIALS i
Because there are not more than 15 grams.of fissile material subject to this license, this material is exempt from the packaging and transfer requirements of 10 CFR Part 71.
1.5 FINANCIAL PROTECTION AND INDEMNITY L
Because this license does not involve Special Nuclear Mat-yerial for use as. fuel,-the proof of. financial protection-,_.
F 1.5 (continued) required Enr 10 CFR 140.13 does not apply to this license.
2.0 HEALTH & SAFETY 2.1 RADIATION CONTROL 2.1.1 Training and Experience The technical qualifications for-personnel with Radiation Protection responsibilities are described in Section 13.1.3 of the FSAR.
2.1.2 Contamination Monitoring Contamination control is discussed in Subsection' l
12.5.3.4 of the Clinton FSAR.
In addition, various station procedures provide specific guidance for checking for contamination.
a)
Receipt of Radioactive and Fissile Material b)
Contaminated Materials Guides and Control r
c)
Radiation Survey Techniques d)
Decontamination of Area / Equipment Table 12.5-2 of the Clinton FSAR describes the equip-ment to be used in checking for contamination.
l In addition, Clinton Power Station procedures require 1
that the alpha calibration standards and check sources be leak tested upon receipt and at subsequent interval.s every three months.
2.1-3 Calibration and Testing of Instruments The calibration and testing _of radiation monitoring instruments is discussed in Subsection 12.5.3.2.8 of-1
i 2.1.3 (continued) the-Clinton FSAR.
Station calibration procedures and frequencies will be based on information provided by the instrument vendor.
2.2 NUCLEAR CRITICALITY SAFETY Because the amounts of fissile material are much less than required for criticality, this material is exempt from the criticality accident requirements of 10 CFR 70.24.
2.3 ACCIDENT ANALYSIS As discussed in sections 1.2.1 and 1.2.2, utmost care will be exercised in the safe storage of the in-core neutron detectors and alpha calibration standards &
check sources.
The in-core detectors contain very small quantities of uranium and no plutonium.
The uranium is only mildly radioactive, therefore any accident that could affect the safety of storage will have very minimal consequesnces.
The alpha calibration standards and check sources contain extremely small quantities of plutonium.
These items will be stored in locked cabinets and drawers in controlled storage areas.
There' fore, any accident that could affect the safety of storage is expected to have minimal consequences.
3.0 OTHER MATERIALS REQUIRING NRC LICENSE l
Requests' for licensing of other materials requiring l
NRC licence will be made via separate license applications.

V n
o 4.0 TECHNICAL QUALIFICATIONS The technical qualifications of the Clinton station personnel are detailed in Chapter 13 of the Clinton FSAR.
In addition, a plant procedure outlining the Special Nuclear Material program requires that a SNM custodian be appointed by the station's Technical Supervisor.
The SNM custodian is responsible for --
a) maintaining records of SNM inventories, movements, and locations; b) isotopic content calculations for SNM; c) authorizing fuel transfer; d) preparing nuclear material transaction and status reports; e) and coordinating receipt and shipment of nuclear fuel, The SNM custodian'will have training and experience in reactor engineering and will have specific expertise in the areas of reactor, nuclear fuel, and nuclear instrumentation design.
The technical qualifications of the SNM custodian will be maintained by the station's training department.
