SUBJECT:
REVIEW OF LICENSE AMENDMENT DATED AUGUST 22, 1985
Background
By application dated August 22, 1985, Northeast Nuclear Energy Company (NU) on behalf of itself and the other licensees listed above requested an amendment authorizing the storage and use of the following special nuclear materials at MNPS, Unit 3.
Material Form Quantity Uranium enriched Flux mapping 45 mg of U-235 in uranium in U-235 isotope detectors enriched to-greater than 20 w/o in U-235 Am-Be Boronometer source 1 curie Uranium enriched in the Post-accident 25 g of U-235 enriched to U-235 isotope monitoring detectors 93 w/o in U-235 3
U-238, Np-237 Irradiation 25 x 10 microcuries surveillance capsules U-238 plus 75 microcuries Np-237 Cf-252~ Start-up sources 0.6 curies i ., ,
ADOC 4 DR C
2 SEP 10 1935 The original license stated that these materials will only be stored at MNPS, Unit 2, until permanently installed in Unit 3 after receipt of its operating license. The requested amendment would allow those materials presently stored at Unit 2 to be tested and/or calibrated at Unit 3. In addition, any material not yet received could be received at Unit 3.
Discussion A. Radiation and Nuclear Criticality Safety In accordance with approved Millstone Staticn Health Physics Department controls and procedures, special nuclear materials are stored within a locked Hi-Rad caged area located within the Unit 3 fuel building and/or designated Special Nuclear Material Storage area of Unit 2, or secured inside Unit 3 reactor system components for testing purposes prior to the receipt of its operating license. It is planned to store the Cf-252 start-up sources at either the Unit 2 or Unit 3 fuel building in a shielded container. The start-up sources, once attached to the inserts, will be placed in the spent fuel pool of Unit 3. Personnel exposures will be controlled under the approved radiation program now in effect. The pro-cedures include the receipt of radioactive materials, personnel monitoring, establishing and posting controlled areas,-operation of portable survey instruments, and issuing radiation work permits. Therefore, the radiation protection of plant personnel and the public is assured.
The total quantity of U-235 in all the detectors is less than 10 percent of the minimum critical mass for highly enriched uranium independent of configuration, degree of water moderation, and/or reflection. Therefore, there is no potential for nuclear criticality incident.
B. Environmental Protection There is no requested change to the environmental protection requirements of MNPS, Unit 3. None are required since all the materials are sealed and contain only gram quantities of radioactive material. All materials will be stored within a controlled and locked area inside the facility. Adminis-trative controls are established and maintained by radiation safety personnel to limit the time special nuclear materials are outside of approved storage areas, as well as the minimum distance of the materials to plant personnel.
In accordance with 10 CFR 51.22(c)(11), neither an Environmental Assessment '
nor an Environmental Impact Statement is necessary for this proposed action.
General The amendment application dated August 22, 1985, was discussed with Mr. Mike Smith of the Division of Safeguards and Mr. Theodore Rebelowski, Senior Resident Inspector for MNPS, Unit 3. Neither foresaw a safety or an environmental problem with the requested amendment.

3 SEP 10 1985 Conclusion 4
Issuance of the amendment authorizing the storage and use of special nuclear materials in the form of sources and detectors at MNPS, Unit 3, is recommended.
