Dear Sir:
This second request for renewal of Special Nuclear Material License Number S12! 463 is submitted in reply to your undsted form letter, mail control #15198.
The United States Coast Guard Academy, New London, Connecticut 06320, requests renewal of Special Nuclear License Number, SNM 463 The original application'vas dated February 1961 and was most recently renewed in 1975.
The amount of special nuclear material is 80 grams of plutonium consisting of one two-curie Pu-Be neutron source and three one-curie Pu-Be sources encapsuled in stainless steel and manufactured by Monsanto Research Corporation, Mond Laboratory. The manufacturer's model numbers are M1180(2C1), M1183, M118 and M113 The plutonium-beryllium neutron sources will be used under the supervision of LT Robert F. O'Hara, USCG, our Radiological Control Officer. LT O'Hara, a member of our physics staff, has a general physics background and has attended a two week course entitled "The Basic Use of Radionuclides in Research" at Oak Ridge Associated Univer-He is qualified to conduct the tests specified by our license.
sities.
Presently the sole use of the plutonium-beryllium neutron sources is irradiation of Indium producing In-116 (Tg = 54m) for half life experiments.
The plutonium-beryllium capsules are stored in a model NH-3 Neutron Howitzer manufactured by Nuclear-Chicago Corporation. The neutron howitzer is located in our new physical science building, in a room having no windows and only one access door. The cinder block room has no added shielding or radiation detection devices, as they are not necessary for personnel protection. Access to the room is limited to the Radiological Control Officer and the Physics Section Chief. All required warning signs are in place.

Leak tests are conducted by the Radiological Control Officer, LT O'HARA, semiannually if the source and neutron howitzer have been used and annually if the source and neutron howitzer have not been used. A dry filter paper wipe is counted for alpha radiation using a 300 mm2 surface barrier detector coupled with a 512 channel analyzer.

Our Radiological Control Officer, LT O'HARA, has been designated in writing and charged with the responsibility of compliance with U.S.
Coast Guard Academy DPOSINST 11080.lB (enclosure 1) and all state and federal regulations pertaining to the Coast Guard' Academy's NRC Material License No. 06-02695-01 and Special Nuclear Material License No. Stai 463. Specific duties are outlined in enclosure 1.
Use of the neutron sources is limited to the Radiological Control Officer with the assistance of an interested instructor.
In the past, during periods of an active nuclear physics program, a commercial film badge service was contracted. Presently, the only exposure is due to the experiment described above and to carrying out leak tests. It is well below the quarterly limit.
Due to the extremely small amount of waste generated under both NRC licenses (less than five cubic feet, uncompressed, over a three year period), any written waste disposal instruction would be outdated before P

the next disposal.
In the past six years the Navy Submarine Support Facility, Groton, CT, has assisted us in disposal of small amounts of waste. This policy was outlined and explained in response to IE Bulle-tin No. 79-19. Our response is included as enclosure 2.
Procedures for ordering and receiving radioactive materials are included in enclosure 1.
However, we are not requesting authority to order any special nuclear material. This license renewal is only for material we presently hold.
If you require additional information please do not hesitate to call Dr. J. Richard Christman, Chief of the Physics Section at 203-443-8463, Ext. 217, FTS 642-8217 or LT Robert F. O'Hara, Ext. 372, FTS 642-8372.
