4 Director j Nuclear Reactor Regulations-Office of Administration i United States Nuclear Regulatory Commission Washington, DC 20555 Subj ect: Request for amendment to The Pennsylvania State University Penn State Breazeale Reactor R-2 License License R-2 j Docket 50-5 The Pennsylvania State University respectfully requests you to amend its R-2 facility license to allow the Penn State Breazeale Reactor (PSBR) to " receive, possess, and use a 3 curie sealed americium-beryllium source in connection with the operation'of the TRIGA reactor" pursuant to title 10, CFR, Chapter.1, j Part 50.
t This source is no. 930-AM-155 (P-843) manufactured by.Numec. The source is
- j. currently possessed by Northrup Corporation and was previously licensed for i
use in, connection with the use of their TRIGA reactor. The source is doubly encapsulated in type 304L stainless steel with the following specifications:
wall thickness: inner capsule - 0.040 inch outer capsule - 0.040 inch thickness of end inner capsule 0.050 inch opposite weld: outer capsule - 0.050 inch thickness of inner capsule - 0.075 inch welded end: outer capsule - 0.050 inch A drawing of the neutron source is attached.
The University already possesses several neutron sources under both the R-2 license and the by product material license. One'of the sources covered under l the by product license is a 3-curie Am-Be source, so the personnel are already -
familiar with proper handling procedures. Instrumentation is available for
- radiation surveys.
A calculation was made to determine the maximum heat that could be generated in the source when in the reactor during reactor operation. Calculations show d

+*
O Director, Nuclear Reactor Regulations Page 2 February 19, 1986 that the fission rate in the source, when the reactor is operating at one megawatt, will produce a power of less than 10 watts. Thus the source temperature will not rise significantly above ambient temperatures while in the TRIGA core.
Additional information, if required, may be obtained frou Dr. Samuel H.
Levine, Director of the Penn State Breazeale Reactor, University Park, PA 16802, 814/865-3110.
