r QUESTION RE: SPECIFICATIONS OF THE MATERIAL TO EE LICENSED (Section 4.3, Regulatory Guide 10.3)
The Special Nuclear Material for which this license renewal application is made is described as follows:
Source Material:
Plutonium-Beryllium Neutron Source Type:
Sealed Sources Three (3) 1 curie sources One (1) 2 curie source Manufacturer's Name:
Nuclear Materials and Equipment Corporation Apollo, Pennsylvania Source Handling Devices:
The above sources will be used in the following devices:
Suberitical Assembly (Model 9000, Nuclear Chicago)
Neutron Howitzer (Model NH-3, Nuclear Chicago)
QUESTION RE: HOW THE MATERIAL WILL BE USED (Section 4.6.10, Regulatory Guide 10.3)
The Pu-Be Neutron Sources will be used in studies with the Subcritical Assembly (Nuclear Chicago Model 9000) or the Neutron Howitzer (NH-3).
Som'e of the experiments which are conducted are as follows:
a.
Health Physics Analysis - A survey of possible surrounding radiation.
b.
Fast Neutron Attenuation Cross Sections - A determination of neutron attenuation of cadmium, c.
Thermal Flux Mapping - To illustrate foil activation technique for determining the absolute thermal neutron.
d.
Determination of Total Cross Section of Slow Neutrons by Trans-l missions Method - A study of the exponential nature of neutron i
attenuation in matter.
e.
Gamma Spectroscopy - The identification of an unknown gamma emitter by its scintillation spectrum, f.
Absorption and Range of Beta Particles - A study of the absorption of beta particles and the determination of the end point energy.

(~%
P g2 2 U
\\.)
g.
Determination of Half-Lives; Saturation - To study the activation by neutrons and determination of the end point energy.
h.
Energies of Neutron Absorption Resonances by Self-Indication -
To measure the energy of the principal neutron capture resonance.
1.
Neutron Flux Distribution Parameters of Suberitical Assembly -
To measure reflector savings, BmZ, k gg e
and k n.
a i'
j.
Critical Approach - Experimentally predicting the critical mass 4
of an assembly, and safety procedures followed in bringing an untried multiplying the assembly to criticality.
.These experiments form a portion of a senior level university course entitled, Introduction to Nuclear Engineering (304-421/422). The experiments are supervised by Dr. George A. Ferguson. Students are not required to handle the neutron sources.
Sources are always adequately shielded in both the Subcritical Assembly or the j
Neutron Howitzer.' Transfer of sources from one to the other is accomplished with.
remote handling tongs and under full supervision of Dr. Ferguson. All personnel exposure is monitored with appropriate dosimeters.
3 A description of the training and experience of personnel (Dr.,Ferguson/
Mr. Talley) who_are involved in, or associated with, the use of'the material.
is given in the renewal application.(copy attached).
