The University operates under the direction of the Board of Regents of the University of Wisconsin System located in Madison, Wisconsin.
The President of the Board is Joyce Erdman, who is an American citizen.
The principal offices of the university are located at 1100 Main Street, Stevens Point, Wisconsin.

The special nuclear materials are stored and used in a specially equipped radiation laboratory located in the basement of the Science Building.
The radiation laboratories are out of regular traffic patterns, and are kept locked when not in use.
They are off-limits to unauthorized personnel.
Facilities consist of:
1)
A room for the neutron howitzer equipped with shower facilities and a vault for stcrage of radioactive materials.
2)
A wet lab for chemical preparation and processing.
This is provided with emergency shower facilities and perchloric-acid type hoods with wash-down.
3)
A counting room.
Postings in accordance with Part 19, Ch. 1 Title 10 Code of Federal Regulations are displayed in each room.
The special nuclear material is used and stored in the neutron howitzer.
(Visiflux I Model ND-327 manufactured by Atomic Accessories, Inc.)
The following experiments are currently done.
1)
Thermal neutron detection 2)
Simple neutron activation and radioactive decay 3)
The saturation factor 4)
The activation of silver 5)
Properties and relative scattering cross section of neutrons 6)
Fermi age of neutrons in water 3.
This license is requested for a five-year period.
4.
Special nuclear materials now licensed:
l l
32 gm (nominal) of plutonium encapsulated as a Numec Type B 2-curie plutonium-berylium neutron source.
5.
The 32 gm plutonium-berylium was originally obtained and licensed in 1964. (A copy of the lease transfer is attached.)
The source is sealed; therefore except for the decay of the Pu there is no production or loss of special nuclear materials.
No transfer of this source is anticipated.

Dr. Ronald A.
Lokken is the officer in charge of radiological safety.
Dr. Lokken has a Ph.D. in Nuclear Physics from Utah State University and completed his dissertation in nuclear spectroscopy at the National Reactor Testing Station near Idaho Falls, Idaho in 1973.
In 1966 he attended an eight-week institute at the Oak Ridge Institute of Nuclear Studies in radioisotope handling and safety.
He served as a Visit-ing Assistant Professor in Muclear Engineering at the University of Wisconsin-Madison in 1973-1974.
Others associated with the program are:
Mr. Allen Blocher.
Mr. Blocher has a Master of Science Degree from the University of Kansas.
During the summer of 1966 he attended an eight-week institute at the Oak Ridge Institute of Nuclear Studies.
Mr. Gregory Kulas.
Mr. Kulas has a Master of Science degree from Marquette University, Milwaukee, Wisconsin.
In the summer of 1964 he attended an eight-week institute at the Oak Ridge Institute of Nuclear Studies.
Dr. Francis L.
Schmitz.
Dr. Schmitz, the Department Chairman, has a Ph.D. in Physics / Physics Education from the University of Wisconsin, Madison.

Description of each device and storage container.
Enclosed with this application is a description of the Atomic Accessories Model ND-327 neutron howitzer.
(See enclosed sheets.)
This apparatus comes complete with accessories, including:
1 Plexiglass tank (for water used as moderator)
Source holders Foil forceps Locks Source handling tool 2-curie plutonium-beryllium source, described in part 4.

Proposed procedures to protect health and minimize danger to life or property.
A.
The neutron sources will normally be stored, when not in use, in the " storage" position within the howitzer.
A source-handling tool is provided with the instrument; such handling, however, should be rare (as for leak testing) and will normally be done only by the radiation safety officer.
A locking rod and lock are included for locking the cover and retaining the source in its storage position.
The irradiation port lid and closure plug will also be secured by the lock.
The keys for the above locks will be available only through the radiation safety officer, Dr. Lokken.
l USNRC For storage of radioactive isotopes outside the howitzer, a storage vault is provided in the howitzer room.
The walls of this vaul t are of lead, 2-1/2 inches thick.
The size of the vault is 29 inches high, 19 inches wide, 55 inches deep.
Rubber gloves will be worn when handling radioactive species above the 10-microcurie level.
Hands will be washed with gloves on and then gloves checked with a survey meter.
Hands will be washed ugain af ter removal of gloves.
Each area will be surveyed upon receipt of materials, to determine necessity for posting and labeling.
If such posting and labeling is required it will be done in accordance with Section 20-203 of 10 CFR 20; the radiation officer is familiar with the provisions of this section.
At the conclusion of each experiment with the howitzer, surveys will be taken to assure that the source has been returned to its storage position.
Periodic surveys of each device will then be taken to determine the integrity of the device.
Daily, upon use, surveys will be made to evaluated radiation dose received by operating personnel.
Personnel within the howitzer room will be required to wear personnel dosimeters (TLDs).
Records of dosages will be maintained.
The neutron sources will be leak-tested semiannually using the wipe technique in the following manner:
a.
The lid closure plug is removed.
b.
The handling tool is threaded into the recessed hole of the neutron source.
c.
The source is removed from the howitzer, keeping it as far from the body as possible.
d.
The source is rotated against a filter pad.
e.
The source is then returned to the howitzer and placed in storage position.
f.
The lid closure plug is replaced.
g.
The filter pad is placed in a Geiger-Mueller counter and its activity is measured.
3.
If less than 0.005 microcurie of removable contamina-tion is found, this fact is recorded in the log book.
k
r USNRC i.
If 0.005 microcurie or more of removable contamina-tion is detected, the personnel and area are immediately tested for contamination.
Measures will be taken to prevent further contamination.
The source will be considered leaking until proved otherwise.
The results of the test are recorded in the log book, The source, assumed to be leaking, is then placed in a leak proof container, the container is sealed, and the sealed package is returned to the manufacturer for repair or replacement.
Notification is sent to The Director, Division of Licensing and Regulation, U.
S.
Nuclear Regulatory Commission, Washington, D.C.
20555.
A copy is also sent to the director of the nearest NRC Regional Compliance Office, as listed in Appendix D of 10 CFR 20, describing the test results and action taken, j.
Results of all leak tests are recorded in the log book.
This completes our application for a special nuclear materials license.
