. ?4g Gentlemen:
Regarding:
University of Iowa's NRC License Number SNM-204 Renewal Request We request renewal of our NRC license number SNM-204.
We have reviewed the guidance provided by your Washington, D.C. office in a reminder of notice of expiration, dated 4/1/85 which was received 5/2/85.
We find only minor changes which are outlined below.
THE ACTIVITY The quantity and form of the special nuclear material on hand (two five curie plutonium-beryllium neutron sources, Source A and Source B) remains unchanged.
SOURCE A_
This is a five curie source used in conjunction with a Neutron Howitzer in the education and training of graduate and advanced undergraduate students.
SOURCE B This source is in the form of sealed sources of plutonium-beryllium. The source was manufactured by Mound Laboratory, Monsanto Research Corp., Dayton, Ohio and is currently in storage.
F.EE,,.(tMP,
u I
- 8e b
j')0.//(s )(9) l This source is located in Van Allen Hall (formerly known as the g/ A Physics Building) on the campus of the University of Iowa. This location and place of use (Room 556A of Van Allen Hall) is un-changed from the location and place of use on the current g(s.d p SOURCE B, Source B is in locked storage in the basement of the Radiati h Protection Office on the campus of the University of Iowa.
The current license lists the location of Source B as locked in st g G3. N g the Chemistry Building on the campus of the University of Iowa.
l Source B has been moved from that location to locked storage in the basement of the Radiation Protection Office.

.Page Two Re: Renewal Request License No. SNM-204 USE SOURCE Ap The use of Source A remains the same as follows:
Any one of the following activities may be conducted with Source A.
Activities are conducted in accord with the manufacturer's protocol.
Production of radioactie isotopes by neutren bombardment Determination of beta energy Determination of half life Activation analysis - determination of elements present by neutron activation and analysis of resultant radiation Mappping of neutron flux Sesgregation of fast and thermal neutrons Scattering of fast neutrons Quantitative measurement'of neutrons Capture cross-section determination Total cross-section -for thermal neutron determination.
SOURCE B The use of Source B remains the same - storage.
Source B was formerly used in conjunction with the natural uranium water sub:ritical training assembly in the Chemistry Building on the campus of the University.of Iowa.
It was also used as a point source in neutron albedo studies in the same building. The source has been in storage for a number of years due to discontinuance of courses involving its use.
Currently it is in locked storage.in the basesment of the Radiation Protection Office Building on.the campus of the University of Iowa.
TECHNICAL QUALIFICATIONS Ol[ INDIVIDUALS' RESPONSIBLE FOR HANDLING THE SOURCES SOURCE Ap This is a change from the previous license request dated 2/25/80 in which we supplied the names of two specific faculty members as being responsible for conducting activities with Source A.
The restrictive specificity of limicing, to two individuals, the re.
sponsibility for use of a source used for instructional purposes for a period of five years (the term of the license)can severely limit
~
The University's flexibility of faculty assignments. Therefore we request:-
The activities involving Source A will be conducted by or under
.the supervision of individuals approved by the University of Iowa's Radiation Protection Committee and Radiation Protection Office Professional staff. The Radiation Protection Committee is established in accord with The University's Broad License #14-02938-07.

. organization is attached.
SOURCEj[
W. E. Twaler, Director of University of Iowa's Radiation Protection Office, is responsible for this source currently in storage.
Mr. Twaler's credentials are on file with this license and with the University of Iowa's Broad License #14-02936-07.
DESCRIPTION OF CONTAINMENT SOURCE A Source A is contained in a neutron howitzer. A description is on file with current license. The howitzer is used in Room 556A in Van Allen Hall.
SOURCEj!
Source B is contained in its criginalistorage container obtained with the source and is maintained in locked storage in the basement of the Radiation Protection Office Building.
RADIATION DETECTION INSTRUMENTATION The following radiation detection.and survey devices are available at The University for monitocing activities with sources:
TYPE OF INSTRUMENTS NUMBER AVAILABLE.
RANCE G-M(Portable) (E-520's) with HP 270& HP 190 Probes 4
0 -2R/hr PRM-6 with SPA-2 1
Neutron PAC-4G (Portable) 1 Alpha
-PAC-3G (Portable)
'l Alpha BAIRD ACCUCOUNT Alpha, Beta,GammaCounter 1
Alpha, Beta Gamma Calibration and checks of Radiation Protection instrumentation in accord with Broad licenses requirements.
PERSONNEL MONITORING
' SOURCE A
' Film badges will be issued to the principal. investigator who conducts
'the majority of activities with this source. He_will be aware, as must other listed instructors,of the necessity for and availability of
-film badge assignment for periods when teaching assistants and tech-nicians will be assisting with instructionalfactivities involving source manipulation.

'Page Four RE: Renewal Request-License No. SNM-204 Film badges, capable of detecting and measuring beta-gamma and neutron activities, are provided for short periods on a temporary and on call basis. The film badge service used is that of R. S.
Landauer Jr. & Company. Badges are routinely exchanged and reports provided on a monthly basis.
SOURCE B__
This source is in locked storage.
Current plans call for it to remain in storage until it is disposed of either by transfer or return to the original vendor.
SECURITY SOURCE A Source A is maintained in the padlocked " storage" position in the-neutron howitzer when not in use.
The keys; to the neutron howitzer padlock are maintained in padlocked storage cabinet inside Room 556A - Van Allen Hall.
Room 556A is normally locked when not in use and is a single access (one door - no windows) inner room as part of larger lab which is also locked when not in use.
Security personnel routinely check the. conditions of the locks during other than normal work hours.
SOURCE B l
Source B is maintained in its locked shipping container in the basesment of the Radiation-Protection Office Building on the i
University of Iowa campus.
The basesment area in which' Source B is stored also houses The University's calibration range which contains approximately 130 curies of Cs-137 as authorized by The University's NRC Licenses #14-02938-09.
l This basement storage area is accessible from two internal doors l
which are normally locked when not in use.
The external doors to the Radiation Protection O ffice are locked when the building is unoccupied (nights and weekends).
MANIPULATION & LEAK TESTING SOURCE A
-The manipulation of the sources will be accomplished by or under the supervision of the approved applicants and Radiation Protection
. Office personnel.- Due.to design of the howitzer, leak testing of the source can be accomplished either by removal or through an l
access port.
If and when the source.is removed for leak testing l
'it:will be handled with at least a two foot long handling tool l'
. hich is available.-

15 May 1985 USNRC Glen Ellyn, Illinois Page Five The neutron source will be leak tested quarterly. The test being a swipe test of the surface of the sealed source or surfaces of the device in which the scaled source is mounted or stored on which one could expect contamination to accumulate.
The swipes will be counted in the Alpha, Beta, Gamma counter in the Radiation Protection office which is capable of detecting the presence of 0.005 microcurie s of the activity on the wipe sample.
Records of leak tests results are maintained in units of micro-curies for inspection by the NRC. The NRC will be notified in event the'0.005 microcurie level of contamination is exceeded on the sealed source.
The howitzer proper and the inner room in which it is stored is appropriately posted with Radioactive Material signs and general radiation protaction operational procedures. Radiation emergency guidelines and specific information on the laboratory; e.g., names and phone numbers of cognizant individuals are cvailable. The room containing the neutron howitzer is on a routine survey list.
SOURCE B Source B is in storage and awaiting disposal. The room in which this source is stored is on a routine survey list.
The storage area and source are appropriately posted.
GENERAL All radioactive material, NARM, by product and SNM is under the purview of the University of Iowa's Radiation Protection Committee (see attachment).
ADDITIONAL INFORMATION CONTACT If additional information ir necessary to issue.a renewal of the subject license please feel free to contact G. T. Lonergan of my staff, phone number 319/353-3458.
