Dear Mr. Stevenson:
i s
In reply to your questions for the license renewal of'SNM-180 docket #70-157 the following information is provided.
l.
The Radiation Safety Officer is a University staff position supervised by the Safety Engineer and responsible to the University Radiation Safety Committee which consists of faculty members.
a.
Duties of the Radiation Safety Specialist include periodic surveys and inspections, maintenance of radioisotope records and personnel exposures, and dispose of radioactive wastes. Other duties consist of periodic leak tests of sealed radiation sources, calibrate radiation detection instruments, act as a liaison for the University and state of Texas radiation license responsibilities, and help in the training of staff, preparations of procedures, and proper radioactive material handling.
b.
Education required is a Bachelor's degree in engineering, physics or related field.
Preferred qualifications re-quire advanced degree in health physics or radiological health or certification as a Safety Professional or Health Physicist.

Ye Mr.; Robert L. Stevenson' October. 10, 1980:
Page 2' c.
Experience required is three years work in radiation safety and/or radiological health.plus a thorough working' knowledge of Texas Regulations for Control of Radiation and supporting regulations issued by the USNRC. Preferred experieace' includes knowledge of particle accelerators and-nuclear reactors.
- 2. -All personnel pemitted routine access to laboratory facilities are monitored by film badges sensitive to beta, gamma, and neutrons.
Visitors and occasional experimenters are. routinely required to wear pocket radiation dosimeters (gamma sensitive) and record the observed doses. Laboratory personnel as_ a matter of practice supplement the -
filn badge monitor with a pocket dosfmeter (neutron or. gamma), when
. major radiation sources are handled or larger than normal doses ~ are expected.

The experience of Dr. Bauer consists of' undergraduate degree in physics and graduate degrees in engineering with the major. field of study nuclear engineering. Since June of 1978 Dr. Bauer has been an Assistant Professor with The University of Texas. Mechanical Engineering Department, teaching basic courses in nuclear reactor-theory, nuclear radiation detection, nuclear reactor operation and laboratory experimentation. Non-educational experience includes continuous part time employment as a research assistant in linear accelerator and nuclear laboratories since 1971.
Responsibilities during that period required the maintenance and operation of numerous radiation detection devices. More recent experience consists of acquisition of both reactor operator and senior reactor operator's licenses, responsibility for the UT TRIGA reactor operation, and training of three additional licensed operators.
- b. _ Dr. Klein's experience in the area of special nuclear material and radiation source handling is primarily educational in nature with a doctorate ~ degree in _ nuclear engineering from the University of Missouri. After three years of industrial experience, Dr. Klein has taught courses in nuclear safety and-power engineering since-1978 as an assistant professor of Mechanical Engineering at The University of Texas at Austin.

Experiments with the subcritica' assembly are' approved and supervised by the reactor laboratory supervisor.
In general these experiments are_ simple flux capping or irradiation type experiments.
In the event that a l_ess. routine experiment is' proposed.in which there might be additional questions of safety, the proposed experiment would be sub-jected to the same procedure and approval that a new reactor experiment-

tir. Robert L. Stevenson October 10, 1980
- Page 3 would require. By this method a safety evaluation review is obtained to control and monitor less routine use of the subcritical assembly.
.The procedure consists of proposed: experiment approval by the super-visor and reactor committee hfter proper evaluation of predicted exoeriment behavior. Subsequent analysis of the experiment's results allows the approval of the experinent as routine or requiring special consideration.
5.
The radiation detection-insttuments.available consists of routine survey GM(3)'and ionization chambers (2), BF3 tubes (2), fission counter (1), and other specialized neutron and gamma detection equipment routinely found in a nuclear reactor laboratory facility.
License requirements require the weekly monitoring of certain area radiation monitor set points and semiannual calibration of survey and area monitors. An air particulate detection system is also avail-able and is routinely operated at all times. Other than routine sur-vey instruments,-teveral special neutron detection systems are avail-able to be used as detectie monitors or for experimental purposes with multichannel analyzers, micro micro ammeters and other associated equipment. Routine survey instruments have sensitivities of.01 nr/hr to 5 r/hr (not on the same instrument). Neutron survey detection gen-with fell. scale ranges of 25 to 25,000 n/cm2-se(BF3 + moderator shield) l erally relies on a Nuclear Chicago model 2671 c.

Radioactive waste disposal. is handled separately through the Safety Office. Any waste cenerated from suberitical radiations is combined with reactor activation waste.
- The en:losed responses are recognized as brief but hopefully provide sufficient infornation to continue the SNM-180' license evaluation.
Perhaps.
it should be emphasized that the subcritical facility has essentially been integrated into the regular administrative and. physical structure of the UT TRIGA reactor facility license according to R-92.
Future intent is to include the SNM-180 material into the R-92 license, although that has not yet been initiated.
Sincerely, L
