Dear Dr. Mallet:

Pursuant to our recent telephone conversation enclosed is additional information in support of our request to renew NRC License SNM-490. Our control number is 06678.

Please call again if additional information or clarification is needed.

Sincerely, S'A Kenneth M. Fritz Radiation Safety Officer University of Cincinnati KMF:bb Enc 1:

1.

Users of the Pu-Be sources are Messrs.' Boeing and Emmerich and Dr. Anno'.

Their training and experience is listed in'our correspondence of July;26,'-

1982. As 'also stated in this July 26' correspondence, no students will handle the sources. Any' new personnel before being' designated as users will be,

-i trained in the handling procedures;by one or more of=the present' designated i

users if they lack handling experience.

In -addition, they.will be required-to complete the University radiation safety. course.if' deficientiin radio-nuclide training and experience. This judgment will be made-by the Radiation Safety Officer:after examining the credentials ~of the11ndividual'and reviewing recommendations of the present designated users'. -

2.

Calibrations of alpha, beta and gamma! survey; instruments are conducted by Radiation Safety Office personnel using-the procedures' enclosed as part-

.of the. July 26 correspondence. Calibra' tion of-these' instruments is conducted by Mr. Lee Ashcraft (Environmental Technician) or Ms. Carla Chifos (Deputy Radiation Safety Officer), both of whom have several~ years experience in the calibration of radiation survey instruments. 1All meters are calibra'ed-t at six month intervals.

The neutron meters (Eberdine PNC-1 and PNR-4) are also calibrated at six month intervals by'one of the authorized users with the following proce-dures: a 1 Ci Pu-Be source is placed at the bottom 'of hole #1 of a neutron howitzer.

The BF-3 detector is placed at the bottom.of hole.#4; A reading.

~

of 180 EPM (events per minute) is, measured. The.1 Ci source is removed and-a 4 Ci source is placed at the bottom'of hole #1 with the BF-3 detector:again at the bottom of hole #4. A reading of 1000 EPM. should be measured. ' With the 4 Ci source still in hole #1, the. BF-3 detector 'is placed at.the bottom of hole #2. A reading of 130,000 EPM should be meas 6 red.. Finally,>the 4 Ci source is removed. and a 1 Ci source placed' at ' the bottom of ; hole #1 with the BF-3 detector'still in hole #2.. A reading ' of 32,000 EPM should be measur-L ed.

The meter is adjusted, if necessary, to obtain these-readings.

PNR-4 Meter. 1 C1, 2 C1, 3 -Ci and 4' Ci-Pu-Be sources are pla'ced.against a marked point on the detector and readings of f125, ' 230, 360 and 500' MR/HR, respectively should be measured, Figure 2.

Then.a 4 x 8 x 2 inch parafin-block is placed against the marked spot on the~ detector and a 1 Ci Pu-Bei.

source is placed against the parafin blocks. A reading of 12.5 MR/HR should be measured. The meter is adjusted, if necessary,' t'oJobtain these readings.

3.

Responsibilities and duties of the Radiation Safety Of ficer as stated in our Radiation Safety Manual are enclosed..

4.

If the sources are to be disposed, they will either'be returned to-the manufacturer or disposed at an NRC approved site as radioactive waste. Any-.

l activated samples or targets will either be hcid until they decay 'to background if only short half lives are' present or they will be disposed as radioactive-1 waste at an approved burial site.

5. and-6.

Instructions-in the use of these sources.will.be given by one of. the l

authorized users' (Boeing, Anno or Emmerich). - ' At no time will anyone except an authorized user, the RSO or the DRSO-(Deputy) handle'or transport these' sources.

Enclosed is a copy of the curriculum of classroom instruction provided by the

~

. Radiation Safety Office. Students'are typically Nuclear Engineering graduate j

students. Additional, supporting information has been ~given in answer to question 1.
