Docket No. 50-192 AUG 0 91985 Dr. Dale Klein Nuclear Engineering Program College of Engineering University of Texas Austin, Texas 78712

Dear Dr. V.lein:

SilBJECT: REQUEST FOR ADDITIONAL INFORMATION ON THE UNIVERSITY OF TEXAS (UT) DECOMMISSIONING PLAN The staff has initiated the review of the UT Deconunissioning Plan submitted by letter dated May 3,1985.

In order to proceed with the review, we require the additional information indicated in the enclosed set of questions. Please submit your response by September 9,1985.

If you wish to discuss the questions, please contact our Project Manager for your facility, Hal Bernard, at (301) 492-9799.

Sincerely, "The reporting and/or recordkeoping requirements containod in this letter affect fewer than ton respondents ;

therefore, OM3 clearance is not roquired Cecil 0. Thomas, Chief under P.L.96-511. =

s REQUEST FOR ADDITIONAL INFORMATION DECOMMISSIONING PLAN OF THE UNIVERSITY OF TEXAS General (1) During demolition boring and other operations that could be cause for dispersion of radioactive dust, dust levels could be significant in

~~

occupied areas. Although ventilation and confinement barriers will be provided, please discuss your plans for monitoring for airborne radioactivity on a grab sampling and continuous basis. Additionally, please address the respiratory protection program you will use if results of this monitoring warrants it, including training and fitting of personnel.

(2) Although not addressed in the Deconsnissioning Plan, please discuss your plans for bioassay of workers to assure the adaquacy of your airborne radioactivity and respiratory protection programs.

(3) TLD devices are normally used in parallel with pocket chambers to monitor personnel exposures. Please describe how personnel exposure will be tracked by the health physics group to ensure that daily exposure summaries are reviewed so that permissible limits are not exceeded.

s (4)

In the 1984 Annual Report of the University of Texas, it is noted, on Please page 20 Table 8, that film badges are used to measure doses.

clarify whether these personnel monitoring devices will also be used in the deconnissioning operation.

If so, were they inadvertently omitted in Table 2.2 of the Deconnissioning Plan.

Specific Questions (1) page 1-11 The 2nd paragraph alludes to pool coolant radioactivity 24 indicative of Na activity. Please cite the radionuclides 24 in the coolant and explain the origin of the Na activity.

Additionally, discuss the localized points within the facility where "significant concentrations may be present",

and their order of magnitude.

Although the responsibilities of the health physicist are (2) Pg 1-24 defined, his qualifications are not given in this report.

Please describe the experience of all health physics personnel who will implement the radiation protection program during the deconnissioning. Please include contractor health physicists, as required.

Does the specification " Gamma measurements will be made (3) Pg 3-9 Section 4 along a single straight line....." imply that only one sector of 4n around the facility will be monitored i

to determine outdoor radiation levels from effluent release pathways? Please describe your plans for monitoring other sectors where airborne radioactivity or liquids may have been cause for surface or under-ground contamination.

If these pathways have never been cause for need to monitor, please so specify with relevant justification.

(4) Pg 3-9 Please describe the pathways that could be cause for Section 4 concern for contamination in the soil from the decom-missioning operation to warrent need for making back-ground contamination level measurements.

(5) Table 2.2 The table of Radiation Survey Instruments lists "TLD reactor exposure bulbs and mini-rods" as instruments to be used during the decommisioning. Please explain 1

what these devices are, their range and sensitivity, and how they are calibrated and read out.

(6) Pg 7.1 The proposed radiation survey plan states that a temination radiation survey will be conducted that will satisfy the NRC acceptance criteria of 5 uR/hr above background at 1 meter. Please address the instrument

-4 that is planned to be used for this measurement and its characteristics (if it is not a pressurized ionization chamber) that would ensure its reliability to measure the dose rate independent of gamma-ray energy.
