SUMMARY

l This report details the pertinent activities related to j the Texas A&M University AGN-20lM training reactor facility operated by the Department of Nuclear Engineering during the period June 1, 1980 to May 31, 1981. Furthermore, it is in-tended that the contents of this report comply with the re-quirements of 10 CFR 50, Section 50.59 (b) and Appendix A, Technical Specifications, of the NRC license R-23.

The utilization of this facility continues to be similar to that of previous years. The general categories of uti-f lization for this past year were support of Nuclear Engineer-ing courses, operator training, and preventive maintenance.

Nuclear Engineering courses supported during the past year l were:

I l

ENGR 10lG Engineering Analysis l

NE 405 Nuclear Engineering Experiments

[

NE 679 Practical Applications of Radiological Safety I During normal preventive maintenance, malfunctioning components were replaced as detailed in Section 4. Facility modifications and component replacement performed during j this reporting period do not involve unreviewed safety ques-tions and are not expected to adversely affect the safe operation of this facility.

The results of all maj or parameter surveillance tests are shown in Table I.

- - _ ----- - - . . . - = - ]-- ~ Y -- = - - = -=- .- =-- ~ ~'-~~~-

perfod are summarized as follows:

(a) 7/18/80 - Channel #2, low level trip, noted l

inoperative during prestart-up checks. Optical trip, bulb was found burned out. Replacement was made using a spare. The channel was tested and found satisfactory.

(b) 10/17/81 - Channel #2, calibration drifting as noted in control rod readings out/in. Replaced calibration battery. Channel #2 cctested satis-factory.

(c) 1/13/81 - During re-energizing channel #2 after the Chr d stmas holiday it m:1 functioned. Several tubes, V-4, V-5, V-14, V-17, were found defective.

After replacement of tubes channel #2 functioned satisfactorily.

(d) 5/7/81 - De-energized Channel #2 due to oscillations k and spurious trips. Repairs were not made since Reactor Supervisor was not available.

l (e) 7/20/81 - Channel #2, repaired and placed back in service. Repair consisted of replacing V-15.

f The corrective maintenance and component replacement performed during this reporting period have no impact on the l safe operation of the reactor facility and do not change the description of the facility as submitted in the license appli-cation and amendments thereto.

I S. (a) REACTOR MODIFICATIONS No modifications were made to the Texas A&M University AGN-20lM reactor during this reporting period.

5. (b) CHANGES TO PROCUEDURES.

No procedure changes have been made during this reporting period, o

5. (c) NEW EXPERIMENTS OR TESTS No new experiments or tests were performed during i this reporting period.

6.

SUMMARY

OF SAFETY EVALUATIONS No changes, tests, or experiments were performed subsequent to 10 CFR 50 paragraph 50.59, during this reporting period; therefore, no safety evaluations were required.

7.

SUMMARY

OF RADI0 ACTIVE EFFLUENT RELEASES '

No liquid or solid radioactive waste was released during this reporting period.

8. ENVIRONMENTAL RADIOLOGICAL SURVEYS No environmental radiological surveys were performed outside the facility during this reporting period.

[

9. RADIATION EXPOSURE No reactor facility personnel or visitors received radiation exposures greater than 100 mrem (50 mrem for persons under 18 years of age) during this reporting period.

10. REACTOR SAFETY BOARD ACTIONS (a) 1/23/81, The Reactor Saf ety Board perf ormed the yearly review of the AGN-201M Facility Security Plan. The board agreed that the plan was still satisfactory for its intended purpose.

i (b) 1/23/81, The Reactor Safety Board reviewed audits previously performed.
