February 28, 1933 U.S. I'uclear Regulatory Cocr.insicn, Region II 101 bhrietta Street , N.W. 1 Atlaria, Geortla 30303 Refemnce: Do &et 50-160; License R-97 Gentlemen:
Parsuent to section 6.7a of the Technical Specificatf orc fer the Georgia Tech Research Reactor (license R-97), the co lla.:Irc an-nual report is subnitted. The reporting period is J:enuar/ 1,1979 through Decerter 31,1979 (calender yea" 1979). Tre designation of the paragraphs follow the title and order of Section 6.7a of our Technical Specifications.
- 1. Operations Sunr:nry
- a. Chanres in Facility Ibsien here wem no reportable changes in facility design d tring this reporting period.
- b. Perfornnnce Characteristics During the reporting period, the reactor was operated at power levels up to 5000 kd(t) using a 17 elecent core. Fuel perforrance has continued to be natisfactor*/
with no known problems.
- c. Chances in Operating Procedures (Safety Palated)
I Were were no reportable changes in operating procedurec during the reporting period.
- d. Pesults of Surveillance Tests and Inspections The surveillance tests and inspections of the facility required by the Technical Specifications were performed.
Results of each of these tests and inspections are avail-able at the site for review.

U.S. Nuclear Regulatory Comission, Region II Page 2 February 28, 1980
- e. Changes, Tests and Experinents Approved by USNRC i
Bere were no changes, tests or experinents that required the approval of USNRC pursuant to 10CFR 50.59 (a).
- f. Changes in Plant Staff and Corrnittee Membership he curmnt plant operating staff is as follows:
Dr. M.V. Ihvis, Director, Nuclear Research Center Mr. R.S. Kirkland, Associate Director and Reactor Supervisor Mr. R.S. Kirkland, Acting Reactor Engineer Mr. R.M. Boyd, Radiological Safety Officer he current organization of the Nuclear Safeguards Caxtittee is as follows:
Fr. R.M. Boyd Dr. R.N. FacDonald Dr. M.V. Davis Dr. D.W. Fartin Dr. B. Kahn Dr. J.H. Russell Mr. R.S. Kirkland Dr. J.W. Poston
- 2. Power Generation Fbr the period January 1,1979 throu@ Decenter 31, 1979, the total power generation of the reactor was 837 megawatt hours.
3 ShutdowTis During the reporting period, there were 24 unscheduled shutdowns of the reactor. Rese are tabulated in Table I as to the cause and pmventive action taken.
- 4. Fhintenance 6afety-related systems and components)
In July and in November, repairs were made to the regulating rod drive mechanism. he repairs included replacenent of the right-angle gear drive and replacenent of a broken shaft key.
In Septenber, mpairs were made to the TRA-D1 mcorder. A broken lead was replaced and a lead length adjust potentiometer was cleaned.
In October, the purification pump FD-4 failed due to excessive bearing wear. In Decenber, companion pump FD-3 failed for similar reasons. New bearings and a replacement rotor were installed in MD-4 and the unit returned to service.
In November, the motor and bearings for the Kanne circulating punp were mplaced fouowing failure of the unit.

U.S. Nuclear Eegulatory Comission, Region II Page 3 February 28, 1980 In December, the uncompensated bn cha2er position H-18 was removed in an effort to locate the source of the many Ion Chamber Voltage Scrams. Evidence was found of loose or broken pin connections at the high temperature cable /
. chad er connection. A replacenent chamber was installed ard the high temperature cables were re-worked.
5 Changes, Tests and Er.periments Without Prior USNRC Approval.
During the reporting period there were 69 approved experiments for the Georgia Tech Research Reactor. Each of these was evaluated prior to its approval with regaM to Section 3.4 of our Technical Specifications. RecoMs of each experiment are available at the site for review.
