1 I. INTRODUCTION During this reporting period (Sept. 1, 1977 through August 31, 1978),

the facility utilization experienced a 30% increase; essentiallf all the additional use was for nuclear utility " cold lic- ssing" reactor operations training. The utilization for University teaching and research was unchanged, maintaining the large teaching use with two reactor operations courses per year.

Fourteen research projects were conducted this year, again mainly for vacuum UV spectroscopy for the U.S. Army, BMD-ATC-O and activation analysis studies.

The complexity and time demand for administration continues to spiral upwards, keeping pace with the national trend. The number of regulatory inspections has doubled with the further separation of responsibilities within the Nuclear Regulatory Commission; the increase in security regula-tions (and emergency preparedness) created a new demand for manpower and funds.

Service-wise, the UFTR maintained high state-wide visibility with 49 tours and demonstrations conducted this year and national visibility with the research projects and the utility reactor operations training programs.

The re-licensing process contir 1s, with upgrading of most components of the Safety Analysis Report and the Technical Specifications requested by NRC. The UFTR is accelerating, with DOE support, the effort to change to the 4.8% UO fu 1 fr m the 93% enriched UAl fuel. Power upgrading to 2

500 kw thermal is expected to be done concurrently with the fuel change-over.

E III. FACILITY OPERATION I The UFTR, although still limited by neutron flux (at present power level) remains the most utilized teaching, training and zesearch tool of the Nuclear Engineering Sciences Department.

The teaching utilization remained high, with most of the time being taken by the two reactor operations courses, which use individualized

" hands-on" training at the reactor controls. Laboratory use was essen-tially unchanged.

The research utilization was essentially unchanged. Two three-weeks reactor operations training programs were conducted during the summer of 1978 for the Louisiana Power and Light " cold-licensing" operators. These programs, using " hands-on" reactor operations training increased the reactor utilization some 30s from last year.

Changes in the reactor operations and associated procedures have been made to increase efficiency, safety and security.

Shown in Table I is a summary of the reacto utilization ror this report period. The list categorizes the twenty-eight ( .ferent research projects and the teaching and training activities. The tota. reactor on-time was about 900 hours0.0104 days <br />0.25 hours <br />0.00149 weeks <br />3.4245e-4 months <br />, with 542 man-hours employed on establishing the e::periments, con-ducting the teaching and services, running and maintaining the reactor.

Table II summarizes the different categories of reactor utilization, irradiation time, teaching and training, checkouts, calibration and experi-mental set-up services.

Detailed in Table III are the monthly and total energy generation. The UFTR generated 26.376 Mw-hr of energy during this reporting period, essen-tially unchanged from last year's. Table IV shows the reactor full power I

I running by month and total.

Described in Table V are the reasons and dates of unscheduled shut downs and re,trtable incidents. A release of gaseous tritium into the reactor cell, which exceeded MPC in the cell environment for a few hours was reported during this period. No significant amount of tritium intake was detected in any workers and no hazards were created for the general public.

A significant m unt of activities were conducted during this year to increase the effectiveness of response at the University, city, county and state levels associated with emergency situations (fire, radiological and security related).

12 IV. MODIFICATIONS TO THE OPERATING CHARACTERISTICS OR CAPABILITIES OF THE UFTR I

Effective January 19, 1978, the backup secondary cooling water supply from the city water is equipped with a low flow sensor. The low flow sensor initiates a reactor trip and is more indicative of system performance than the pressure switch which the low flow sensor replaced.

Effective June 2, 1978, a Watts Series 900 reduced pressure principle backflow preventer was installed in the city water supply line used for UFTR demineralized make-up water and as auxillary secondary cooling water.

The installation of the backflow preventer will insure that the city water system cannot become contaminated through either backflow or back siphonage.

2. December, 1977 - One experimenter received 30 mrem gamma whole body dose principally due to the handling of I irradiated experiments.

Dosimeter exposure measurements for visitors to the UFTR were all less than 5 milli-Roentgen each for this reporting period.

For this course, students are assigned in pairs to spend two hours weekly in the UFTR cell performing reactor startups, shutdowns, operacions at power, as well as tests and calibrations of reactor systems and nuclear instruments normally done as routine checkouts. This course is recommended for senior undergraduate and graduate students in Nuclear Engineering. All student acti-vities in the UFTR are performed under the direction of a licensed Reactor Operator or Senior Reactor Operator.

21. Principles of Nuclear Reactors, NES 400 - Dr. J.A. Wethington and 24 students * (Nuclear Engineering Sciences)

This introductory course for non-nuclearmajors utilized the reactor for a reactor power demonstration.

22. UFTR Reactor Operator Training - UFTR Licensed Staff To supplement the UFTR operating staff and increase the operating capa-bility of the reactor, student personnel with prior military nuclear experience are given qualification operational training under the direct supervision of licensed operators. This training encompasses routine operations, routine checkouts, scheduled repetitive calibration checks, participation in drills, participation in maintenance activities, testing on understanding and profi-ciency of items such as operating procedures, technical specifications, routine administrative matters, and applicable rules and regulations.

The personnel chosen to receive this qualification training are selected v

. 23 with a view toward the UFTR receiving a maximum length of service from them after they have received their operating licenses.

This past year D.B. Carter was given consideration for his long and continuous association with and utilization of the UFTR Cor research and was examined by the N.R.C. for his Reactor Operator license on August 3, 1978.

24. Reactor Operator Training: Louisiana Power and Light Company - Training Staff: Dr. N.J. Diaz, UFTR Staff, Dr. E. Dugan, W. Vernetson**, W. Kerrick",

T. Kanellopoulos*, H. Norton (Radiological Safety Officer) , T. Bauer (Radia-tion Control Officer)

Twenty-four (potential rc *.ctor operators and supervisors) of Louisiana Power and Light Company received intensive training at the UFTR in reactor physics, instrumentation, operations, and radiological safety. The program consisted of two duplicate three week sessions with approximately half of the-trainees on campus at one time to maximize time spent on a one-to-one basis between the UFTR staff and LP&L staff. Reactor operations labs gave each trainee extensive hands-on training through all phases of reactor operation from sub-critical to power with emphasis on the ability to interrelate reactor systems during both normal and abnormal conditions to insure reactor safety.

25. UFTR Instrument Alignments and Calibrations - UFTR Staff Performed calibration of primary coolant flow meter and temperature re-corder and calorimetric run made to calibrate and align the nuclear instruments.
