ANNUAL REPORT A.

SUMMARY

_OF OPERATIONS

l. Instructional Use - UW-Madison Formal Classes Three Nuclear Engineering Department classes make use of the reactor.

[ The 45 Students enrolled in NE 231 participated in a two-hour experiment designed to acquaint students with behavior characteristics of a nuclear t

reactor. Thic experiment was repeated four times. NE 427 had a total en-rollment of 29 students as 't was offered in both Fall and Spring semesters.

Several NE 427 experiments use materials that are activated in the reactor while one experiment entitled, " Radiation Survey' requires that students I

make measurements of radiation levels in and arounc ;'ie reactor laboratory.

l NE 428 makes extensive use of the reactor as it is taught during both I

semesters and summer school. 32 students completed NE 428 during the fis-cal year. NE 428 incorporates three experiments (" Critical Experiment",

" Control Element Calibration", and " Pulsing") which require exclusive use of the reactor. These experiments were repeated f *ve times for NE 428 classes. Two additional 428 experiments (" Fast Neutron Flux Measurements by Threshold Foil Techniques" and " Resonance Absorption") were repeated ten times each during the year. These experiments use the reactor for activation of foils for the measurements.

At least one session in the reactor laboratory was included in the courses of tne Departments of General Engineering, Metallurgical and Mineral Engineering, Physics, Chemist.y. Journalism, and Mechanical En-gineering. In addition, laboratory personnel presented formal lectures for Introductory Chemistry ar.d Physics classes on the general subject of nuclear power and with specific applications to the Three-Mile Island ac-cident.

I 2. Reactor Sharing Procram

^Q3 The work by the University of Minnesota-Duluth group c(b 7sta ff[mes bers and 2 graduate students) on identificc. tion of copper ar.d tin arti-facts and nres by multielement Ins;rumental Neutren Activation Analysis 1

, continued. Personnel from the University of Wisconsin-Stevens Point pet-ticipated in the Reactor Sharing Progrcm two ways. First, during the summer, they brought a group of 25 high scicol students enrolled in a summer program for a reaccor operation demonstration. In addition, during the serester, a group of s':udents (5 students, I staff member)

came to our laboratory and participated in the reacter operation demon-stration previously developed for our flE 2.}! classes. 12 students from the University of Wisconsin-fiilwaukee spent th ee hours in a laboratory session on Instrumental fleutron Activation Analysis as a part of their course number CE 891-3. A group of 8 Advanced Physics students from Lcercil College attended a 3-hour fleutron Activation Analysis laboratory at ou. facility. 8 students from Beloit College attended a reactor opera-tion demonstration. Finally, '2 students from the University of Wisconsin-Platteville attended a 3-hour fleutron Activation Analysis laboratory session.

3. Utility Operating Personnel Training Two-week research reactor familiarization courses were held for two groups of 6 trainees from Cleveland Electric Illuminating Company. The 12 people trained will be part of the operating staff of the two-unit BW'i Perry Generating Plant. The program occurs early in the academic training of individuals who are car.didates for operator and senior operator licens-ing and who do not have considerable previous nuclear training. Most of the students in the two groups are persons with operating experience in

%nventional power plants. The progras acquaints the students with reac-tor kinetic behavior, instrumentation, operating practice, and general tech-niques involved in dealing with radioactive materials. The session at Wisconsin is essentially the laboratory portion of a training program con-ducted for Cleveland Electric Illuminating by the General Physics Corpora-tion.

4. Sample Irradiation and fleutron Activation Analysis Services During the year, 4,803 samples were irradiated. 1217 of these sam-pie irradiations were for 15 c;.iutes or less, while the remainder accumu-lated 9,121.95 samnle hours of irradiation. The irradiation work can be further classified into 862 irradiations and 447.7 irradiation space hours.

3,637 of the samples irradiated (76f of the total) were irradiated as part of the laboratory's fluetron Activation Analysis Service in which samples are submitted by outside users for subsequent sample preparation and analy-sis by Instrumental fleutron Activation Analysis.

A listing of the individual groups for whom irradiations were per--

formed follaws. In this listing, information is supplied on the object of the research, personnel involved, and sponsoring organization where known.

5. Chanr'es in Personnel, Facility, and Procedures Don,'l E. Range, a full-time reactor operator / technician joined the staff during the summer of 1978 and is presently licensed as a reactor oper-ator. Three part-time employees, Herbert O. Nelson, Michael C. Jensea, and Jeffrey P. Ladewig have been licensed as operators during the year.

No reporta'. Changes in the facility as described in the Safety Ant.-

lysis Report were made during the year. The refueling of the core toward a l full FLIP core was continued. The last run with a mixed core was completed on 14 June 1979. Six additional FLIP bundles were received on 13 June 1979 i

and loaded by Critical Experiment into 'he core on 15 June 1979. The full FLIP core was critical at 1432 on 15 June 1979, on 18 bundles, with an ex-cess reactivity of .08% and a shutdown margin of 7.5%. The core was loaded to a 21-bundle all-FLIP configuration which was checked for compliance with Technical Specification requirements on shutdown margin and transient rod worth and then operated at power in order to bring the new FLIP fuel to self-protecting levels. This was necessary to assure that the license requirement limiting quanti +y of non-protected 70% enriched fuel was met. An additional shipment of FLIP to complete the 25-bundle FLIP core i', expected the last week in July, and a full test program will then be completed. A complete description of the reloading and test program on the full FLIP core will be issued subsequent to completion of the test program.

Only minor changes to procedures were made to update procedures for current conditions. None of the changes are reportable under conditicns of 3 7" b

. !; 7o

the Technical Specifications. Some changes were made in the 130 series of procedures (dealing with sample irradiation) in order to conform to the changes in campus requirements for transfer of nterial to the University's broad license. The changes require a -lephone check of the current status of the authorization of individuals to whom .eactor-produced radioisotopes are to be transferred. In addition, the i..dividual picking up a sample will receive a copy of the irradiation request, and another copy of the irradia-tion request with information on Ate and time of the irradiation will be submitted to University Health F. 3 cs as a receipt document.

6. Results of Surveillance Tests Surveillance tests and inspections during the year revealed no pro-

, blems in safety-related systems. Surveillance of licensed operator per-formance under the Operator Proficiency Maintenance Program showed no de-ficiencies on written examinations. One operator was suspended from li-censed duties because of an unsatisfactory evaluation in oral exanination.

He is required to undergo additional training and at least ten reactor startup cycles before Se may be re-evaluated and restos ad to operating status. .

C. EMERGENCY SHUTDOWNS AND INADVERTENT SCR/.MS There were no emergency shutdowns during the year. There were, how-ever,13 inadvertent automatic shutdowns (scrams). Nine of these were due to operator errors (12 utility operator trainees and 4 UW trainees during the year). Two were due to noise spikes from bumping control element drive or instrument channel cceonents while loading samples, and two were due to instrument failure. A de';ription of each of these events is inc"cated be-low in chronoligical or .er. On one additional occasion (24 October 1978),

the cperator on duty manually scrammed the reactor when the log-N period channel indication drifted downscale after reaching a level power. An in-vestigation indicated the insulation resistance of the detector had de-creased due to moisture buildup.

20 July 1978 - Tra' ne= turned picoammeter #1 range switch to a lower range while intending to switch to the highest range to fire a pulse.

15 September 1978 -- Trainee failed to uprange #1 picoammeter in a timely fashion while increasing power level.

15 September 1978 -- Control blade #1 drive bumped while loading a sanple into irradiation position. The blade was knocked loose from its magnet.

10 and 12 January 1979 -- Trainee turned range switch on #1 picoam-meter in wrong direction while increasing power level.

16 Janua.y 1979 -- Period trip due to trainee increasing power level too rapidly as log-N period channel came on scale.

18 January 1979 -- Trainee failed to uprange #1 picoammeter in time while increasing power level.

1 February 1979 -- Trainee failed to uprange #2 picoammeter in time while increasing power level (had changed #1 in time).

6 February 1979 -- Period trip from noise induced in channel when cables were bumped during sample loading. A second trip from the channel the same day while level at full power led to further investigation which showed a decrease in insulation mistance at the input to the instrument.

This channel becomes sensitive to ground loop noise when the insulatinn resistance between electrodes or between the detector can and the water-proof housing decreases below about 10 ohms. In this case, the insula-Lion resistance of the log diode fe' dback element had decraased to about 10" chms, causing extreme noise sensitivity.

ut i 79b

_g_

16 March 1979 -- Trip from both #1 and #2 picoammeters when operator failed to uprange in time during a rapid power increase.

5 April 1979 -- Trip from both picoammeters when setting up for pulse mode. Reactor was level at 300 watts with all permissives for pulse mode met. The operator was preparing to initiate a pulse. The pulsing switch was stuck in the actuated position because of mechanical binding. When the mode switch was turned into square wave position (intermediate between manual and pulse positions), the transieat rod fired, initiating the pulse be_ fore the power level scram was defeated ~ by the mode switch and pulsing interlocks. The switch housing was modified to prevent recurrence.

,, 14 June 1979 -- Operator failed to downrange picoammeter #1 in time while increasing power level because his attention was on period channel at that time.

It should ce noted that #1 picoammeter is involved in most of the '

operator error trips. This is not due to a deficiency in that instrument but to the fact that it is usually the first range switch to be switched by the operator.

D. MAINTENANCE OPERATIONS Ordinary preventative maintenance was performed on equipment and re-sulted in acceptable performance except for two items of corrective main-tenance on the log-N period channel detailed in section C above. There were no reportable maintenance operations.

E. CHANGES IN THE FACILITY OR PROCEDURES PURSUANT TO SECTION 50.59 0F i0 CFR PART 50 There were none.
