NUCLEAR REACTOR LABORATORY ANNUAL REPORT Fis. cal Year 1987-1988 l A.

SUMMARY

OF OPERATIONS 1

1. INSTRUCTIONAL USE - UW-MADISON FORMAL CLASSES Five Nuclear Engineering and Engineering Physics Department classes made use of the reactor. Fifty-three students enrolled in NEEP 231 participated in a two-hour laboratory session introducing students to reactor behavior  :

characteristics. Twelve hours of reactor operating time were devoted to this session. NEEP 427 was offered in the fall and spring semesters and had an enrollment of thirteen. Several NEEP 427 experiments use materials that are activated in the reactor. One experiment entitled "Radiation Survey" requires that students make measurements of radiation levels in and around the reactor laboratory. The irradiations in support of NEEP 427 and the radiation survey take place during normal isotope production runs, so no reactor time is specifically devoted to NEEP 427. The enrollment in NEEP 428 was nineteen, as it was offered in both semesters. Three experiments in NEEP 428 require exclusive c.se of the reactor. Each of these experiments ("Critical Experiment", "Control Element Calibration", and "Pulsing") was repeated thrse times during the year requiring a total of fifty-eight hours of exclusive reactor use. Other NEEP 428 laboratory sessions use material that has been irradiated in the reactor ("Fast Neutron Flux Measurements by Threshold Foil Techniques" and "Resonance Absorption"). These two experiments were repeated six times during the year. Twenty-five NEEP 305 students used the reactor to irradiate samples for a half-life measurement and for an experiment to measure the half-life of the longer-lived delayed neutron emitters. A class of five students completed the facility Reactor Operator Training program, which was taught during the spring semester as a four semester-hour formal course (NEEP 699/602). Each student performed reactor j startups (11 each), shutdowns (11 each), and other significant I reactivity changes. Two of these students have taken and  :

passed the NRC examination and are currently serving as 1 Reactor Op erators. The other three students could not be I l

certified as needing a NRC license, since their expected tenure at the University was not long enough. Individual one- i to two-hour sessions in the reactor laboratory were also held j for other classes.

4. CHANGES IN PERSONNEL, FACILITY AND PROCEDURES Changes reportable under 10 CFR 50.59 are indicated in section E of this report.

Operator Michael Rothenbuehler completed the requirements for his degree and left the university for employment elsewhere. Two students, Joseph Giebel and Michelle Parker, were trained and licensed during the year.

There were no significant changes to the facility or procedures during the year.

5. RESULTS OF SURVEILLANCE TESTS The only significant deviation from expected performance during surveillance testing was continued leakage from the reactor pool. Efforts to control this leakage are detailed in Section D of this report. ,

Inspection of underwater components showed no deterioration or wear.

C. EMERGENCY SHUTDOWNS AND INADVERTENT SCRAMS There were no emergency shutdowns during the year.

There were 11 inadvertent scrams or shutdowns during the year distributed as follows:

_2 Relay Scrams - 11/17/87, 12/04/87 --

with no changes in any measured parameter. These scrams are attributed to noise sensitivity of the period scram circuitry. The bistable that controls the relay scram does not trip in these scrams, but the solid-state relay controlled by the bistable picks up noise and drops out momentarily. Since the original solid-state relays employ zero-cross ~ing circuitry, the relay cannot pick up until the AC voltage drops to zero again. Since there was no need for the zero-crossing feature in this application, the relays were replaced on 12/22/87 with electrically equivalent solid-state relays that did not have the zero crossing turn-on feature.

1. 2 picoammeter range switch make-before-break feature malfunctioned, giving an instantaneous high output during upranging of the switch. Exercising the switch after the first occurrences had seemed to fix the problem, but the picoanneter was replaced with a spare after the third occurrence. The range switch in the original unit will be replaced.

05/16/88 -- After raassembly of blade to its shaft following the December maintenance chutdown the alignment of the armature with the magnet that picks up the blade assembly was not optimum. Since the core must be unloaded to realign the components of the blade, this was not repaired until the scheduled maintenance in June for pool rt lirs.

J Relay Scram - 07/16/87 --

core inlet temperature recorder slidewire cover fell off when recorder was closed, shorting out slidewire and causing an upscale deflection.

• It should be noted that six of the eight scrams were due to scran conditions not required by Technical Specifications (period scram and electronic scram), and none of the scrams excepting the AC power loss was due to any parameter being outside its normal operating range.

D. MAINTENANCE The rate of trater loss is detailed in Table 2 of Section F of this report. The levels of radioactivity in the pool water continued to be far below MPC for release to the environment. All leakage in Table 2 was ,

assumed to be released to the environment, although a large portion of the water leaked into the thermal column door tracks and was evaporated into the Reactor Laboratory.

During the annual maintenance shutdown in December,1987, the core was unloaded to the storage pit in the pool floor and radiation surveys were conducted within the pool. Dose rates were low enough that an operator with SCUBA diving experience was able to inspect the liner in the thermal column region. (Dosimetry worn by the diver indicated a total dose of 10 mrem.) As detailed in RSC document #428, the liner and weld appearance was excellent.

Table 2 shows that the leak again decreased markedly during the shutdown period and increased again as the weather warmed.

The underwater surveys indicated that, except for the regulating blade and fuel, radiation levels were low enough that the pool could be drained to permit finding and repairing the leak. A plan for the repair was approved by the Reactor Safety Committee at the May, 1988 meeting

UWNR Annual Report 1987-88 10 (RSC document #432) and was carried out in June, 1988. Fuel, the regulating blade, and neutron sources 'were transferred into the storage pit and covered with the shielded' cover.

Instrumented fuel elements, whose conduit extensions were too long to fit into the pit, were stored in a shielded single-bundle transfer cask (which was itself stored on the pool bottom). Hydraulic irradiation facilities were unloaded from the grid box e.nd placed at the pool bottom on the NE side of the poc1.

Pool water was incrementally drained into the 2000 gallon waste water hold tank and into a 27 foot diameter above ground swimming pool erected on the floor of the laboratory. ,

Pool. water level was lowered in 4-5 foot increments and the liner tested for leakage by applying 2-2.5 psi air pressure between the concrete pool walls and the pool liner. In addition, the water level was carefully monitored overnight at each level. Finally, dye injection between the liner and the pool wall was planned if the leak could not be located by the other methods.

Level change could not be used for leakage indication, since the lowered water level allowed the pool liner to relax away from the concrete walls, usually resulting in a level increatg overnight.

Air pressure checking revealed a single leak -- a crack in the pool wall in the form of an arc (0.5 inches long) about 9/32 of an inch above the top west corner of the thermal column. There was no evidence of corrosion, and no further leak indication as the pool level was drained to within three feet of the pool bottom.

With water at the lowest level the dose rate at the top of the pool was 10 mrem / hour, while at contact with the grid box the dose was 1000 mrem / hour.

Water level was increased to about 6 inches belov the leak in order to minimize dose during repairs. Dose rate in the area where the repair had to be made was20-100 mrem / hour under these conditions. The dosimeter of the person performing the repair indicated a total dose of 60 mrem.

Total dose during the entire drain / input / repair / refill was 100 mrem (per l dosimeter) for each of the two SR0 personnel who performed the work. I f

Quarter inch diameter holes were drilled at each end of the crack l and the cracked region was ground out. HIG welding was used to fill the '

grcund out area and to overlay that weld with three additional welds. The water level was raised and air pressure testing indicated the leak was sealed.

The pool was filled and operation resumed on 30 June 1988. There l has been no further indication of leakage since the repair.

SUMMARY

OF RADIATION EXPOSURE OF PERSONNEL (15 June 1987 -- 14 June 1988) ,

No personnel received any significant radiation dose during the ,

year. The highest doses recorded were 20 mrem whole body, 70 mrem skin dose, and 710 mrem extremity dose. Radiation doses continue to be low enough that 10 CFR Part 20 does not require we&cing of dosimetry even though facility policy requires dosimetry.

Routine radiation and contamination surveys of the facility revealed no problem areas, consistent with personnel exposure data cited above. ,

H. RESULTS OF ENVIRONMENTAL SURVEYS The environmental monitoring program at Wisconsin uses Eberline TLD area monitors located in areas surrounding the reactor !aboratory.

The table below indicates dose rates a person would have received if continuously present in the indicated area for the full year.
