UNIVERSITY OF WISCONSIN NUCLEAR REACTOR LABORATORY ANNUAL REPORT t 1

A.

SUMMARY

OF OPERATIONS

1. INSTRUCTIONAL USE - UN-MADISON FORMAL CLASSES Three Nuclear Engineering Depar tmen t cl asses make use of the reactor. . Forty-eight students enrolled in NE 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. NE 427 was-offered in the fall semester and had an enrollment of sixteen. Several NE 427 experiments use materials that are activated in the reactor.

! One experiment entitled " Radiation Survey" requires that students i make measurements of radiation levels in and around the reactor laboratory. The irradiations in support of NE 427 an'd the radiation survey take place during normal i sotope production runs, j so no reactor time is specifically devoted to NE 427. The enrollment i n NE 428 was twenty-four, as it was offered in both semesters. Three experiments in NE 428 require exclusive use of

the reactor. Each of these experiments (" Critical Experiment",

j " Control Element Calibration", and "Pul sing") was repeated four 1

times during the year r equiring a total of seventy-seven hours of exclusive reactor use. Other NE 428 laboratory sessions use i material that has been irradiated in the reactor (" Fast Neutron l Flux Measurements by Threshold Foil Techniques" and'" Resonance Absorption"). These two experiments were repeated eight times during the year. (Individual one- to two-hour sessions in the i reactor laboratory were also held for other departments on c ampu s . )

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

Licensed Senior Operator, Michael C. Jensen, completed his universi ty degree requiremen ts and accepted empl oymen t wi th a utility company. Licensed operator, John C., Mulvenna, left universi ty empl oymen t in June, 1983. Thi s l eaves a l i censed operations staff of three operators and four Senior Operators.

The audible portion of the evacuation alarm was replaced due to an upgrade of the building fire alarm system that resulted in a fire alarm signal similar to the evacuation alarm audibl e signal . The new audible alarm is a distinctive " Slow Whoop". The modification also provides a capability of paging and announcements over the alarm system should i t be desirabl e.

EMERGENCY SHUTDOWNS AND INADVERTENT SCRAMS There were no shutdowns initiated for emergency reasons during the year. The building evacuation alarm was spuriousl y ac tivated on 9/27/82 when ' buil ding el ec trical power was lost and subsequently restored. There were 8 inadvertent scrams distributed as indicated below:

)

2 Ichinae Dpacaloc Ecccc Icips 2/22/83--Trainee failed to uprange picoammeter in a timely fashion.

2/25/83--Trainee made a control blade withdrawal before log-N meter was fully on-scale. When the meter came on-scale a period trip resulted.

2 Spucious Icips 1com Eval Iamparaluce latiicatine Malac 2/10/83, 3/24/83--While operating at steady-state power level, fuel temperature meter 19MI initiated a trip without di scerni bl e upscal e meter movemen t . This instrument incorporates an upscale burnout feature and is sensitive to noise spikes on the AC power service. In both cases, the signal leads were tightened.

The meter was reading normally before and after each trip.

2 Encind Icips 12/2/82, 3/14/83--Period trip received during a startup after a prestartup checkout which included checks of the pulsing control circuits. Pulse mode operation and checkout includes automatic disconnection of signal input from the log-N period amplifier, removal of the high voltage from the detector, and shorting of the detector signal output to ground with subsequent automatic restoration of these conditions to normal.

Thi s compl etel y di scharges the signal cable and, at shutdown, the cable requires a long time to complete charging back to the normal condition. A l arge upscal e period meter deflection results, and the instrument trips. This problem does not occur during actual pulsing operation since detector current is large enough to eliminate this effect.

2 Ucise Spitas Caused.Icip Wilknut Lipscaia Ucuamaal on laskrumant 11/2/82--Picoammeter #1 trip -- no upscal e movemen t on pa #1 or #2.

4/4/83--Scram with no instrument indication when mode switch was switched from manual to square wave position. I t was not possible to get this behavior to repeat on subequent attempts to reproduce it.

D. MAINTENANCE Routine preventative maintenance kept equipment in good operating condition. The thermal column door seal (wea t h er s t r i ppi ng) was replaced due to normal deterioration.

E. CHANGES IN THE FACILITY OR PROCEDURES REPORTABLE UNDER 10 CFR 50.59 The pneumatic tube " receive only" station referenced in SAR Figure 22, page 2-40 and in the first two sentences of section 2.4.4 was removed on August 6, 1982. The switching terminal associated with this station was a recurrent source of air leaks, and it had not been used to receive samples in over five years. It is, however, possible that a need for the facility will occur in the future, so the removed equipment is being retained for possible future use.

F. RADIOACTIVE WASTE DISPOSAL

1. Solid Wasia No waste was transferred offsite during the year.

2. Liquid Wasta There were two liquid waste discharges during the year. The concentrations at discharge were bel ow MPC l evel s without considering dilution by the sewage discharge flow. Tabl e 1 details the discharges to the sewer system.

SUMMARY

OF RADIATION EXPOSURES (1 JULY 1982 - 30 JUNE 1982)

No excessive exposure of personnel to radiation occurred during the year. The highest exposure for any employee was 130 mrem whole body and 50 mrem skin which may be compared to the federally permissible dose of 5,000 mrem per year. The highest annual dose for any student was 40 mrem whole body and 90 mrem skin.

Routine radiation and contamination surveys of the f acili ty reveal ed no areas of high exposure rates or high contamination l evel s due to operation of the facility.

H. RESULTS OF ENVIRONMENTAL SURVET3 The environmental monitoring program at Wisconsin consists of thermoluminescent dosimeters (LiF TLD service from Eber l i n e) located in areas surrounding the reactor laboratory.

The tabl e bel ow lists doses for persons con tinuously in the area for representative dosimeter readings.
