INTRODUCTION 1

The Nuclear Science Center is operated by the Texas Engineerin6 1

Experiment Station as a service to the Texas A&M University System and the State of Texas.

The facility is available_ to the University,

' organizations and individuals.

The facility operating license, R-83 I

issued by the U.S. Nuclear Regulatory Commission, currently extends through March, 2003, a

This report has been prepared by the staff of the Nuclear Science l

Center of the Texas Engineering Expee;. ment Station to satisfy the reporting requirements of Technical 2,pecification 6.6.1 to the facility operating license R-83 and of U.S 30E Contract

1. DE-AC05-76ERO)4207 ( formerly EY-76-C-05-L ;i) and 10CFR50.59 The report covers the period from January 1, 1989 through December 31, 1989.

Total operating hours of the reactor increased over '1988 values.

The total experiment hours were approximately the same as 1988 with a a

decrease in sample irradiation hours.

Beam port and irradiation l

experiments continued to increase and there_was a decrease in irradiation cell experiment hours compared to 1988._

These changes in utilization were due primarily to the characteristics of the experi-ments performed.

Commercial utilization and the number of tours increased.

Core VIII-A, which has been operational since March 1986, was I

used throughout 1989.

Pulse operations were continued at a low level in 1989 with a trtal of 40 pulses ($61.48 total pulse reactivity) executed.

As in the previous few years, pulsing operations were re-stricted mostly to calibrations and laboratory demonstrations.

There were no changes made to the site area during this reporting-period and no changes were made~to the security or emergency systems.

FACILITY OPERATIONS A.

Facility Improvements New Facility Air Conditioning Units Two new smaller air conditioning chill water cooling units were installed as replacement of an older unit that could not be repaired.

B.

Improvements to Reactor Systems and Experimental Facilities Miscellaneous Equipp n t 1ontrol Drawer This drawer was completely rebailt with new components and a new face format.

The drawer still controls the following devices:

lower research level access controls, front gate, C-2 warning devices, cell /

pneumatic exhaust fan, watt shutter indications, and operator status board.

Facility Air Monitor Meters New FAM meters were installed as replacement of meters in the reactor control room and the reception room.

The old meters were hard to find, very expensive, and difficult to calibrate.

The new meters are better in all of these respects.

New Switches for Reactor Console Pump switches were replaced and solid state control circuits provided for water system control.

These type switches have reduced electronic noise sources considerably.

As a result, there have been fewer spurious signals to the reactor instrumentation.

A heavy duty reactor console power switch was installed as a replacement to improve' reliability.

Diffuser Pump and Transient Rod Surge Tank Blowdown Piping Rearrangement The diffuq r pump piping and transient rod blowdown piping were rearranged under the reactor bridge to make room for the new east face irradiator.

Additional Rotisserie Irradiation Device Storage To expand the capacity of rotisserie storage a new rack-was installed on the north pool wall.

The rack has storage positions for 12 rotisserie irradiation devices.

12 s

Additional Sump Pump Strainer and Blow Down f

A new strainer and strainer blowdown piping were installed para 31e', to the old sump pump strainer and blowdown.

These strainers prevent solids from reaching the liquid waste holdup tanks.

The blowdown piping enables the strainers to be cleaned periodically.

Self Adjusting Skimmer Head The old skimmer heads would not work well with different pool levels due to the difficulty in adjusting their heights.

A new single skimmer head was designed to be self-adjusting and is working fine.

Cross-Connect Valves in the Facility Air Monitoring System New valves for this system were added upstream of the main flow control panel.

These valves allow a cross connect between air sampling locations and detectors.

In case a detector normally required for operations is out of service, the appropriate sampling location can be changed to another operable detector.

Beam Port #1 Collimator A series of cylinders of graphite, borated parrafin, lead, boroflex, and concrete were placed inside Beam Port #1 to act as a collimator of neutrons.

This creates a narrower and more con-trollable neutron beam for experiments.

C.

Operational Problems Reportable Occurrence 89-01 Adjustment of Linear Channel Compensating Voltage There was a requirement to adjust the linear channel compensating voltage due to a significant increase in scheduled reactor operating hours.

When additional night shift operations were added, the increase in core power history caused the startup gammas to be more significant at low power levels.

The compensation voltage was reset and normal readings returned.

All required tests were perfornied and the instrument was returned to normal operation.

Beam Port #1 '.iater Shutter Repair

.A down leg of the water shutter was leaking at the union with the beam port piping.

The.down leg leak was repaired using a saddle at the union.

A gasket was used to seal the saddle to the beam port pipinc.

The saddle is held in place against the beam port piping with two stainless steel strapes.

This design has performed well since installation.

i

13 Failure'of Compressed Supply Air Piping Compressed air supply piping between the demineralizer room and the' tunnel area suffered a-corrosion stress fracture.

Galvanized-piping was usedsfor replacement which has a greater resistance against' moisture. corrosion than-the previous used iron-piping.

Control Rod Drive Circuitry Troubleshooting The control rod' drive units exhibited infrequent malfunctions-in withdrawal operation and position indication over the year.

In each case, the circuitry was either repaired or replaced immediately and operation of the circuitry was tested to; erasure it performed'in accordance'with.all previously approved changes and modifications.

D.

Procedural Changes.

Changes to the following SOP's were reviewed and approved by the Reactor Safety Board during the~ reporting period:

EFFLUENT RELEASE

SUMMARY

Introduction Summaries of radioactive effluents released from the Nuclear Science Center for 1989 are included in this Appendix.

These data are

=

presented in tabular form and includes atmospheric, liquid and solid waste releasus.

Particulate Releases 21 Radioactive particulates are monitored at the base of the central exhaust stack and summarized on a monthly basis.

The annual average release rate was 1.42 E-11 pCi/cc.

Total radioactivity released for 7

-the year was 1.06 E-03 Curies.

These data, presented in Table 1, represent output of the Nuclear Science Center Facility Air Monitoring System.

The individual particulate monitors in this system detect gross beta and gamma radiations emitted from filtered particulate

]l material.

Gascous Releases

~

Argon-41 is the major gaseous effluent produced and released at the Nuclear Science Center.

This effluent is measured by counting the Argon-41'photopeak in the gaseous discharges of the central exhaust stack.

Total Argon-41 released during 1989 was'2.46 Curies.

This results in an annual average release rate of 3 98 E-07 pC1/cc as measured in the central exhaust stack with no dilution factors applied.

Applying the dilution factor of 5.0 E-03 allowed at the site boundary (as determined, SAR, pages 116-119, June 1980) results in radioactivity concentrations of < 5.0% of the limits specified in 10CFR20, Appendix B, Table II, Column 1.

These data are summarized on a monthly basis and presented in Table 2.

_1g r.ctivity concentrations were determined for each release.

There were.

38 liquid waste releases totaling 1 33 E+09 ml (3 51 E+05) including diluents from the Nuclear Science Center during 1989 The total

=

radioactivity released for 1989 was 3 23 E-03 Ci with.an average concentration of 2.88 E-06 pCi/ml.

Summaries of the radioisotope data are presented in Tables 4 through 16.

Radioactivity concentrations for each isotope were below the limits specified in.10CFR20, Appendix B, Table II, Column 2.

K ENVIRONMENT AL SURVEY PROGRAM Introduction-The environmental survey samples were collected in accordance

=

with the schedules of the cooperative surveillance program between the Texas State Department of Health and the Texas A&M University..~These-samples were analyzed for gross gamma and beta activities and-isotope identification.

Data from these samples 1 reflect the continued use of retention facilities and-sample 1 analysis for laboratory effluents

[

prior to'their release.

.The~ environmental survey program includes the in-situ measurement of integrated radiation exposures at.the cite boundaries.

These measurements:are made for a period-of approximately 90 days-using commercially available thermoluminescent dosimeters-(TLD's)lof lithium <

fluoride chips in glass encapsulated, bulbs.

The1 dosimeters areipro-dR vided and1 processed by. Texas Department offHealth, Bureau of Radiation:

Control, Division of Environmental Programs.- The state utilizes a-i background monitor located at a point 5.25emilesLwest-southwest of the

.NSC facility.

This site for the background. measurement is generally 4

at right angles to the prevailing southeasterly winds.

j

~

Table 17. lists the average exposure rate above ambient 1 background s

for a number of' locations at-the site boundary.- The. highest-. exposure

-point was' determined to be at Site #31(390 mR/yr)fwhich isLon1the NSC I

Site Boundary fence west by south-west of-the. reactor-building.

l

.i The closest offsite point of extended occupancy is located'just

}

beyond the Site Boundary fence directly behind the Site #.10i monitoring 1

location. <From the data in Table 17, it can be easilyLshown that:

1 those occupants received much less than twice the average local offi

~

-site background exposure.

Summaries of the environmental survey program for 1989 areipre-sented'in Tables 18-21 for total (sum)l gamma or total beta activity as R

RADIATION AND CONTAMINATION CONTROL PROGRAM i y.e

~

Introduction The detection and elimination or control.of radiation hazards is an 1ntegral part of the Radiation Safety Program a. the Nuc'. ear

~

Science Center.

The radiation and smear survey programs contribute to the; control and elimination of these health hazards.

This4 program is ef fective in preventing the spread of radiaoctive contamination, j

impropdr storage of radiaoctive materials,.and unwarranted exposures

}

to radiation.

Radiation Surver The Nuclear Science Center uses an arca radiation monitoring, system consisting of ten (10) detector' channels located throughout the Reactor and Laboratory Buildings.

This-system is equipped with alarm settings and remote readouts in the control and reception rooms.

Radiation-levels and operational checks are recorded on a daily basis.

This system functions as-a radiation safety monitor for.

the early detection of radiation hazards.

-The Nuclear Science Center

-facilities and site boundaries are surveyed monthly with. beta-gamma sensitive instruments.

These measurements are takenito determine i

proper storage and identification of radioactive materials and.that visitor and routine work areas are free of radiation hazards.

Additionally, radiation monitoring support is,provided for the j

reactor operations and experimenter groups to insure the. safe handling of radioactive materials and control of personnel exposures.

At the perimeter of the NSC site, radiation levels did not exceedLthe 500 mrem dose limit during 1989 i

Contam,ination Survey

.l

-l The Nuclear Science Center is routinely surveyed for radioactive contamination every month.

This program'. includes \\the collection, analysis and evaluation of approximately 250 smear samples'and the

~ l.

decontamination,of areas and materials'with removable beta-gamma-2 radioactivities of greater than 1000 dpm/100 cm,
