!. Introduction j i

This progress report is repared in accor' dance with the requirements of the Nuclear Regulatory Coninission 10C FR 50.71 concerning the opreation of the University of Missouri - Rolla Nuclear Reactor Facility (license R-79).

This reactor, a swimming pool type modified BSR, war, first licensed as a 10 Kw training and research facility with inicial criticality on December 9, 1961. In January 1967 an amendment was granted by the Nuclear Regulatory Commission to upgrade the facility, allowing an increase in power level to 200 Kw.

The Nuclear Reactor Facility is operated as a university facility available to the faculty and stodents of the various departments of the university for their educational and research programs. Several other universities has made use of this facility during this report-ing period. The facility is also made available; for the purpose of training reactor personnel, to the nuclear industry and electric util-ities.

The reactor staff has continued to review the operation of the reactor facility in an effort to improve the safety and efficiency of its opera-tion and to provide conditions conductive to its utilization by students and faculty from this and other universities. The following sections ,

of this report are intended to provide a brief outline of the various aspects of. the operation of this facility including its utilization for l

education and research.

III. SUPPORTING FACILITIES j Several supporting facilities are either operated or maintained by the reactor staff for users of the reactor. These greatly contribute to the efficiency of research and ' educational programs available to the faculty and students of the University of Missouri - Rolla.

Analog Computer: This computer is currently available to faculty and students and is used in scheduled classes for both graduate and under-graduate students. Several units of auxiliary equipment are also avail-able to widen the scope of its operation.

Slow Neutron Chopper: A slow neutron chopper is available for student use at the reactor facility. This chopper, constructed as a masters research project, is mounted on the face of the thermal column door.

Neutron Diffractometer: A single crystal neutron diffractometer unit is available for use at the reactor. This unit, constructed as a masters level project, has also been used for doctoral research.

Activation Analysis Lab: The activation analysis lab has proven to be the most utilized sup')orting facility. The laboratory contains one 400 channel analyzer, and one 4096 channel analyzer, with NaI or GeLi Selectable Detector input. Included in the auxiliary equipment is a tape punch, X-Y plotter, IBM electric typewriter, multi-scaler program-mer, digital pulse stabilizer, a scope camera, and a teletype terminal.

Three scalers are included in the laboratory equipment with the appro-priate detectors for counting alpha, beta, and gamma radiation.

• A GeLi detector with background shield and a four ton low background lead shield that houses two 3X3 sodium iodide crystals is available.

These detectors are used in conjunction with the multi-channel analyzers.

Several other units of equipment are available for the detection and evaluation of radioactive materials.

Pneumatic Tube Assembly: A dual tube pheumatic system is installed in the core of the reactor. This is a dual tube system, one tube being cadmium lined, the other bare. This system is a positive pressure type, using nitrogen as the propellant.

Dynamic Void: A method of introducing a void on the perifery of the core by use of nitrogen gas. This allows for a variation in void as a function of core height, total volume or volume change.

IV. IMPROVEMENTS THe following items are considered improvements to the existing facili-ties during this reporting period.

(1) The previously purchased Solid State Area Radiation Monitoring sys-tem will replace the original Radiation Area Monitor that has been in service since 1961. The system was to be installed during the previous reporting period but manpower restriction prevented its timely instal- 1 1

lation and testing. Current plans call for installation and testing dur- '

ing the Sunrner of 1980.

(2) The purchased Magnet Power Supply and Safety Amplifier which will l replace the present system that has been in use since 1961. The new system is of solid state construction and should improve the operating reliability of the entire facility. Current plans call for installation l

and testing during the Suniner of 1980. l (3) The construction of a new office / reception and entrance to the reactor facility was completed. This has increase the useable floor  !

l space by approximately 300 sq. ft. and separates the office from the  !

controlled access area.

(4) A update to the Multi-Channel Analyzer (40% channels) was recently l purchased. This allows for faster and improved results, for various l 1

operations concerning the counting of samples for discharge, release or i

experiments. The update consists of a custom isotope library and 100 MHZ-ADC. )

1 (5) Three portable health physics ion chamber radiation detectors were  !

purchased to replace old cutie pies. These instruments serve both lab and staff for experiments or routine facility use.

V. REACTOR OPERATIONS Facility Use Table 1 depicts the corrent core loading designated as 67. The number 67 denotes the Sixty Seventh core configuration (assembly and location),

that has been used at the reactor facility sinc 6 the original operating license was issured in 1961.

Table Ib shows the only other core loaded in this reporting period. This core was a result of misplacement of a fuel assembly (F10) during a Fuel Handling Lab. This lab experiment was being conducted for measurement necessary for a sub-critical multiplication curve the fuel assembly was inadverently loaded in position C7 instead of the intended position of D8. The excess reactivity of this core (68) was measured and the assembly was relocated to its intended position. Licensed operators involved in the action were required to review the fuel handlong proce-dures. There has been at least eight fuel transfers since this problem occurred and all have been accomplished successfully.

l Core Da ta During this reporting period only core designation has been used to any extent. The "W" mode core was used for normal reactor operations since students cannot operate the reactor when the excess reactivity is above i

0.7%. The "T" mode is used for extended operation (>3 hrs), beam port  ;

or thermal column experiments. The excessp was measured cold, clean

, critical. In day to day operation the excess p is quite often lower due to temperature increase of the pool.

VI. Public Relations The reactor staff has put forth considerable effort to educate the public in the field of nuclear energy. Over 2275 persons have toured the facility during this report period. This includes groups re-presenting social, military, civic, industrial, governmental and

, educational fields. These groups are usually, given a pre-orientation lecture by members of the reactor staff. These lectures are augmented by visual aids such as slides and displays. Many high school, junior college and college groups, (from this and other universities) have at-tended the various lectures and open houses. Some groups from other universities have spent an entire day at the facility becoming acquainted with the reactor and performing simple experiments. Usually these groups are from colleges which have no reactor facilities. A guided tour by the reactor staff includes a brief description of the basic nuclear reactions, components of a nuclear reactor, a few specific examples of how nuclear energy is used in industrial and educational field and how nuclear energy helps the environmental situation.

The Nuclear Engineering faculty are members of various social civic, professional, and governmental committees. The faculty and students also are involved in speaking engagements around Missouri and several other states concerning the reactor facility and in recruiting programs at high schools and colleges.

The reactor staff is cooperating with several police departments in activation analysis of samples.

l VII. Educational Utilization l l

Approximately 47 UMR students, graduates and undergraduates have participated in classes at the facility, utilizing 2304 student - semester hours of connitted hours. Also students from several colleges, and high schools have used the facility.

l The following is a list of scheduled classes at the facility along with

)

the total hours of Rcactor Use for this reporting period. l NE 304 Reactor Lab 69.3 hrs.

NE 306 Reactor Operations 169.98 hrs.

1 NE 308 Advanced Reactor Lab 135.33 hrs. l NE 300 Special Problems 22.86 hrs.

NE 490 Research 0 hrs.

NE 1 Intro. to Nuclear Engineering 5.7 hrs.

The corrent enrollment in Nuclear Engineering is 81 students. During  !

this reporting period the reactor was used 83.3% for instruction and 16.7%

for research, i

The use of the Nuclear Reactor by departments other than Nuclear i Engineering on this campus has continued to decrease. This condition is l a common occurance with campus reactors that have been in service for a considerable number of years. This is reflected in the amount of time the reactor was used for Research during this ,(and previous) reporting periods. It should be noted however, that the reactor use has remained very high in the area of training.

The Nuclear Reactor Facility was accepted, by the Union Electric Company of St. Louis, Mo., to provide two-two week program of operational

training. This training augments the First Phase of their Commercial Nuclear Reactor Operator Training, with actual hands on experience in Start-up, Shutdown, etc. This training was provided during June and July of 1979. Another two week program was started on the last day of this reporting period (March 31,1980).

Reactor Heal th Physics Activities for the period April 1,1978 through March 31, 1979 Health Physics activities at the UMR Reactor Facility consist of radiation and contamination surveys, monitoring of personnel exposures, airborne activity, pool water activity and waste disposal. Releases of all by-

, product material to authorized, licensed recipients are surveyed and recorded. In addition, health physics activities include calibrations of portable and stationary radiation detection instruments, personnel training, special surveys and monitoring of non-routine procedures.

Routine Surveys Monthly radiatir,n surveys of the facility consist of direct gamma and neutron measurements with the reactor at full power. No unusual exposure rates were found. Monthly surface contamination surveys consist of 20-30 swipes counted separately for alpha and beta-gamma activity. In 12 monthly surveys, no significant congmination outside of contained work areas was found.

By-Product Material Release Surveys During the period, 9 shipments of by-product material were surveyed and released from the rt: actor facility. Total activity released was 41.07 mci.

All shipments were utilized on the UMR campus.

Routine Monitoring 44 Reactor Facility personnel and students frequently involved with operations in the reactor facility are currently assigned beta-gama, neutron film badges which are read twice each month. There are five beta-gamma, neutron area and spare badges assigned. 24 campus personnel and students are as-signed beta-gamma film badges and frequently TLD ring badges for materials

and X-ray work on campus. There are 20 beta-gama area and spare badges assigned. In addition, 4 direct-reading dosimeters are used for visitors and high radiation area work. There have been no personnel over exposures during the period.

Airborne activity in the reactor facility is constantly monitored by a fixed-filter, particulate air monitor (CAM) located in the reactor bay.

Rb-88 and Cs-138 are the particulate daughters of Kr-88 and Xe-138 which are monitored particulate activity above the natural background of Radon daughter products.

Argon-41, Krypton-88 and Xenon 138 are the gaseous activity routinely detected during operations.

Pool water activity is monitored monthly to insure no gross pool con-tamination nor fuel cladding rupture has occurred. Gross counts and spectra of long-lived gama activity are compared to previous monthly counts.

From April through March sample concentrations averaged 1.65X10-0 uCi/ml.

Waste Disposal Release of gaseous and particulate activity through the building exhausts is determined by relating the operating times of the exhaust fans and reactor power during fan operation to previously measured air activity at maximum reactor power. During this period 25.15 millicuries were released into the air. Released isotopes were identified as Kr-88, Rb-88, Xe-138, Cs-138 an'd Ar-41.

Soild waste, including used water filters, used resins and contaminated paper is stored and/or transferred to the campus waste storage area for later shipment to a commerical burial . site. Radioactive waste released to the sanitary sewer is primarily from regeneration of the resin exchange column.

l During this period 4 releases to the sanitary sewer totaling approximately 1200 gallons of concentrated resin regeneration solution were discharged with a total activity of 1.04 millicuries. Isotopes released were: Hydrogen-3,

Sodium-24, Cr-51, Mn-54, Fe-59, Co-58, Co-60, La-140, and Ba-140. All isotopes released were below 10 CFR 20. Appendix B, Table I, Column 2 limits.

Instrument Calibrations During this period, portable instruments were calibrated 4 times. Remote area monitors were checked for calibration 4 times. ,

IX Plans With the construction of a New office / Reception area, completed in June of 1980, the facility has a much improved appearance. This new 200 Sq. ft. area allow visitors to be screened before entrance to the Controlled Access Area (Reactor Facility). This new area is also utilized for records storage and the reactor managers office.

, The mixed core (TRIGA and MTR) fuel testing that was planned for the past year is awaiting NRC approval. The heat transfer characteristics of the mixed core is to be studied as part of a masters thesis during the summer of 1980. Wi r.h this data available it is hoped that testing can get underway at low power during the next reporting period.

An application for license renewal was submitted in November 79. The license renewal is currently being reviewed by the various NRC departments.

Their comment are being awaited before changes or revisions are made in the various documents and Standard Operating Procedures.

The facility has continued with it's involvement in reactor operator training with local electrical utilities. During this past period Two-Ten day programs were completed and another Two-Ten day program one was s tarted. Each program utilized approximately 65 hours7.523148e-4 days <br />0.0181 hours <br />1.074735e-4 weeks <br />2.47325e-5 months <br /> of instructional time per ten day program. This program is currently being reviewed by the campus administration before expansion is undertaken. The current staffing (Senior Licensed) level does not allow for more than Four-Ten day programs per year. With the addition of another Senior Reactor Operator the program could accept approximately Ten-Ten day programs while continuing all current academic programs.

1 Y Summary l

The University of Missouri - Rolla Reactor was in use approximately 72% of the time class was in session at the university or 54% of the total available time based on a 40 hr, 52 week year. The total maintance time of the facility was 624 hrs. (30%) and provided for a total availability

, (reactor operational) of 1456 hrs. (70%).

A total of 23.33 megawatt hours of energy was produced using 0.8504 grams of U 235 . The ratio of usa'ge was 83.3% for instruction and 16.7%

for research. A total of 249 samples was irradiated during this reporting period with all samples being used on a intra-campus basis.

The reactor was visited by approximately 2275 persons during the past year. At the same time there were 47 UMR students enrolled for courses at the Reactor Facility. The facility was thus comitted to over 2304 student-semester hours of classes involving about 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br /> per week during the Fall and Spring semesters.

The facility will continue to be utilized by electrical utility for i operator training. Two-Ten day programs will be completed on April 25, 1980 with two more classes scheduled for August / September 1980. There has been some contact with other utilities and training companies but due to present  !

manpower limitations we are not actively seeking new customers at this time.

The UMR Nuclear Reactor building, fire alann system consists of two type jofdetectors;fourheatsensingunitsandtwosmokedetectors,plustwo imanual alarm station.

I The system has a built in circuit failure warning system with an audible jandvisiblealarmat the control box.

i

• The alarm system is normally pewred from building power, with batteries for a backup.

When a actual alarm is initiated an internal and an external building I

fire alarm is sounded and when the building security system is in opera-tion a remote alarm is sounded at the campus police headquarters.

PROCEDURE:

1. Replace the emergency power supply batteries in the battery box.

& Test emergency power by securing power to ths alarm system (switch 32 in the power panel) and text system operational.

F Check the four heat detectors by applying a heat blower on them and acknowledging alarm actuation, audible and visible and their '

resetting af ter the heat is removed.

[ Check the two smoke detectors by placing a burning cigarette en a long pole momentarily removing all power to the alarm control box.

& Check the two manual alarm stations and acknowledge alarm dCtudtion, audibic dnd Visible and reset.

W Check all indication lights operational.
