UNIVERSITY OF MISSOURI - COLUMBIA RESEARCH REACTOR REACTOR OPERATIONS ANNUAL REPORT January 1,2013 through December 31, 2013 INTRODUCTION The University of Missouri Research Reactor (MURR) is a multi-disciplinary research and education facility providing a broad range of analytical, materials science and irradiation services to the research community and the commercial sector.
Scientific programs include research in archaeometry, epidemiology, health physics, human and animal nutrition, nuclear medicine, radiation effects, radioisotope studies, radiotherapy, boron neutron capture therapy and nuclear engineering; and research techniques including neutron activation analysis, neutron and gamma-ray scattering and neutron interferometry. The heart of this facility is a pressurized, reflected, open pool-type, light water moderated and cooled, heterogeneous reactor designed for operation at a maximum steady-state power level of 10 Megawatts thermal - the highest powered university-operated research reactor in the United States.
The Reactor Operations Annual Report presents a summary of reactor operating experience for calendar year 2013.
Included within this report are changes to MURR reactor operations and health physics procedures, revisions to the Hazards Summary Report, facility modifications, new tests and experiments, reactor physics activities and environmental and health physics data.
This report is being submitted to the U.S. Nuclear Regulatory Commission (NRC) to meet the administrative requirements of MURR Technical Specification 6.1.h (4).
ACKNOWLEDGMENTS The success of MURR and these scientific programs is due to the dedication and hard work of many individuals and organizations. Included within this group are: the University administration; the governing officials of the State of Missouri; the Missouri State Highway Patrol; the City of Columbia Police Department; the Missou'i University Police Department (MUPD); the Federal Bureau of Investigation (FBI); our regulators; those who have provided funding including the Department of Energy (DOE), the National Nuclear Security Administration (NNSA) and the Department of Homeland Security (DHS);
Argonne National Laboratory (ANL); Idaho National Laboratory (INL); Sandia National Laboratories (SNL); the researchers; the students; the Columbia Fire Department; the Campus Facilities organization; members of the National Organization of Test, Research and Training Reactors (TRTR); and many others who have made, and will continue to make, key contributions to our overall success. To these individuals and organizations, the staff of MURR wishes to extend its fondest appreciation.
Some of the major facility projects that were supported by Reactor Operations during this calendar year included (1) implementing Amendment No. 36 to Amended Facility License No. R-103, which revised the Safety Limit Curves based on newer, more accurate power peaking factors developed using a 3-dimensional diffusion code, (2) replacement of the 30-degree graphite reflector elements 'GH' and IJ' with a single 60-degree graphite reflector element 'GHIJ,' and (3) irradiating and processing a 5-gram natural uranium target to determine the feasibility of producing molybdenum-99 using a selective gaseous extraction process.
Additionally, in August 2006 MURR submitted a request to the NRC to renew i
Amended Facility License No. R-103. Significant efforts have already been placed in responding to the Requests for Additional Information and these efforts continued in this past year.
The facility continues to actively collaborate with the Reduced Enrichment for Research and Test Reactors (RERTR) Program and four other U.S. high-performance research reactor facilities that use highly-enriched uranium (HEU) fuel to find a suitable low-enriched uranium (LEU) fuel replacement. Although each one of the five high-performance research reactors is responsible for its own feasibility and safety studies, regulatory interactions, fuel procurement and conversion, there are common interests and activities among all five reactors that will benefit from a coordinated, working-group effort. This past year, resources were focused on completing Phase 1 accident analyses for the LEU conversion core.
MURR also hosted the 2013 Annual Test, Research and Training Reactors Conference.
The TRTR organization represents research reactor facilities across the nation from government, major universities, national laboratories and industry.
TRTR's primary mission is education, fundamental and applied research, application of technology in areas of national concern and improving U.S. technological competitiveness around the world.
TRTR membership includes managers and directors of research reactors, educators, administrators, regulators and research scientists and engineers.
Reactor Operations Management also wishes to commend the five individuals who received their Reactor Operator certifications and the four individuals who received their Senior Reactor Operator certifications from the NRC. These individuals participated in a rigorous training program of classroom seminars, self-study and on-the-job training. The results of this training are confident, well-versed, decisive individuals capable of performing the duties of a licensed operator during normal and abnormal situations.

of full power operation per week. Total time is the January 2013 The reactor operated continuously in January with the following exceptions: four shutdowns for scheduled maintenance and/or refueling and one shutdown for physics measurements. There were no unscheduled/unplanned power reductions this month.
Major maintenance items for the month included:
replacing Reactor Pool Reflector Region Differential Pressure Transmitter PT-917; and performing a reactivity worth measurement in accordance with reactor procedure RP-RO-201, "Measurement of Reactivity Worth of Flux Trap Loadings or Individual Samples, RTP-17(B).'"
February 2013 The reactor operated continuously in February with the following exceptions:
four shutdowns for scheduled maintenance and/or refueling, two shutdowns for physics measurements and two unscheduled/unplanned power reductions.
On February 23, with the reactor operating at 10 MW in the automatic control mode, a "Rod Not In Contact With Magnet" rod run-in was automatically initiated when the reactor safety system yellow leg Trip Actuator Amplifier 1-1
(TAA) de-energized, causing control blades 'A' and 'B' anvils to separate from their electromagnets and drop. A manual scram was then initiated and all immediate and subsequent actions of reactor emergency procedure REP-2, "Reactor Scram," were performed. Investigation of all relays and wiring associated with this portion of the reactor safety system revealed that a normally closed contact in the manual scram switch., 1SI 0, was intermittently making a poor connection.
The contact blocks in the manual scram switch were burnished and the yellow leg TAA was replaced. The system was retested satisfactorily and permission to restart the reactor was obtained from the Reactor Manager. The reactor was refueled and subsequently restarted to 10 MW operation.
On February 23, with the reactor operating at 10 MW in the automatic control mode, a reactor scram was automatically initiated when an interruption in electrical supply power from the University Power Plant to the facility occurred. All immediate and subsequent actions of reactor emergency procedure REP-11, "Momentary Loss of Normal Electrical Power," were performed.
Permission to restart the reactor was obtained from the Lead Senior Reactor Operator after confirmation from the power plant that the cause of the interruption in electrical power was corrected. A "hot reactor startup" was performed to return the reactor to 10 MW operation.
Major maintenance items for the month included: replacing the 30-degree graphite reflector elements 'GH' and 'IJ' with a single 60-degree graphite reflector element 'GHIJ;' and replacing the pool coolant demineralizer system inlet filters.
March 2013 The reactor operated continuously in March with the following exceptions:
four shutdowns for scheduled maintenance and/or refueling, two shutdowns for physics measurements and four unscheduled/unplanned power reductions. U.S. Nuclear Regulatory Commission inspector arrived at the facility for a routine inspection of the Radiation Protection Program and Shipping.
On March 4, while reviewing a list of the completed maintenance items and compliance procedures performed that day, the Surveillance Programs System Specialist discovered that compliance procedure CP-27, "Power Level Interlock Static Scram," was not completed within the prescribed Technical Specification (TS) periodicity. Failure to perform the surveillance within the required time interval resulted in a deviation from TS 5.4. Licensee Event Report No. 13-01 was submitted to the U.S. Nuclear Regulatory Commission on April 2, 2013. The compliance procedure was performed on March 11, the next scheduled maintenance day after discovery of the error.
On March 5, with the reactor operating at 10 MW in the automatic control mode, an unannounced (no audible or visual alarm occurred) rod run-in was automatically initiated. The control room operator immediately noted all four shim control blades moving in the inward direction. After a brief investigation was unable to determine the cause of the rod run-in, the rod run-in was not manually reset and the reactor was shut down. Subsequent investigation of all power supplies, relays, switches and wiring connections associated with the rod run-in system revealed no abnormalities.
Additional troubleshooting and investigation were unable to reproduce this system response.
Operational checks of the rod run-in system were performed satisfactorily. The reactor was refueled and permission to restart the reactor was obtained from the Reactor Manager. The reactor was subsequently restarted to 10 MW operation.
On March 5 (5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> and 55 minutes after the previous power reduction), with the reactor operating at 10 MW in the automatic control mode, an unannounced (no audible or visual alarm occurred) rod run-in was automatically initiated.
The control room operator immediately noted all four shim control blades moving in the inward direction. After a brief investigation was unable to determine the cause of the rod run-in, the reactor was manually scrammed. The immediate actions of reactor emergency procedure REP-2, "Reactor Scram," were performed.
Subsequent 1-2
investigation did not identify a failed component; however, the most likely cause was a failure of either the rod run-in system Trip Actuator Amplifier (TAA) or Non-Coincidence Logic Unit (NCLU). The rod run-in system TAA and NCLUs were replaced and operational checks of the rod run-in system were performed satisfactorily. Permission to restart the reactor was obtained from the Reactor Manager. The reactor was subsequently restarted to 10 MW operation.
On March 13, with the reactor operating at 10 MW in the automatic control mode, a "Rod Not in Contact with Magnet" rod run-in was automatically initiated when control blade 'D' anvil separated from its electromagnet during a routine sample handling evolution.
The immediate actions of reactor emergency procedure REP-2, "Reactor Scram," were performed. The operators involved were counseled on the importance of proper sample handling techniques near the offset mechanisms. Visual verification of the pull rod to housing alignment was performed. The reactor was refueled and permission to restart the reactor was obtained from the Lead Senior Reactor Operator. The reactor was subsequently restarted to 10 MW operation.
On March 20, with the reactor operating at 10 MW in the automatic control mode, a "Rod Not in Contact with Magnet" rod run-in was automatically initiated when control blade 'A' anvil separated from its electromagnet during a routine sample handling evolution.
The immediate actions of reactor emergency procedure REP-2, "Reactor Scram," were performed. The operators involved were counseled on the importance of proper sample handling techniques near the offset mechanisms. Visual verification of the pull rod to housing alignment was performed. The reactor was refueled and permission to restart the reactor was obtained from the Lead Senior Reactor Operator. The reactor was subsequently restarted to 10 MW operation.
Major maintenance items for the month included: completing Modification Record 13-03, "Replacement of GH and IJ Wedge with a Single 600 Wedge;" completing Modification Record 12-02, "Control Blade Fabrication Alternative Using Laser Welding;" completing Modification Record 01-02, Addendum 9, "Intercommunication and Paging System Changes in Support of MURR Industrial Building (Room 299) Renovations;" performing two reactivity worth measurements in accordance with reactor procedure RP-RO-201, "Measurement of Reactivity Worth of Flux Trap Loadings or Individual Samples, RTP-17(B);" performing a reactivity worth measurement in accordance with reactor procedure RP-RO-203, "Measurement of the Primary Coolant/Moderator Temperature Coefficient of Reactivity, RTP-19," in support of a Nuclear Engineering Department practicum; performing a reactivity worth measurement in accordance with reactor procedure RP-RO-200, "Measurement of Differential Worth of a Shim Blade, RTP-II(D)," in support of a Nuclear Engineering Department practicum; and loading new de-ionization bed
'F' and placing on pool coolant system service.
April 2013 The reactor operated continuously in April with the following exceptions: five shutdowns for scheduled maintenance and/or refueling, one shutdown for physics measurements and one unscheduled/unplanned power reduction. One additional reactor startup and shutdown were performed in support of NRC operator license examinations. MURR received notification from the U.S. Nuclear Regulatory Commission that two new Reactor Operator and one new Senior Reactor Operator licenses had been issued.
On April 30, with the reactor operating at 10 MW in the automatic control mode, an unannounced (no audible or visual alarm occurred) rod run-in was automatically initiated. The control room operator immediately noted all four shim control blades moving in the inward direction.
The reactor was then subsequently shut down. Subsequent investigation did not identify a failed component; however, two resistors in the Trip Actuating Amplifier (TAA) circuit were determined to have resistance values outside their specified tolerances. Both resistors were replaced.
1-3
Operational checks of the rod run-in system were performed satisfactorily and permission to restart the reactor was obtained from the Reactor Manager. The reactor was subsequently restarted to 10 MW operation.
Major maintenance items for the month included: performing extensive troubleshooting on the rod run-in system wiring; completing Modification Record 11-03, Addendum 1, "Addition of Blow-Down Meter to the Data Acquisition Monitoring System;" completing Modification Record 13-02, "Replacement of Secondary Chemistry Controllers;" replacing primary coolant circulation pump P-501A; performing a reactivity worth measurement in accordance with reactor procedure RP-RO-201, "Measurement of Reactivity Worth of Flux Trap Loadings or Individual Samples, RTP-I 7(B);" performing a reactivity worth measurement in accordance with reactor procedure RP-RO-200, "Measurement of Differential Worth of a Shim Blade, RTP-I I(D);" replacing the actuator for manual scram switch, I SI0; and completing the biennial change-out of Control Blade 'A' Offset Mechanism and associated retesting.
May 2013 The reactor operated continuously in May with the following exceptions: five shutdowns for scheduled maintenance and/or refueling, one shutdown for physics measurements and three unscheduled/unplanned power reductions.
On May 7, with the reactor operating at 10 MW in the automatic control mode, a manual scram was initiated when an operator discovered the regulating blade would not move in the inward direction. The immediate actions of reactor emergency procedure REP-2, "Reactor Scram" were performed. Subsequent investigation revealed the ball plunger for the overload clutch had loosened and slightly backed out preventing the movement of the servomotor from being transferred to the lead screw assembly, thus preventing the regulating blade from being able to drive in the outward and inward directions. The overload clutch was inspected and the ball plunger was replaced. Operational checks of the regulating blade were performed satisfactorily and permission to restart the reactor was obtained from the Reactor Manager. The reactor was subsequently restarted to 10 MW operation.
Failure of the regulating blade to be operable during reactor operation resulted in a deviation from Technical Specification 3.4.c. Licensee Event Report No. 13-02 was submitted to the U.S. Nuclear Regulatory Commission on June 4, 2013.
On May 8, with the reactor operating at 10 MW in the automatic control mode, a "Rod Not in Contact with Magnet" rod run-in was automatically initiated when control blade 'D' anvil separated from its electromagnet during a routine sample handling evolution. The immediate actions of reactor emergency procedure REP-2, "Reactor Scram," were performed. The operators involved were counseled on the importance of proper sample handling techniques near the offset mechanisms. Visual verification of the pull rod to housing alignment was performed. The reactor was refueled and permission to restart the reactor was obtained from the Lead Senior Reactor Operator.
The reactor was subsequently restarted to 10 MW operation.
On May 14, with the reactor operating at 10 MW in the automatic control mode, an unannounced (no audible or visual alarm occurred) reactor scram was automatically initiated. Investigation revealed all monitored parameters were normal and none had trended toward an automatic scram set point or exhibited any abnormalities. Subsequent troubleshooting efforts led to the replacement of Power Level Interlock relay I1K26. Operational checks of the Power Level Interlock circuit were performed satisfactorily and permission to restart the reactor was obtained from the Reactor Manager. The reactor was subsequently restarted to 10 MW operation.
Major maintenance items for the month included:
replacing Power Level Interlock relay IK26; replacing the diaphragm and inlet and outlet flange gaskets for pool coolant demineralizer pump P-513B Discharge Valve 515N; 1-4
completing compliance procedure CP-26, "Containment Building Compliance Test;" and performing a reactivity worth measurement in accordance with reactor procedure RP-RO-201, "Measurement of Reactivity Worth of Flux Trap Loadings or Individual Samples, RTP-17(B)."
June 2013 The reactor operated continuously in June with the following exceptions: four shutdowns for scheduled maintenance and/or refueling, one shutdown for physics measurements and two unscheduled/unplanned power reductions.
On June 11, with the reactor operating at 10 MW in the automatic control mode, a "Rod Not in Contact with Magnet" rod run-in was automatically initiated when control blade 'A' anvil separated from its electromagnet during a routine sample handling evolution. The reactor was manually scrammed and the immediate actions of reactor emergency procedure REP-2, "Reactor Scram," were performed.
Inspection of the offset mechanism pull rod and housing revealed a slight misalignment between the anvil and electromagnet. The lower drive limit switch was adjusted and the anvil and electromagnet were cleaned. The control rod was satisfactorily withdrawn to the full out position as part of the retest by performing compliance procedure CP-10, "Rod Drop Times." Permission to perform a "hot reactor startup" was obtained from the Reactor Manager. While conducting the "hot reactor startup," the Reactor Operator noted, immediately after stabilizing reactor power level at 5 MW, that the heights of shim control blades 'B' and 'D' were at 21.90 and 23.10 inches, respectively. This 1.20 inch difference in shim blade height created a deviation from Technical Specification (TS) 3.2.b, which states, "Above 100 kilowatts the reactor shall be operated so that the maximum distance between the highest and lowest shim blade shall not exceed one inch." Licensee Event Report No. 13-03 was submitted to the U.S. Nuclear Regulatory Commission on July 10, 2013.
On June 14, with the reactor operating at 10 MW in the automatic control mode, an unannounced (no audible or visual alarm occurred) rod run-in was automatically initiated. The control room operator immediately noted all four shim control blades moving in the inward direction. The reactor was then subsequently shut down. Subsequent investigation did not identify a failed component.
Additional troubleshooting and investigation were unable to reproduce this system response. Operational checks of the rod run-in system were performed satisfactorily.
The reactor was refueled and permission to restart the reactor was obtained from the Reactor Manager. The reactor was subsequently restarted to 10 MW operation.
Major maintenance items for the month included: performing extensive troubleshooting on the rod run-in system wiring connections; completing Modification Record 13-04, "Rod Run-In Monitoring System;" completing Modification Record 75-01, Addendum 3, "Rod Run-In Electronic Circuit Jumper Panel;" completing Modification Record 13-01, "Replacement of TE-980A and TE-980B Power Supply 2PS5;" performing a reactivity worth measurement in accordance with reactor procedure RP-RO-201, "Measurement of Reactivity Worth of Flux Trap Loadings or Individual Samples, RTP-17(B);" and replacing the Loss of Voltage to Magnet A and B Scram relay 2K20 and the Loss of Voltage to Magnet C and D Scram relay 2K2 1.
July 2013 The reactor operated continuously in July with the following exceptions: five shutdowns for scheduled maintenance and/or refueling and two unscheduled/unplanned power reductions. U.S. Nuclear Regulatory Commission inspector arrived at the facility for a routine inspection of Security and Material Control and Accountability. The U.S. Nuclear Regulatory Commission issued Amendment No. 36 to Amended Facility License No. R-103.
On July 3, with the reactor operating at 10 MW in the automatic control mode, a "Power Level Interlock or FIRST" scram was automatically initiated when the FIRST Support Rig was inadvertently bumped while performing a routine 1-5
sample handling evolution. The immediate actions of reactor emergency procedure REP-2, "Reactor Scram," were performed. The flux trap sample holder was verified to be positively latched to the inner reactor pressure vessel. The operators involved were counseled on the importance of proper handling techniques near the FIRST Support Rig.
The reactor was refueled and permission to restart the reactor was obtained from the Reactor Manager. The reactor was subsequently restarted to 10 MW operation.
On July 15, during a reactor startup with the reactor subcritical, a "Rod Not in Contact with Magnet" rod run-in was automatically initiated when control blade 'B' anvil separated from its electromagnet during a shimming evolution.
The reactor was shut down and the immediate actions of reactor emergency procedure REP-2, "Reactor Scram," were performed. The mating surfaces between the control rod drive mechanism electromagnet and pull rod anvil were cleaned and proper alignment of the offset mechanism pull rod and housing were verified. The control rod was satisfactorily withdrawn to the full out position as part of the retest by performing compliance procedure CP-10, "Rod Drop Times." Permission to restart the reactor was obtained from the Reactor Manager.
Major maintenance items for the month included: performing a reactivity worth measurement in accordance with reactor procedure RP-RO-200., "Measurement of Differential Worth of a Shim Blade, RTP-I I(D);" performing a reactivity worth measurement in accordance with reactor procedure RP-RO-201, "Measurement of Reactivity Worth of Flux Trap Loadings or Individual Samples, RTP-17(B);" replacing Vent Tank Discharge Check Valve 550A; replacing Pool Below Refuel Level relay 2K5; replacing the chassis edge connectors for the rod run-in system and the reactor safety system Trip Actuator Amplifiers and Non-Coincidence Logic Units; and replacing the air actuator and diaphragm on pressurizer Water Drain Valve 527A.
August 2013 The reactor operated continuously in August with the following exceptions:
four shutdowns for scheduled maintenance and/or refueling, one shutdown for physics measurements, one shutdown for training and four unscheduled/unplanned power reductions.
On August 21, with the reactor operating at 10 MW in the automatic control mode, a "Reactor Loop Low Pressure" scram was automatically initiated. All immediate and subsequent actions of reactor emergency procedure REP-3, "Primary Coolant System Low Pressure or Flow Scram," were performed.
No actual low pressure condition indication was present. Investigation determined the most likely cause to be reactor core outlet pressure channels 944A or 944B. Contacts on Reactor Pressure/Flow Interlock relays 2K32 and 2K33 were burnished, reactor core outlet pressure transmitters were vented and applicable sections of compliance procedure CP-22, "Pressure Transmitters PT-944A/B and PT-943," were completed satisfactorily. The reactor was refueled and permission to restart the reactor was obtained from the Reactor Manager.
The reactor was subsequently restarted to 10 MW operation.
On August 23, with the reactor operating at 10 MW in the automatic control mode, a "Reactor Loop Low Pressure" scram was automatically initiated. All immediate and subsequent actions of reactor emergency procedure REP-3, "Primary Coolant System Low Pressure or Flow Scram," were performed.
No actual low pressure condition indication was present. Investigation determined the cause to be an intermittent failure of reactor core outlet pressure 944B meter/relay unit. The meter/relay unit was replaced and applicable sections of compliance procedure CP-22 "Pressure Transmitters PT-944A/B and PT-943," were completed satisfactorily.
The reactor was refueled and permission to restart the reactor was obtained from the Reactor Manager. The reactor was subsequently restarted to 10 MW operation.
1-6
On August 25, with the reactor operating at 10 MW in the automatic control mode, a "Rod Not in Contact with Magnet" rod run-in was automatically initiated when control blade 'D' anvil was separated from its electromagnet during a routine sample handling evolution. The immediate actions of reactor emergency procedure REP-2, "Reactor Scram," were performed. The operators involved were counseled on the importance of proper sample handling techniques near the offset mechanisms. Visual verification of the pull rod to housing alignment was performed. The reactor was refueled and permission to restart the reactor was obtained from the Reactor Manager. The reactor was subsequently restarted to 10 MW operation.
On August 26, during a reactor startup with the control blades at approximately 11 inches withdrawn (subcritical), a "Channel 2 & 3 Period" scram was automatically initiated when Nuclear Instrumentation (NI) Intermediate Range Channel No. 2 period indication increased above the scram set point. The duty operator noted all power level and period indications other than those from NI Signal Processor No. 1 were normal. All immediate actions of reactor emergency procedure REP-2, "Reactor Scram," were performed. Troubleshooting efforts led to the replacement of NI Signal Processor No. I fission chamber and its associated cabling. An instrument channel calibration and pre-operational checks were performed satisfactorily, including a response check using the neutron source. The reactor was refueled and permission to restart the reactor was obtained from the Reactor Manager.
The reactor was subsequently restarted to 10 MW operation.
Major maintenance items for the month included: completing Modification Record 04-05, Addendum 8, "Cooling Tower Electrical Arc Flash Danger Mitigation;" completing Modification Record 12-01, "Replace PT-944A/B with Rosemount Transmitters;" performing a reactivity worth measurement in accordance with reactor procedure RP-RO-201, "Measurement of Reactivity Worth of Flux Trap Loadings or Individual Samples, RTP-17(B);" performing a chemical cleaning of the secondary coolant side of primary coolant heat exchanger HX-503A; loading new de-ionization bed 'D' and placing it on pool coolant system service; and replacing the fission chamber detector and associated cabling for NI Signal Processor No. 1.
September 2013 The reactor operated continuously in September with the following exceptions:
four shutdowns for scheduled maintenance and/or refueling, one shutdown for physics measurements, two shutdowns for training and two unscheduled/unplanned shutdowns.
On September 16, with the reactor operating at 10 MW in the automatic control mode, a reactor shutdown was initiated after the duty operator observed a blown fuse indication on Annunciator Control Power Fuse 2F7, accompanied, shortly thereafter, by an Uninterruptible Power Supply (UPS) trouble alarm. All other indications for 10 MW operation were normal. Further investigation revealed that the Annunciator 115VAC Supply Breaker on UPS Panel No. 2 was in the tripped condition and the Annunciator inoperable. Troubleshooting efforts determined that the most likely cause of the blown fuse and tripped breaker was a faulty alarm module. The Annunciator alarm module for "Channel 4, 5, or 6 Downscale" function was replaced and an operational test of the Annunciator was completed satisfactorily. Permission to the restart the reactor was obtained from the Reactor Manager. The reactor was subsequently returned to 10 MW operation.
On September 23, with the reactor operating at 10 MW in the automatic control mode, a reactor shutdown was initiated after the duty operator observed a greater than normal lowering of pressurizer liquid level of approximately 2 inches per hour. This abnormal decrease in liquid level was observed shortly after a reactor startup. A reactor refueling had been performed earlier in the day. Subsequent investigation revealed that the source of leakage was from the pressure vessel head packing gland seal, which provides the seal between the pressure vessel head and inner reactor pressure vessel. Note: The pressure vessel head is removed and then subsequently replaced and tightened 1-7
after refueling a core has been completed. The packing gland was tightened and permission to restart the reactor was obtained from the Reactor Manager. The reactor was returned to 10 MW operation. Operators were subsequently counseled on proper bolting techniques.
Major maintenance items for the month included:
completing Modification Record 01-02, Addendum 10, "Intercommunication and Paging System Changes in Support of MURR Industrial Building (Room 299), Room 243, Room 246 and Room 271 Renovations;" performing a reactivity worth measurement in accordance with reactor procedure RP-RO-201, "Measurement of Reactivity Worth of Flux Trap Loadings or Individual Samples, RTP-17(B);" completing a change-out of Control Blade 'A' Offset Mechanism and associated retesting; and replacing the "Channel 4, 5 or 6 Downscale" annunciator alarm module.

November 2013 The reactor operated continuously in November with the following exceptions:
four shutdowns for scheduled maintenance and/or refueling, two shutdowns for physics measurements and one unscheduled/unplanned power reduction. Three additional reactor startups and shutdowns were performed in support of NRC operator license examinations. U.S. Nuclear Regulatory Commission inspector arrived at the facility for a routine inspection of Reactor Operations and Emergency Preparedness. MURR received notification from the U.S. Nuclear Regulatory Commission that three new Reactor Operator and three new Senior Reactor Operator licenses had been issued.
On November 11, with the reactor operating at 10 MW in the automatic control mode, a "Rod Not in Contact with Magnet" rod run-in was automatically initiated when control blade 'D' anvil separated from its electromagnet during a routine sample handling evolution.
The immediate actions of reactor emergency procedure REP-2, "Reactor Scram," were performed. The operators involved were counseled on the importance of proper sample handling techniques near the offset mechanisms. Visual verification of the pull rod to housing alignment and operability tests were performed satisfactorily. The reactor was refueled and permission to restart the reactor was obtained from the Lead Senior Reactor Operator. The reactor was subsequently restarted to 10 MW operation.
Major maintenance items for the month included: performing a reactivity worth measurement in accordance with reactor procedure RP-RO-200, "Measurement of Differential Worth of a Shim Blade, RTP-I1(D);" and performing pre-beryllium change-out center test hole flux profile measurements.

SECTION VIII ENVIRONMENTAL MONITORING AND HEALTH PHYSICS SURVEYS January 1, 2013 through December 31, 2013 Environmental samples are collected two times per year at eight (8) locations and analyzed for radioactivity. Soil and vegetation samples are also taken at each location. Water samples are taken at three (3) of the eight (8) locations. Subsurface soil monitoring commenced in 2013 with six (6) samples taken each period. Analytical results are shown in Tables 1 and 2.
Table 3 lists the radiation doses recorded by the environmental monitors deployed around MURR in 2013. All doses are approximately 20 mRem/year or less, except monitor numbers 9 and 15. These monitors are located near loading dock areas where packages containing radioactive material are loaded on transport vehicles. The doses recorded by these monitors are considered to be the result of exposure to packages in transit. Additionally, during 2013, six (6) monitoring sites around the reactor facility were chosen for subsurface soil monitoring. The subsurface results are presented along with the traditional monitoring locations and results. The environmental monitoring program confirms that minimal environmental impact exists from the operation of the MURR facility.
The number of radiation and contamination surveys performed each month is provided in Table 4.
