2. Experiments a. Inspection Scope (IP 69001)

To ensure that the requirements of TS Sections 3.7 and 6.4 were being met concerning experimental programs, the inspector reviewed selected aspects and/or portions of:

Experimental administrative controls and precautions Approved reactor experiments documentation Review and approval process for experiments DNRRP No 3.3,Rules Governing Experiments, Storage and Handling of, and Accountability for Nuclear and Radioactive Material, dated December 2012 Completed TRIGA Activation Request Form forms, dated from November 2012 to present Completed Approval Sheet for Special Experiments, Annual Fuel Inspection, for 2011 and 2012 b. Observations and Findings One of the many uses for the Dow TRIGA Research Reactor (DTRR) is the irradiation of various materials. The most frequently used experimental facilities are the pneumatic tube irradiation facility and the lazy susan. Samples that have been irradiated at DTRR include various materials that are produced or utilized at Dow Chemical Company. All experiments conducted are in accordance with approved authorization requests. The Facility Director (FD) or Reactor Supervisor (RS) reviews and approves all routine samples to be irradiated in accordance with the TS limitations for each sample to be irradiated in the core.

No new routine experiments had been initiated, reviewed, or approved since the previous inspection at the facility. One special experiment was approved to conduct the annual fuel inspections with a new camera device. This special inspection must obtain ROC approval prior to performance.

-3-All new and special experiments are reviewed and approved by the ROC. The inspector confirmed that all of the experiments conducted were in accordance with TS limits and procedural requirements.

c. Conclusion No new experiments were requested. Procedures existed to review them pursuant to TS requirements should one be requested.

3. Health Physics a. Inspection Scope (IP 69001)

The inspector reviewed the following to verify compliance with 10 CFR Part 19, 10 CFR Part 20, and the applicable TS requirements:

  • radiological signs and posting in various areas of the facility
  • area and personnel dosimetry results for 2012 and 2013
  • facility and equipment during tours
  • radiation protection training records
  • maintenance and calibration of radiation monitoring equipment, including the water radioactivity monitor, area radiation monitor, and the continuous air monitor
  • organization and staffing
  • radiological signs and posting
  • DNRRP No. 3.3.3, Handling, Storage, and Disposal of Radioactive Material, dated December 2012
  • DNRRP No. 4.2.2, Area Monitor Calibration, dated November 2006
  • DNRRP No. 4.7.1, Wipe Tests and Radiation Surveys, dated November 2006 b. Observations and Findings (1) Surveys The inspector reviewed monthly radiation and contamination surveys of the reactor building, which were conducted by the facility staff. The results were documented on the appropriate forms, evaluated as required and corrective actions taken when readings or results exceeded set action levels. The number and location of survey points was adequate to characterize the radiological conditions. The licensee investigates any readings above background levels. The inspector verified that the Radiation Safety Officer (RSO) reviews all of the survey records. One elevated reading was discovered this year during the annual audit wipe test and decontaminated as necessary. The inspector verified that the licensee implemented corrective action to reduce the levels of contamination.

-4-The RSO also conducts an annual independent contamination survey of the facility and has verified that all of the readings are as expected.

(2) Postings and Notices The inspector reviewed the postings required by 10 CFR Part 19 at the entrances to various controlled areas including the Reactor Bay, and radioactive material storage areas. The postings were acceptable and indicated the radiation and contamination hazards present. The facilitys radioactive material storage areas were found to be properly posted. No unmarked radioactive material was found in the facility.

(3) Dosimetry The licensee used a National Voluntary Laboratory Accreditation Program-accredited vendor to process personnel dosimetry. Through direct observation, the inspector determined that dosimetry was used in an acceptable manner by facility personnel. For visitors to the facility, radiation exposures are recorded through the permanent staff at the facility. Records indicate that no abnormal readings were obtained.

An examination of the records for the inspection period showed that all exposures were well within NRC limits and within licensee action levels.

All of the staff and researchers associated with the facility wear Optically Stimulated Luminescense Dosimeter (OSLD) badges and minimal doses were recorded for 2012 through present. The as low as reasonably achievable (ALARA) goal specified in the radiation safety procedures is to keep exposures to less than 10% of the applicable NRC requirements and the licensee consistently meets this goal.

(4) Radiation Monitoring Equipment The calibration verification of portable survey meters and friskers was completed by a contracted company. The calibration records of portable survey meters, friskers, fixed radiation detectors, and air monitoring equipment in use at the facility were reviewed. Calibration frequency met the requirements established in TS 4.4 while records were being maintained as required. The inspector verified that proper precautions are always used to maintain doses ALARA while conducting the calibrations. The inspector reviewed the licensees tracking system for ensuring the instrument calibrations are completed on time and found it to be useful.

(5) Radiation Protection Program The licensees Radiation Protection Program (RPP) was established through the procedures. The RPP provides guidance for keeping doses ALARA and is consistent with the guidance in 10 CFR Part 20. The inspector verified that the RPP was being reviewed annually as required

-5-by 10 CFR 20.1101(c). No issues related to the RPP were identified in the review of the program. The RSO reviews the overall implementation of the radiation protection program at the DTRR.

The RPP requires that all personnel who work with radioactive materials receive training in radiation protection, policies, procedures, requirements, and the facilities prior to having unescorted access at the facility. The RSO is responsible for conducting the training and all of the training is typically conducted both on a computer and with practical applications. A test is administered at the end of the training to verify that the individuals understood the material presented. The training covered the topics required to be taught in 10 CFR Part 19 and the review of training materials and tests indicated that the staff were instructed on the appropriate subjects.

(6) Facility Tour The inspector toured the reactor facility, counting laboratories and accompanying facilities. Control of radioactive material and control of access to radiation and high radiation areas were observed to be acceptable. The postings and signs for these areas were appropriate.

Licensee personnel followed the indicated precautions for access to controlled areas.

(7) Environmental Monitoring Several OSLDs were placed around the inside walls of the reactor facility and minimal doses were recorded. Records show that there was minimal radiation exposure to the environment from the reactor during the previous year. There was no liquid effluent discharged from the reactor facility. The licensee indicated that gaseous effluents from the reactor facility were less than 1 mrem/year.

c. Conclusion The inspector determined that: (1) surveys were being completed and documented as required, (2) postings met regulatory requirements, (3) personnel dosimetry was being worn and recorded doses were within the NRCs regulatory limits, (4) radiation monitoring equipment was being maintained and calibrated as required, (5) the RPP satisfied regulatory requirements, 6) the radiation protection training program was being administered as required, and 7)

environmental monitoring satisfied license and regulatory requirements.

Observations and Findings The inspector reviewed the revised E-Plan in use at the DTRR and verified that the E-Plan was being properly implemented at the facility. The inspector reviewed the emergency facilities, instrumentation, and equipment and verified that the emergency response equipment, in general, was as described in the E-Plan.

-7-Through direct observation, records review, and interviews with emergency organization personnel, the inspector determined that they were capable to respond, and knowledgeable of the proper actions to take in case of an emergency. The facility staff is responsible for responding to an emergency during all hours and making assessments and corrective as well as protective actions. The responsibility and authority for directing and coordinating emergency response activities are assigned to the FD/RS, acting as the emergency director. All facility personnel receive annual emergency response training. The inspector verified that the licensee has continually reviewed the E-Plan and conducted an inventory of the emergency response equipment.

Emergency drills had been conducted annually as required by the E-Plan. The drill for 2013 was both practical exercises and tested the notification and response of emergency personnel. Critiques were written and discussed following the drills to document any problems identified during the exercises.

The action items that resulted were incorporated as part of the lesson learned policy.

The inspector visited the 1100 building, which is the Dow Emergency Services and Security Center. While at the center, the inspector talked to the Emergency Services and Security Delivery Specialist about the supplies and equipment at the Support Center that would be available in case of an emergency. The coordinator stated that designated individuals on the emergency services teams had radiation training and if additional support is needed, other support staff can respond. The staff was very helpful and knowledgeable on the requirements and their responsibilities. The inspector observed that there appeared to be a good working relationship between the licensee and the Emergency Services and Security Center which was capable to handle a variety of events that could happen at the DTRR.

c. Conclusion The emergency preparedness program was conducted in accordance with the requirements stipulated in the E-Plan.
