EXECUTIVE SUMMARY Massachusetts Institute of Technology Massachusetts Institute of Technology Reactor Inspection Report No. 05000020/2023201 The primary focus of this routine, announced inspection was the onsite review of selected elements of the Massachusetts Institute of Technology (MIT, the licensee) research reactor safety program, including: (1) effluent and environmental monitoring, (2) review audit and design change functions, (3) emergency preparedness, (4) radiation protection, and (5) transportation activities. The U.S. Nuclear Regulatory Commission (NRC) staff determined the licensees program was in compliance with NRC requirements.

Effluent and Environmental Monitoring

Effluent monitoring satisfied license and regulatory requirements and releases were within the specified regulatory and technical specifications (TSs) limit.

Review and Audit and Design Change Functions

The MIT Reactor Safeguards Committee (RSC) met as required and reviewed the topics outlined in the TS.

  • Annual audits of facility programs were conducted as required by TS.
  • Changes to the facility were evaluated using the criteria specified in Title 10 of the Code of Federal Regulations (10 CFR) 50.59, Changes, tests and experiments.

Emergency Preparedness

The emergency preparedness program was conducted in accordance with the Emergency Plan (E-Plan), including response equipment maintenance, emergency drills, and E-Plan training.

Radiation Protection

Surveys, postings, training, and personnel dose monitoring met regulatory requirements.

  • Radiation monitoring equipment was maintained and calibrated as required by the TSs.
  • The radiation protection and the as low as reasonably achievable (ALARA) programs satisfied regulatory requirements.

Transportation Activities

The program for transportation of radioactive material (RAM) satisfied U.S. Department of Transportation (DOT) and the NRC regulations.

REPORT DETAILS Summary of Facility Status The MIT Nuclear Reactor Laboratory 6-megawatt research reactor is routinely operated in support of training, experiments, and maintenance. During this inspection, the reactor was not operated due to ongoing maintenance activities.

1.

Effluent and Environmental Monitoring a.

Inspection Scope (IP 69004)

To verify that the licensee complied with the requirements of 10 CFR Part 20, Standards for Protection against Radiation, and TS section 3.7, the inspectors examined a sample of gas and particulate radiation monitors, observed a water waste tank sample taken, observed multiple air samples taken, and reviewed selected aspects of:

facility records of measurements and analysis of effluent samples

"MIT Research Reactor Nuclear Reactor Laboratory Massachusetts Institute of Technology Annual Report to United States Nuclear Regulatory Commission for the period January 1, 2022 - December 31, 2022, dated March 30, 2023

environmental release records

secondary water tritium sample records

effluent monitoring instrumentation maintenance records b.

Observations and Findings The inspectors found that environmental radiation monitoring was accomplished by use of thermoluminescent dosimeters placed within a quarter mile of the reactor, and that doses were within regulatory limits. The inspectors also found that at least one real-time environmental monitor was at the site and one within approximately one-fourth of a mile of the site was used to verify compliance with environmental dose limits. The inspectors noted that gaseous releases from the containment exhaust stack are monitored and release amounts are calculated and documented in the annual reports; and that the airborne concentrations of the gaseous releases were within the concentrations stipulated in 10 CFR Part 20, appendix B, table 2.

The inspectors found that the combined sources of all liquid effluent releases were within the monthly average concentration limits established in 10 CFR Part 20, appendix B, table 3.

c.

Conclusion The inspectors found that effluent release measurements, liquid and gas sampling analysis, and environmental monitoring measurements, demonstrated compliance with regulatory and TS limits.
