APPENDIX A TECHNICAL SPECIFICATIONS FOR THE LICENSE NO. TR-3, Amendment 13 AND LICENSE NO. R-93, Amendment 9 NATIONAL AERONAUTICS AND SPACE ADMINISTRATION PLUM BROOK STATION SANDUSKY, OHIO DOCKET NOS. 50-30 AND 50-185

TECHNICAL SPECIFICATIONS

1.0 INTRODUCTION

These Technical Specifications apply to all activities conducted at the Plum Brook Reactor Facility (PBRF) under the provisions of NRC License TR-3 for the Plum Brook Research Reactor, and License R-93 for the Plum Brook Mock-up Reactor. Both reactors were shut down in 1973. They were de-fueled and all new and irradiated fuel was removed from the site. Both of these reactors and their associated systems are located in the same controlled area at the PBRF on Plum Brook Station, and both are undergoing decommissioning.

1.1 DEFINITIONS 1.1.1 Authorized Entry: Entry to the PBRF which is sanctioned by the PBRF physical security plan (section 6 of the Decommissioning Plan), for those persons having a legitimate need to enter and who have knowledge of the conditions, hazards, and procedures at the facility, or who are accompanied by an authorized person with this knowledge.

1.1.2 Containment

A closure on a volume within the facility, which prevents the uncontrolled spread of contamination and controls the movement of air (inward and outward) through a controlled path.

1.1.3 Containment Device: A Containment Device is an engineered barrier that does not necessarily constitute total enclosure, and is used to prevent the spread of radioactive contamination and airborne radioactivity.

1.1.4 Containment Vessel: The Containment Vessel is the structure that provides containment for the main reactor plant components.

1.1.5 Decommissioning Activities: Decommissioning activities means all administrative and industrial efforts employed in order to achieve decommissioning. Some examples of such activities include decontamination, demolition, deconstruction, radiological surveys, and the shipping and receiving of radioactive materials, apparatus and equipment.

1.1.6 Operable

Operable means that a system, structure, or component is capable of performing its intended function in the intended manner.

1.1.7 Operating

Operating means that a structure, system, or component is performing its intended function in the intended manner.

1.1.8 Source Term: The magnitude and mix of radionuclides present in PBRF systems, structures and components, which are the result of PBRF reactor operations. The major portions of the source term are comprised of the Reactor Tank and internals, associated reactor piping and system components, and activated materials stored in the PBRF Hot Laboratory facilities.

TECHNICAL SPECIFICATIONS License TR-3, Amendment 13 Page 1 of 23 License R-93, Amendment 9

1.1.9 Surveillance Frequency: Surveillance frequency is the interval at which surveillances are to be performed. In cases where the elapsed interval has exceeded 100%

of the specified interval, the next surveillance interval shall commence at the end of the original specified interval. Allowable surveillance interval, as defined in ANSI/ANS 15.1 (1990) shall not exceed the following:

1. Annual (interval not to exceed 15 months).

2. Semiannual (interval not to exceed seven and one-half months).

3. Quarterly (interval not to exceed four months).

4. Monthly (interval not to exceed six weeks).

2.0 SAFETY LIMITS AND LIMITING SAFETY SYSTEM SETTINGS The Plum Brook Reactor Facility is in a decommissioning status. Since the reactors cannot be operated and there is no new or irradiated fuel present on site, there are no remaining activities that could lead to breach of a fission product barrier or could lead to an inadvertent or uncontrolled criticality. Therefore, there are no Safety Limits or Limiting Safety System Settings.

3.0 LIMITING CONDITIONS FOR DECOMMISSIONING OPERATIONS 3.1 Control of Access Applicability This specification is applicable to all activities related to the control of personnel and vehicle ingress to and egress from the restricted area.

Objective The objective of this specification is to assure that controls are established for safe access and egress of personnel, vehicles, and materials at PBRF, and to minimize the potential for unauthorized access that could lead to inadvertent exposure to radiological hazards, and to prevent inadvertent or uncontrolled release of radiological hazards from the facility.

Specification (1) Personnel shall receive radiological monitoring prior to egress from the fenced area making up the PBRF site.

(2) Whenever decommissioning activities are in progress, properly trained personnel shall be stationed to control personnel, vehicle and material entry into, and egress out of the fenced area making up the PBRF site. Only Authorized Entries shall be permitted.

TECHNICAL SPECIFICATIONS License TR-3, Amendment 13 Page 2 of 23 License R-93, Amendment 9

(3) An effective method of continuously accounting for the presence of all personnel who are within the fenced PBRF site shall be implemented.

(4) When no decommissioning activities are in progress, the PBRF fenced perimeter shall be locked. Access to keys for the PBRF fence gates shall be limited to personnel authorized by the NASA Decommissioning Project Manager.

(5) Written procedures shall be implemented for control of issuance of keys. If key control is lost, perimeter fence locks shall be changed and security reestablished as soon as practicable.

Bases The restrictions and limitations of Specification 3.1 are necessary to provide assurance that effective PBRF site security and control of personnel exposure to radiological and industrial hazards is maintained. Additionally, the monitored egress of personnel from the site is necessary to assure that no uncontrolled radiological hazards inadvertently leave PBRF.

3.2 Alarm Response Applicability This specification applies to the alarm functions needed to identify the presence of intrusion of ground water into areas of the facility where such intrusion could result in the flow of radioactive contamination into the plant liquid discharge pathways.

Objective The objective of this specification is to minimize the potential for ground water intrusion causing the movement of radioactive contamination into the facility storm drain discharge paths.

Specification (1) Any area of the reactor facility that contains an operable sump pump and has removable surface contamination on the surrounding floor area in excess of 1000 disintegrations per minute per 100 cm2 beta-gamma or in excess of 20 disintegrations per minute per 100 cm2 alpha, shall be equipped with an alarm that will detect the presence of a high water level in the sump. The alarm shall provide an indication of a high water level at the Reactor Security Building and at a remote manned location (typically the Plum Brook Station Communication Center). The alarms shall be operable at any time the site is not manned. If a required alarm is inoperable, restore the alarm to operable status prior to leaving the site at the end of the workday, or, prevent the associated sump pumps from automatically starting, and take action to TECHNICAL SPECIFICATIONS License TR-3, Amendment 13 Page 3 of 23 License R-93, Amendment 9

prevent the flow of water that overflows the sump from being discharged to the plant drain systems prior to sampling as required in 3.2(4) below.

(2) Upon receipt of an alarm, the PBRF Management shall be immediately notified.

PBRF Management shall, upon notification, have a visual inspection performed of the affected area within four hours.

(3) If a high water level exists and the sump pump can be restored to a condition that will control the water level prior to overflow of the sump, then restore the pump to operation and reduce the water level.

(4) If the sump has overflowed onto an area with loose surface contamination in excess of that specified in 3.2(1), or if the pump cannot be restored to an operable condition, secure the pump so that it cannot be started, secure the area, and do not pump out the water until it has been sampled and its radionuclide content verified to within the limits specified in 3.4(2).

Bases This specification provides assurance that radioactive contaminants in liquid effluents from the facility are maintained within the limits of specification 3.4(2). The facility sumps have been in operation since shutdown of the facility to remove groundwater that has historically intruded through the building foundation structures. These sumps discharge out where they are combined with storm water and storm drain runoff to the Pentolite Ditch. The facility has no installed radiation monitoring systems on the liquid discharge pathway; however historical sampling has demonstrated that the normal flows of water are ground water and storm water that has not been contaminated from licensed activities. If a sump overflowed in an area that is contaminated with radioactive material, the water could become contaminated.

These specifications provide controls such that the potential for contamination is minimized, and if the overflow does occur the discharge of the water to the environment will be prevented until sample and analysis show that it meets the discharge criteria.

3.3 Containment Applicability This specification is applicable to the structures and devices used to prevent the uncontrolled spread of airborne radioactivity to areas of the facility and to the environment during all decommissioning activities.

Objective The objective of this specification is to impose controls on the performance of decommissioning activities that will provide assurance that the site work force is afforded adequate protection from airborne radioactivity and the exposures to the public from TECHNICAL SPECIFICATIONS License TR-3, Amendment 13 Page 4 of 23 License R-93, Amendment 9

airborne radioactivity are in conformance with the requirements of 10 CFR 20.1101 (d) and 10 CFR 20.1302.

Specification (1) Activities that have the potential to produce an airborne radioactivity concentration of greater than one DAC in the surrounding atmosphere shall be controlled at the source with appropriate engineering controls to maintain the surrounding airborne concentrations below one DAC, or shall be performed inside of a containment device equipped with an operating HEPA filtered temporary ventilation system configured so the flow of unfiltered air is from the area outside of the containment enclosure into the enclosure.

(2) The temporary ventilation systems specified in (1) above shall be constructed of fire resistant material, shall include a device for monitoring the filters resistance to air flow, and the filter or pre-filter shall be of a fire resistant type unless the suction line is protected with a spark arrestor.

(3) Activities that have the potential to produce an airborne radioactivity concentration of greater than one DAC in the surrounding atmosphere may be performed within the Containment Vessel without the devices specified in (1) and (2) above provided the following are met:

(a) Except for brief periods to facilitate personnel and equipment transfer, the air-lock doors and the roll-up door shall be closed or covered with barrier materials such as plywood or plastic sheeting in such a manner that the free flow of air out of the Containment Vessel is inhibited, and (b) Personnel access to the Containment Vessel shall be controlled by either operation of the air lock inner and outer door interlocks and interlock alarms, or by stationing personnel at each entry who will control ingress and egress from the Containment Vessel, and (c) The condition of the Containment Vessel is maintained such that all other openings, including pipe penetrations, are closed with sheet material or closure devices that will prevent the unfiltered exchange of air from inside the Containment Vessel to the outside.

Bases This specification provides assurance that appropriate controls are imposed on activities that have the potential to produce airborne radioactivity to prevent uncontrolled releases to the environment. The Plum Brook Reactor Facility has no operable permanently installed ventilation systems, ventilation filters, or ventilation monitoring systems. However, the facility has no fuel so there is no potential for the release of fission products to the atmosphere as a result of fuel cladding failures. The majority of the radioactive source term TECHNICAL SPECIFICATIONS License TR-3, Amendment 13 Page 5 of 23 License R-93, Amendment 9

available for release to the environment was contained within the reactor vessel and associate primary systems and in storage in the Hot Dry Storage area. Decommissioning has progressed to the point that the material in Hot Dry Storage has been packaged and shipped off site and the reactor vessel internals and the reactor vessel have been nearly removed and packaged for disposal. The remaining activity is contained in the form of activated piping, activation and residual contamination products in the concrete structures (including the biological shield), and in system piping and drains contained with in the facility. Continued decontamination and removal of the structures, systems, and components containing the remaining radioactivity has the potential to produce airborne radioactivity that if uncontrolled could result in unnecessary exposure to the work force and to the off-site public. These specifications, in conjunction with compliance with the radiological controls program requirements specified in the NRC regulations in 10 CFR 20 will provide assurance that the worker and public exposure regulatory limits are met. The one DAC criteria specified for requiring containment devices is set as a conservative limit to assure that when localized airborne radioactivity is produced, the rate of exposure to this activity at the site boundary will be well below the regulatory exposure limits specified in 10 CFR 20. The criteria of paragraph (2) are provided to minimize the potential for a fire when work activities specified include flame or spark producing activities.

3.4 Radiation and Effluent Monitoring Program Applicability This specification applies to the plans and programs that are established for the control of radiation protection activities and environmental radiation monitoring activities throughout the Decommissioning Project.

Objective The objective of this specification is to assure that adequate controls are in place to assure that occupational exposure to the work force, exposures to the public from licensed activities, and radioactive materials released to the environment are maintained within the limits specified in 10 CFR 20 and are As Low As Reasonably Achievable.

Specification (1) A radiation protection program shall be established that meets the requirements of 10 CFR20.1101 and shall be implemented through written plans and procedures.

(2) Liquid effluents from the facility shall be sampled prior to release and verified to meet the radionuclide concentration limits specified in 10 CFR 20, Appendix B, Table 2, Column 2.

(3) An environmental media sampling and analysis program shall be established and implemented through written plans and procedures that achieve the following:

TECHNICAL SPECIFICATIONS License TR-3, Amendment 13 Page 6 of 23 License R-93, Amendment 9

(a) Establish lower limits of detection for expected contaminants in environmental water, soil, sediment, and air samples.

(b) Establish environmental sampling protocols that will provide assurance that average concentrations in liquid effluents have met the criteria in Specification (2) above and that effluents to the air have met the limits of 10 CFR 20.1302 and 10 CFR 20.1101(d).

(4) An air particulate sampler shall be operated continuously near each side of the perimeter fence around the 27-acre fenced area at any time decommissioning activities are in progress. If the installed sampler is inoperable, a portable sampler shall be situated in the same general area until the installed monitor is returned to operable status.

Bases The specifications in section 3.4 assure that all licensed activities carried out at the Plum Brook Reactor Facility are controlled in such a manner that radiation exposure to the work force and the members of the public and the radiological impact on the surrounding environment are kept within the regulatory limits specified in 10 CFR 20.

Specification (1) invokes the requirements of 10 CFR 20.1101 to establish and implement a documented plan for the control of radiation protection activities. It includes implementation of the regulatory requirement to maintain radiation exposures As Low As Reasonably Achievable (ALARA). The scope of a plan meeting the requirements of 10 CFR 20.1101 will include implementing the applicable requirements for controlling access, posting of areas, surveys and survey documentation, control of exposure, monitoring of exposure, control of radioactive materials, monitoring and control of effluents, and record keeping.

Specifications (2) and (3) provide assurance that limits are established on effluents from the facility to assure that the public exposure regulatory limits are met, including the ALARA criteria, and that effluents are properly monitored for compliance.

4.0 SURVEILLANCE REQUIREMENTS 4.1 Control of Access Applicability This specification applies to the surveillance requirements for the access control program.

Objective The objective of this specification is to assure that that the specifications of Section 3.1 are satisfied.

TECHNICAL SPECIFICATIONS License TR-3, Amendment 13 Page 7 of 23 License R-93, Amendment 9

Specification (1) At the end of each working day, all perimeter fence gates shall be checked and verified to be locked.

(2) At the end of each working day, all keys that were issued during the day to allow controlled access through perimeter gates shall be verified to be returned to the issue control point and logged back into the issue record.

Bases The surveillance requirements of section 4.1 provide assurance that common industrial security measures are established around the Plum Brook Reactor Facility such that unauthorized entry that could lead to inadvertent exposure to radiological hazards do not occur. These surveillances performed in conjunction with the requirements of the radiation protection program specified in section 3.4 will assure that the access control and radiological monitoring requirements of section 3.1 are satisfied.

4.2 Alarm Response Applicability This specification applies to the surveillance of alarms that are required to be functional.

Objective The objective of this section is to establish surveillance requirements that will assure the operability of alarms needed to provide warnings of abnormal conditions.

Specification (1) Each alarm required by section 3.2 shall be verified to be operable at least monthly.

Bases The surveillance requirements of section 4.2 provide assurance that alarms are functional and capable of detecting the intrusion of ground water into areas of the facility that would present the potential for release of radioactive material into the liquid discharges to the environment.

TECHNICAL SPECIFICATIONS License TR-3, Amendment 13 Page 8 of 23 License R-93, Amendment 9

4.3 Containment Applicability This specification applies to the surveillance of containments, containment devices, and the containment vessel when these are required for the control of airborne radioactivity.

Objective The objective of this section is to establish surveillance requirements that will assure the operability of structures and devices needed to assure that airborne radioactivity is controlled within the limits specified.

Specification (1) Each containment device required in accordance with section 3.3 (1) and (2) shall be inspected upon startup and at least daily when in use to verify the following:

a. The enclosure is intact and the flow of unfiltered air is from the outside of the containment into the enclosure

b. The temporary ventilation device is operable or operating with filter differential pressures within the manufacturers specified parameters.

(2) When the Containment Vessel serves as containment for the control of airborne radioactivity in accordance with section 3.3 (3), perform the following:

a. At least daily, verify that air-lock doors and roll-up door are closed or covered with barrier materials.

b. At least daily, perform a visual inspection of the Containment Vessel to verify that there are no pathways open to the environment other than those open for brief periods of time to allow transfer of material and personnel.

c. At least daily, verify the operability of the airlock door interlock alarms unless personnel are stationed to control access through the doors.

Bases The surveillance requirements of section 4.3 provide assurance that containments are capable of performing their intended function of controlling the release of airborne radioactivity generated by decommissioning activities.

TECHNICAL SPECIFICATIONS License TR-3, Amendment 13 Page 9 of 23 License R-93, Amendment 9

4.4 Radiation and Effluent Monitoring Program Applicability This specification applies to the surveillances necessary to assure that the components required for implementation of the radiation protection and environmental effluent monitoring program are functional.

Objective The objective of this specification is to assure that adequate controls are in place to assure that occupational exposure to the work force, exposures to the public from licensed activities, and radioactive materials released to the environment are maintained within the limits specified in 10 CFR 20 and are As Low As Reasonably Achievable.

Specification (1) At least weekly, verify the operability of the fence line air particulate samplers.

(2) The environmental sampling protocols of the environmental media sampling and analysis program shall be implemented.

Bases The surveillance program required by section 4.4 in conjunction with the radiological protection program requirements of 10 CFR 20 invoked by section 3.4 provide assurance that adequate controls are in place to assure that the exposure controls and effluent restrictions of 10 CFR 20 are satisfied.

5.0 SITE FEATURES The Plum Brook Reactor Facility consists of a 27-acre fenced in facility that when in operation contained a 60 Mega-Watt test Reactor and a 100 Kilo-Watt swimming pool type research reactor. The 27-acre fenced in area constitutes the Restricted Area as defined in 10 CFR 20.1003. The restricted area is surrounded by the Plum Brook Station, a 5400-acre fenced in test site owned by the National Aeronautics and Space Administration (NASA).

NASA maintains and controls access to the Plum Brook Station. The reactors are undergoing decommissioning and the site is in the process of radiological remediation. The reactors are defueled and no reactor fuel, neither new nor irradiated, remains on site. The reactors have been shutdown since 1973.

The Containment Vessel is a structure that covers the main test reactor. It serves as a barrier to prevent the uncontrolled migration of radioactive material from the reactor systems to the environment. There are no active permanently installed ventilation systems or ventilation system filters or monitoring systems remaining at the facility. The reactor vessel has been TECHNICAL SPECIFICATIONS License TR-3, Amendment 13 Page 10 of 23 License R-93, Amendment 9

nearly completely removed and the majority of the plant systems that supported the reactor have been removed. Equipment that has been removed was sectioned, packaged, and has been shipped offsite for disposal or is packaged and awaiting shipment off site. The radioactive material that was stored in the Hot Laboratory and the Hot Dry Storage Area have also been removed and packaged for offsite disposal.

There are no systems, structures, or components remaining that perform a safety related function of maintaining fission product barriers or criticality control. In its present condition, there is no potential for an inadvertent or uncontrolled criticality.

A radiological controls program is implemented through written plans and procedures that provide for effective control of radiological hazards and for monitoring for the potential for offsite exposure of the public and environment from radiological hazards.

The decommissioning program is fully described in the NRC approved Decommissioning Plan for the Plum Brook Reactor Facility. The program for final radiological surveys to demonstrate compliance with the 10 CFR 20 License Termination Criteria is fully described in the Final Status Survey Plan for the Plum Brook Reactor Facility.

Activities in violation of limiting conditions for the conduct of activities established in the technical specification unless prompt remedial action is taken.

TECHNICAL SPECIFICATIONS License TR-3, Amendment 13 Page 19 of 23 License R-93, Amendment 9

An observed inadequacy in the implementation of administrative or procedural controls such that the inadequacy causes or could have caused the existence or development of an unsafe condition with regard to facility operations.

(2) A written report within 30 days to the NRC of:

(a) Permanent changes in the facility organization management personnel (Level 1 or 2).

(b) Significant changes in the accident analysis as described in the decommissioning plan safety analysis.

6.13 RECORDS Records may be in the form of correspondence, reports, logs, data sheets, or other suitable forms. The required information may be contained in single or multiple records or a combination thereof.

6.13.1 Retention of Records The following records are to be maintained for a period of at least five years or for the life of the component involved if less than five years:

(1) Facility decommissioning operations (but not including supporting documents such as check lists, log sheets, etc which shall be maintained for a period of at least one year.)

(2) Principal maintenance and project activities (3) Reportable occurrences (4) Surveillance activities required by the technical specifications (5) Reactor facility radiation and contamination surveys where required by applicable regulations (6) Approved changes in operating procedures (7) Records of meetings and independent examination reports of the review and independent examination group TECHNICAL SPECIFICATIONS License TR-3, Amendment 13 Page 20 of 23 License R-93, Amendment 9

6.13.2 Records to be Retained for the Lifetime of the Facility:

NOTE: Applicable annual reports, if they contain all of the required information, may be used as records in this section.

(1) Air and liquid radioactive effluents released to the environment.

(2) Off-site environmental monitoring surveys required by the Technical Specification (3) Radiation exposure for all personnel monitored.

(4) Drawings of the reactor facility.

(5) Records of disposal of licensed material.

6.14 HIGH RADIATION AREA 6.14.1 Access Controls Pursuant to 10 CFR 20, in lieu of the control device or alarm signal, each high radiation area as defined in 10 CFR 20, shall be barricaded and conspicuously posted as a high radiation area and entrance thereto shall be controlled by requiring issuance of a Radiation Work Permit (RWP). Individuals qualified in radiation protection procedures (e.g. Health Physics personnel) or personnel continuously escorted by such individuals may be exempt from the RWP issuance requirement during the performance of their assigned duties in high radiation areas with exposure rates equal to or less than 1000 mR/hr, provided they are otherwise following plant radiation protection procedures for entry into such high radiation areas. Any individual or group of individuals permitted to enter such areas shall be provided with or accompanied by one or more of the following:

(1) A radiation monitoring device which continuously indicates the radiation dose rate in the area, or (2) A radiation-monitoring device, which continuously integrates the radiation dose rate in the area and alarms when a pre-set integrated dose is received. Entry into such areas with this monitoring device may be made after the dose rate level in the area has been established and personnel have been made knowledgeable of them, or (3) A health physics qualified individual (i.e. qualified in radiation protection procedures) with a radiation dose rate monitoring device who is responsible for providing positive control over the activities within the area and shall perform periodic radiation surveillance at the frequency specified by the facility Health Physics staff in the RWP.

TECHNICAL SPECIFICATIONS License TR-3, Amendment 13 Page 21 of 23 License R-93, Amendment 9

6.14.2 Control of High Radiation Areas In addition to the requirements of 6.14.1, areas accessible to personnel with radiation levels greater than 1000mR/hr at 45 cm (18 inches) from the radiation source or from any surface, which the radiation penetrates, shall be provided with locked enclosures to prevent unauthorized entry, and the keys shall be maintained under the administrative control of health physics. Enclosures shall remain locked except during periods of access by personnel under an approved RWP, which shall specify the dose rate levels in the immediate work area and the maximum allowable stay times for individuals in the area. Direct or remote continuous surveillance (such as the use of closed circuit TV cameras) may be used by personnel qualified in radiation protection procedures in lieu of the stay-time specification of the RWP in order to provide positive exposure control over the activities within the area.

For individual areas accessible to personnel with radiation levels of greater than 1000 mR/hr that are located within large areas, where no enclosure exists for purposes of locking, and no enclosure can be reasonably constructed around the individual areas, then that area shall be barricaded, conspicuously posted, and a flashing light shall be activated as a warning device whenever the dose rate in the area exceeds or will shortly exceed 1000 mR/hr.
