Potential Reactivity Worth of an Experiment - The potential reactivity worth of an experiment is the maximum absolute value of the reactivity change that would occur as a result of intended or anticipated changes or credible malfunctions that alter equipment position or configuration.

Reactivity Limits - The reactivity limits are those limits imposed on reactor core excess reactivity. Quantities are referenced specifically to a cold core (nominally 90 oF) with the effect of xenon poisoning on core reactivity accounted for if greater than or equal to 0.05% )K/K. The reference core condition will be known as the cold, xenon free critical condition.

Reactor Operation - Reactor operation means that the control rods installed in the core are not fully inserted or that the control console key is in the keyswitch. Reactor operation is not considered possible when there are less than six standard fuel elements in addition to the four control elements that house the control rods on the grid plate.

Reactor Safety System - The reactor safety system is that combination of safety channels and associated circuitry which forms the automatic protective system for the reactor or provides information which requires manual protective action to be initiated.

Reactor Scram - Shutoff of electrical current to the rod holding magnets and subsequent insertion of the rods into the core by gravity.

Reactor Secured - Reactor Secured is defined as follows:

1. The full insertion of all control rods has been verified;
2. The control console key is removed; and
3. No operation is in progress which involves moving fuel elements to or from the core, moving reflector elements to or from the core, the insertion, or removal of secured experiments from the core, or control rod maintenance.

Shim-Safety Rod - A shim-safety rod is a control rod fabricated from either borated stainless steel or a boron-aluminum alloy which is used to compensate for fuel burnup, temperature, and poison effects. A shim safety rod is magnetically coupled to its drive unit allowing it to perform the function of a safety rod when the magnet is deenergized.

Static Reactivity Worth - The static reactivity worth of an experiment is the absolute value of the reactivity change which is measurable by calibrated control rod comparison methods between two defined terminal positions or configurations of the experiment. For moveable experiments, the terminal positions are fully removed from the reactor and fully inserted or installed in the normal functioning or intended position.

Amendment No. 48 FNR Tech. Specs.

Bases:

The potential radiation exposure to persons at the operations boundary following an accident releasing fission products within the confinement building has been evaluated. The evaluation used a leakage rate from the confinement building of 10% of the building volume per day, and concluded that the accident doses would be acceptable. Conformance to Specifications 3.3.1 and 3.3.2 will assure that the building leak rate will not exceed the leak rate used in the evaluation.

The 1.0 mrem/hr setpoint for the facility exhaust radiation monitor provides a mechanism for isolating the building ventilation system in the event of a significant release of radioactive material into the reactor building. This setpoint, for the detector location involved, represents a gamma emitting nuclide concentration of 10-3 to 10-4 microcuries/cc of building air.

By requiring that the access doors and equipment hatch remain closed, except for brief, attended periods to permit personnel or equipment passage, the integrity of the confinement will be maintained at or above the level assumed in the Hazards Summary Report, and the release of radioactive material will be minimized.

  • service, THEN licensed activity involving radioactive materials that could produce radiation
  • levels in areas accessible to individuals in excess of 100 mrem in 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> at 30 centimeters *

(measured from an accessible surface that emits radiation) shall be stopped in a safe

  • condition AND shall not resume until the affected local area radiation monitor is restored to
  • an operating condition.
  • Bases:

The limits established in this specification incorporate a dilution factor of 400 for effluents released through the exhaust stacks. This dilution factor was calculated from actual FNR site meteorological data and represents the lowest dispersion factor determined and the highest frequency of wind in any sector. Because of the use of the most conservative measured values of wind directional frequency and dispersion factors, this dilution factor will assure that concentrations of radioactive material in unrestricted areas around the FNR site will be far below the limits of 10CFR20.

The pool floor area radiation monitor provides local indication of elevated levels of radiation

  • from the irradiated materials in the reactor pool.
  • The requirements of this specification are considered adequate to assure proper monitoring of
  • area radiation and airborne radioactivity levels within the reactor building.
  • 3.6 Liquid Effluents Applicability:

This specification applies to the monitoring of radioactive liquid effluents from the FNR.

Objectives:

The objective is to assure that exposure to the public resulting from the release of liquid effluents will be minimized.

Specification:

1. The concentration of radioactive materials in the effluent released from the facility liquid waste system to the city of Ann Arbor sanitary sewer system shall be readily soluble (or readily dispersible biological material) in water and shall not exceed 315 times the concentrations specified in 10CFR20, Appendix B, Table 3, Releases to Sewers.
2. The amount of liquid discharged shall be limited to the equivalent of 3,000 gallons of liquid at the concentration limit specified in 3.6.1 each day.
3. Liquids from the facility's radioactive liquid waste system shall not be discharged into the storm drain system.

Amendment No. 48 FNR Tech. Specs.

Bases:

All radioactive liquid effluents are collected in a series of three, 3,000 gallon, coated, steel retention tanks, and they are normally recycled to the reactor pool to make up for surface evaporation. However, after sampling, analysis, and dilution, if the concentration of radioactivity is less than the limit of 10CFR20, liquid effluents can be discharged to the sanitary sewer system.

In the past, less than 50 retention tank discharges per year have been required. During 1970, the North Campus water released into the sanitary sewer system averaged 946,000 gallons per day. This provides a daily dilution factor of 315 for a 3,000 gallon waste tank, which assures that there will be no significant exposure to the public from radioactive waste discharged to the sanitary sewer system.

3.7 Limitations of Experiments Applicability:

  • These limits established the administrative constraints for the lowest functional capability or
  • performance level for equipment associated with and operational characteristics of experiments
  • conducted in the Ford Nuclear Reactor. These limits have been removed from the Technical
  • Specifications.

4.7 Fission Density Limits Applicability:

  • The surveillance requirement for the fission density limit has been removed from the Technical
  • Specifications.
  • Bases:
  • On January 29, 2004, the license for the Ford Nuclear Reactor was modified with the following

5.0 DESIGN FEATURES 5.1 Site Description The Ford Nuclear Reactor (FNR) is located on the North Campus of the University of Michigan at Ann Arbor, Michigan. The North Campus area is under the administrative control of the Regents of the University of Michigan.

The North Campus is a tract of nearly 900 acres, about 1-1/2 miles northeast of the center of Ann Arbor. It is bounded on the north by Plymouth Road and on the south by Glazier Way. A VA hospital and some apartments are south of Glazier Way. Apartments are located north of Plymouth Road. Open land and the Arborcrest Cemetery lie to the east. To the west are University athletic fields, municipal parks and a wooded ridge. The Huron River flows through land bordering the area on the west and south and some marsh land lies adjacent to the river on the south.

The reactor building is located near the center of the North Campus area. No housing or buildings containing housing facilities are erected within 1500 feet of the reactor.

The University of Michigan controls all the land within 1500 feet of the reactor site, with the exception of a small portion of the highway right of way along Glazier Way on the southeast and the Arborcrest Cemetery located 800 feet to the east of the site.

The reactor site consists of all the land 500 feet to the east, 1000 feet to the west and north and 1200 feet to the south. The boundary of this area consists of roadways around the site whose traffic flow can be controlled should such control be desirable.

The reactor restricted area consists of the reactor building and the contiguous Phoenix Memorial Laboratory (PML). The reactor building is the operations boundary and the emergency planning zone.

5.2 Reactor Fuel The license for the Ford Nuclear Reactor does not allow for the possession of reactor fuel.

  • 5.3 Reactor Building The reactor building is a windowless, four story, reinforced concrete building with 12 inch walls structurally integral with the footings and foundation mats. The building is approximately 69 feet wide x 68 feet long x 70 feet high with approximately 44 feet exposed above grade. The building has the following general features:
1. The reactor is housed in a closed room designed to restrict leakage.
2. The reactor room is equipped with a ventilation system designed to exhaust air or other gases present in the building atmosphere into an exhaust stack which exhausts a minimum of 54 feet above ground level.
3. The ventilation system provides ventilation for certain storage and experimental facilities and exhausts these a minimum of 54 feet above ground level.

Amendment No. 48 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT NO. 48 TO FACILITY OPERATING LICENSE NO. R-28 UNIVERSITY OF MICHIGAN FORD NUCLEAR REACTOR DOCKET NO. 50-02

1.0 INTRODUCTION

By letters dated September 08, 2005, February 28, 2006, and April 6, 2006, the University of Michigan (the licensee) submitted a request to change the Technical Specifications (TSs) for the Ford Nuclear Reactor (FNR). The requested change would eliminate those specifications which are no longer applicable for the facility not licensed to possess reactor fuel. Each change is discussed below.

2.0 EVALUATION 2.1 Technical Specification 2.1, Safety Limits As of December 16, 2003, the FNR no longer has reactor fuel on site and on January 29, 2004, the license for the FNR was modified to no longer permit operation of the reactor and to not allow fuel elements to be placed in the reactor grid. As the Safety Limits in the TS were for the protection of the cladding integrity of the fuel during reactor operation, the licensee is requesting that TS 2.1, Safety Limits, and its subsets TS 2.1.1, Safety Limits in the Forced Convection Mode, and TS 2.1.2, Safety Limits in the Natural Convection Mode be removed from the TS.

The objectives of TS 2.1.1 and 2.1.2 are to assure the integrity of the fuel cladding during reactor operation. The licensee is requesting to delete TS 2.1.1 and 2.1.2 based on the FNR operating license, modified on January 29, 2004, which states: The licensee shall not operate the reactor nor place fuel elements in the reactor grid, and which removed the condition in the operating license allowing for the possession of reactor fuel under 10 CFR Part 70. Currently, FNR has no reactor fuel. The NRC staff concludes that since the FNR does not have any fuel and that the operating license does not allow for the FNR to possess any fuel this change is acceptable.

2.2 Technical Specification 2.2, Limiting Safety System Settings

The objective of TS 2.2 and its subsets TS 2.2.1, Limiting Safety System Setting in the Forced Convection Mode, and TS 2.2.2, Limiting Safety System Setting in the Natural Convection Flow Mode, is to prevent exceeding a safety limit and assure the cladding integrity of the reactor fuel during reactor operation. The licensee is requesting to delete TS 2.2, TS 2.2.1, and TS 2.2.2 based on the FNR operating license, modified on January 29, 2004, which states: The licensee shall not operate the reactor nor place fuel elements in the reactor grid, and which removed the condition in the operating license allowing for the possession of reactor fuel under 10 CFR Part

70. Currently, FNR has no reactor fuel. The NRC staff concludes that since the FNR does not have any fuel and that the operating license does not allow for the FNR to possess any fuel this change is acceptable.

2.3 Technical Specifications 3.1, Reactivity Limits, and 4.1, Reactivity Limits The objective of TS 3.1 is to assure that the reactor can be controlled and shutdown at all times and that the safety limits will not be exceeded. The licensee is requesting to delete TS 3.1 based on the FNR operating license, modified on January 29, 2004, which states: The licensee shall not operate the reactor nor place fuel elements in the reactor grid, and which removed the condition in the operating license allowing for the possession of reactor fuel under 10 CFR Part

70. Currently, FNR has no reactor fuel. The NRC staff concludes that since the FNR does not have any fuel and that the operating license does not allow for the FNR to possess any fuel or operate the reactor, this change is acceptable.

The objective of TS 4.1 is to assure reactivity limits of TS 3.1 are not exceeded. The licensee is requesting to delete TS 4.1 based on the FNR operating license modified on January 29, 2004, which states: The licensee shall not operate the reactor nor place fuel elements in the reactor grid, and the condition in the operating license allowing for the possession of reactor fuel under 10 CFR Part 70 be removed. Currently, FNR has no reactor fuel. The NRC staff concludes that since the FNR does not have any fuel, the operating license does not allow for the FNR to possess any fuel, and TS 3.1 has been deleted this change is acceptable.

2.4 Technical Specifications 3.2, Reactor Safety System, and 4.2, Reactor Safety System The objective of TS 3.2 is to specify the lowest acceptable level of performance or the minimum number of acceptable components for the reactor safety system and other safety related instrumentation. The request to delete TS 3.2 is based on the FNR operating license, modified on January 29, 2004, which states: The licensee shall not operate the reactor nor place fuel elements in the reactor grid, and which removed the condition in the operating license allowing for the possession of reactor fuel under 10 CFR Part 70.

In addition, the licensee is requesting that the requirements for area radiation monitoring identified in TS 3.2 be moved to the revised Limited Condition of Operation (LCO) Section 3.5, Radiation Monitoring, and the requirements of the facility radiation exhaust monitor identified in TS 3.2 be moved to the revised LCO Section 3.3, Confinement.

Currently, FNR has no reactor fuel. The NRC staff concludes that since the FNR does not have any fuel, the operating license does not allow for the FNR to possess any fuel or operate the reactor, and the requirements for radiation monitoring and the requirements for facility radiation exhaust monitor identified in TS 3.2 are moved to TS 3.5 and TS 3.3 respectively, this change is acceptable.

The objective of TS 4.2 is to assure that the reactor safety system is operable as required by TS 3.2. The licensee is requesting to delete TS 4.2 based on the FNR operating license modified on January 29, 2004, which states: The licensee shall not operate the reactor nor place fuel elements in the reactor grid, and the condition in the operating license allowing for the possession of reactor fuel under 10 CFR Part 70 be removed. Currently, FNR has no reactor fuel. The NRC staff concludes that since the FNR does not have any fuel, the operating license does not allow for the FNR to possess any fuel or operate the reactor, and TS 3.2 has been deleted this change is acceptable 2.5 Technical Specifications 3.3, FNR Confinement, and 4.3, FNR Confinement The objective of TS 3.3 is to assure that the FNR building confinement integrity is maintained during reactor operation and to minimize the release of airborne radioactive materials from the reactor building. With the permanent cessation of operations and to facilitate equipment access for decommissioning, the licensee is requesting to revise the objective of TS 3.3, FNR Confinement to:

1. To assure that automatic protective action is initiated to limit the release of radioactive effluents from the reactor building when required.
2. To provide an audible alarm within the reactor building to initiate evacuation when required.
3. To assure that the FNR reactor building confinement integrity is maintained when required.

The licensee is also requesting that the applicability of TS 3.3, FNR Confinement, and its surveillance be revised to remain in effect until that point during decommissioning where the removal of radioactive materials from the facility reduces the quantity of radioactive materials in unsealed form, on foils or plated sources, or sealed in glass contained in the reactor building exceeds 1.5 x 10-2 times the quantities in 10 CFR 30.72, Schedule C - Quantities of Radioactive Materials Requiring Consideration of the Need for an Emergency Plan for Responding to a Release. The 1.5 x 10-2 times is to account for the difference between the 1 rem limit in 10 CFR 30.(i)(1)(i) and the lower 15 mrem limit for an Unusual Event (the lowest level of emergency for a non-power reactor). Once the quantity of radioactive materials in unsealed form, on foils or plated sources, or sealed in glass contained in the reactor building has been reduced to less than 1.5 x 10-2 times the quantity of materials listed in 10 CFR 30.72, Schedule C, then the need for the automatic protective actions associated with the reactor building exhaust radiation monitor or the continuous air monitor may be removed. The licensee recognizes that the requirements of 10 CFR 20.1301, Dose Limits for Individual Members of the Public would continue to apply, subject to the allowances of 10 CFR 20.1302, Compliance with Dose Limits for Individual Members of the Public.

The new TS 3.3, FNR Confinement, will continue to specify that when the radiation level in the FNR ventilation exhaust duct is equal to or greater than 1mR/hr, automatic protective actions occur to isolate the building ventilation system. The new TS 3.3, FNR Confinement, will: 1) provide a mechanism to isolate the FNR building ventilation system in the event of a significant release of radioactive material into the reactor building; 2) maintain the integrity of confinement at or above the level assumed in the Hazardous Summary Report and minimize the release of radioactive material by requiring that access doors and equipment access hatch remain closed except for brief attended periods to permit personnel or equipment passage; 3) assure that the building leakage rate will not exceed the leakage rate used in the evaluation of potential

radiation exposure to persons at the operations boundary following an accident releasing fission products within the confinement building; 4) add the requirement of a radiation instrument in the building air exhaust plenum to assure that automatic protective actions for confinement occur should there be a release of radioactive material equal to or greater that 1 mR/hr from the FNR building and that an audible alarm is sounded in the reactor building to initiate evacuation (the audible alarm requirement was moved to this section from TS 3.2, Reactor Safety System).

The replacement of the applicability and objectivity for TS 3.3 is based on: 1) the FNR operating license modified on January 29, 2004 which states: The licensee shall not operate the reactor nor place fuel elements in the reactor grid, 2) the condition in the operating license which no longer allows for the possession of reactor fuel under 10 CFR Part 70; 3) the requirements of effluent monitoring which has been moved to TS 3.5; 4) the addition of a radiation instrument to monitor the building air exhaust plenum for effluent monitoring and an audible alarm should protective actions occur; and 5) FNR has no reactor fuel.

The NRC staff concludes that since the FNR does not have any fuel, the operating license does not allow for the FNR to possess any fuel, the radiation instrument identified in TS 3.2 is moved to TS 3.3, and that there is a gamma radiation detector to monitor radioactive effluents and cause automatic protective actions to limit the release of radioactive effluents from the reactor building, this change is acceptable.

The licensee is requesting to revise the applicability and objective of TS 4.3, FNR Confinement, to reflect the applicability and objective of revised TS 3.3, FNR Confinement. The new TS 4.3, FNR Confinement will assure that the closure devices for the building openings are in satisfactory condition to provide adequate confinement of any airborne radioactivity released into the building. In addition, the licensee is requesting to add surveillance requirements to assure that the radiation detector used to initiate the automatic protective action is operable.

The NRC staff concludes that this change is acceptable.

2.6 Technical Specifications 3.4, Primary Coolant Conditions, and 4.4, Primary Coolant System The objective of TS 3.4 is to maintain the primary coolant in a condition to minimize the corrosion of the primary coolant system, fuel clad, and other reactor components, and to assure proper conditions of coolant for normal and emergency requirements. Currently, FNR has no reactor fuel. Based on the FNR operating license, modified on January 29, 2004, which states:

The licensee shall not operate the reactor nor place fuel elements in the reactor grid, and which removed the condition in the operating license allowing for the possession of reactor fuel under 10 CFR 70, the specifications of TS 3.4 are no longer necessary. The licensee is requesting to revise TS 3.4 to change its title, objective, and specification. The proposed title for TS 3.4 is Pool Water Conditions. The proposed objective and applicability of TS 3.4 will facilitate the detection of significant pool water leaks whenever the quantity of water in the pool is greater than 900 gallons. The NRC staff concludes that since the FNR does not have any fuel, the operating license does not allow for the FNR to possess any fuel, and the new TS will provide for continuous monitoring for pool water leakage, this change is acceptable.

The objective of TS 4.4, Primary Coolant System, is to assure high quality pool water and to detect the release of fission products from fuel elements. Based on the FNR operating license modified on January 29, 2004 which states: The licensee shall not operate the reactor nor place fuel elements in the reactor grid, and the condition in the operating license allowing for

the possession of reactor fuel under 10 CFR Part 70 be removed, the licensee is requesting to revise TS 4.4 to change its title, objective, and specification. The proposed title for TS 3.4 is Pool Water Conditions. The proposed objective and applicability of TS 4.4 will facilitate the detection of significant pool water leaks whenever the quantity of water in the pool is greater than 900 gallons. The revision to TS 4.4 is based on routine inspection of the makeup water records to provide early warning of significant pool leaks.

The NRC staff concludes that since the FNR does not have any fuel, the operating license does not allow for the FNR to possess any fuel, and that the FNR makeup water needs will be monitored over a period of time when the reactor pool is greater than 900 gallons, which will allow for detection of significant water leaks, this change is acceptable.

2.7 Technical Specification 3.5, Radiation Airborne Effluents Currently the LCO requirements for area monitoring are contained in TS 3.2, Reactor Safety System, which is being deleted from the TS. The licensee has proposed that the requirements for the area monitors be combined with the requirement in Section 3.5, Airborne Effluents, and that this section be renamed Radiation Monitoring. The applicability of the new TS 3.5 is based on monitoring of effluent releases from the FNR, area radiation levels within the reactor building, and particulate airborne activity within the reactor building to assure that the release of airborne radioactive material from the FNR is maintained below the limits established in 10 CFR Part 20 and to ensure that occupational exposures are controlled as established in 10 CFR Part 20. The licensee has proposed:

1. that the new title of TS 3.5 be Radiation Monitoring. Since this is administrative, this change is acceptable.
2. that the LCO and surveillance requirements associated with the mobile particulate monitor for the Stack 2 exhaust be removed from TS 3.5. The LCO and surveillance requirements of the Stack 2 monitors are based on monitoring radioactive effluent from a possible failure of an experiment in the pneumatic tube system. The FNR operating license, modified on January 29, 2004, states: The licensee shall not operate the reactor nor place fuel elements in the reactor grid, and removes the condition in the operating license allowing for the possession of reactor fuel under 10 CFR Part 70. The permanent cessation of operation of the reactor has eliminated the pneumatic tube system as a source of high level of radioactive effluent, and the airborne radioactivity of grid, the reactor building is monitored by the reactor building exhaust radiation monitoring system. The NRC staff concludes that this change is acceptable.
3. that an airborne particulate monitor on the first floor be added to TS 3.5 as a requirement during licensed activities which could lead to the generation of airborne radioactivity exceeding 1% of the applicable concentrations specified in 10 CFR 20, Appendix B, Table 1, Column 3, Derived Air Concentration (DAC). The addition of this requirement facilitates the removal of the Stack 2 mobile particulate air monitor. The NRC staff finds that this addition to TS 3.5 is acceptable.
4. that the LCO and the surveillance requirements for gaseous activity detectors be deleted. With the removal of all irradiated fuel from the facility and the current license modified on January 29, 2004, which states: The licensee shall not operate the reactor nor place fuel elements in the reactor grid, and which removed the condition in the

operating license allowing for the possession of reactor fuel under 10 CFR Part 70, radioactive gases such as argon-41 are no longer present and can no longer be generated as fission products or neutron activation products at the facility. The NRC staff concludes that the requirement for the gaseous activity detector systems can be removed without decreasing the safety of the facility. This change is acceptable.

2.8 Technical Specification 3.7, Limitations of Experiments The objective of TS 3.7 is to prevent damage to the reactor or excessive release of radioactive materials in the event of an experiment failure. The licensee is requesting to delete TS 3.7 based on the FNR operating license, modified on January 29, 2004, which states: The licensee shall not operate the reactor nor place fuel elements in the reactor grid, and which removed the condition in the operating license allowing for the possession of reactor fuel under 10 CFR Part

70. Currently, FNR has no reactor fuel. The NRC staff concludes that since the FNR does not have any fuel and that the operating license does not allow for the FNR to possess any fuel, this change is acceptable.

2.9 Technical Specifications 3.8, Fission Density Limit, and 4.7, Fission Density Limits The objective of TS 3.8 is to prevent fuel plate swelling which could result in clad rupture and release of radioactive fission products. The objective of TS 4.7 is to assure that the fission density limits of TS 3.8 are not exceeded. The licensee is requesting to delete TS 3.8 and 4.7 based on the FNR operating license, modified on January 29, 2004, which states: The licensee shall not operate the reactor nor place fuel elements in the reactor grid, and which removed the condition in the operating license allowing for the possession of reactor fuel under 10 CFR Part

70. Currently, FNR has no reactor fuel. The NRC staff concludes that since the FNR does not have any fuel and that the operating license does not allow for the FNR to possess any fuel, this change is acceptable.

2.10 Technical Specifications 5.2, Reactor Fuel, and 5.4, Fuel Storage The objective of TS 5.2 is to assure that proper fuel design is used in the FNR core. The objective of TS 5.4 is to assure that adequate cooling is provided for irradiated fuel elements and fueled devices in storage. The licensee is requesting to delete TS 5.2 and 5.4 based on the FNR operating license, modified on January 29, 2004, which states: The licensee shall not operate the reactor nor place fuel elements in the reactor grid, and which removed the condition in the operating license allowing for the possession of reactor fuel under 10 CFR Part

70. Currently, FNR has no reactor fuel. The NRC staff concludes that since the FNR does not have any fuel and that the operating license does not allow for the FNR to possess any fuel, this change is acceptable.

2.11 Technical Specification 5.3, Reactor Building TS 5.0, Design Features, identifies those design features of the facility, such as materials of construction and geometric arrangements that, if altered or modified, would significantly affect safety and are not included in Sections 2, 3, or 4 of the TS. In section 5.3, Reactor Building, the licensee describes the general features of the reactor building, the reactor building ventilation system, the ventilation air intake and exhaust ducts, and various openings of the reactor building including the personnel and equipment access doors. Currently, the FNR operating license, modified on January 29, 2004, which states: The licensee shall not operate the reactor

nor place fuel elements in the reactor grid, removed the condition in the operating license allowing for the possession of reactor fuel under 10 CFR Part 70. The licensee is requesting that the design features described in TS 5.3 no longer apply when the quantity of radioactive materials in unsealed form, on foils or plated sources, or sealed in glass contained in the reactor building exceeds 1.5 x 10-2 times the quantities in 10 CFR 30.72, Schedule C - Quantities of Radioactive Materials Requiring Consideration of the Need for an Emergency Plan for Responding to a Release. This request to revise TS 5.3 is to support the decommissioning and dismantling of the FNR as described in the licensee's decommissioning plan submitted on June 23, 2004, and currently under review by the NRC staff.

The dismantling of safety related equipment or components during decommissioning are described in the decommissioning plan, submitted to the NRC for approval. The licensee is committed to the protection of the public and personnel from potentially hazardous exposures and situations resulting from the decommissioning. The NRC staff concludes that this change is acceptable.

2.12 Editorial changes The licensee made various grammatical and format changes, which resulted in the need to reissue the TS in its entirety. The licensee indicated these changes did not affect the meaning of the requirement, and therefore, the changes are acceptable.
