Enclosure 3 Description and Evaluation of the Proposed Changes LICENSE AMENDMENT REQUEST NASA requests that the Licenses TR-3 and R-93 be amended to reflect the incorporation of the Final Status Survey Plan for the Plum Brook Reactor Facility as a supplement to the Safety Analysis Report pursuant to 10 CFR 50.82(b)(5) and to allow commencement of the Final Status Survey.

HI. REASONS FOR THE PROPOSED CHANGE The current wording of Licenses TR-3 and R-93 requires submittal of the completed Final Status Survey Plan for review prior to performing the Final Status Survey. The proposed License amendment will reflect the fact that the Final Status Survey Plan has been submitted for review by the U.S. NRC and allow commencement of the Final Status Survey. In addition, the proposed amendment corrects a typographical error that appears in section 3.A.1.c of Licenses TR-3 and R-93. The Final Status Survey discussed as a 'preliminary plan' included within the Decommissioning Plan was based on early radiological characterization data and on hydro-geological data from past general area studies for the Plum Brook Station and the Sandusky, Ohio area. The Final Status Survey Plan included in this submittal is based on more extensive and more detailed radiological characterization studies performed since submittal of the original Decommissioning Plan. It includes data from areas of the facility that had not been studied in the previous characterization surveys, more extensive surveys of areas that had been previously studied, and includes dose pathway analyses using hydro-geologic data that is more specific to the Plum Brook Reactor Facility location. As a result, there have been changes to area classifications presented in the Decommissioning Plan and changes in the Derived Concentration Guideline Levels presented in the original Decommissioning Plan submittal. After U.S. NRC approval of the Final Status Survey Plan for the Plum Brook Reactor Facility, the Decommissioning Plan will be revised pursuant to paragraph 3.A. 1 of License TR-3 and License R-93 that will remove the current discussions of Final Status Surveys and refer to the approved Final Status Survey Plan.

III DESCRIPTION OF THE PROPOSED CHANGES A. Paragraph 2.A of License TR-3 is revised by changing the last sentence to read:

"The PBRF is describedin the applicationfor the full-term license dated January 10, 1964 and amendments thereto. "

This proposed change eliminates the list amendment submittals and dates of submittals for amendments 5 through 11. This list is administrative in nature and elimination of the list will make the wording of the license consistent with the wording of License R-93 for the Mock-Up Reactor.

Enclosure 3 Page I of 4

B. Paragraph 3 of Licenses TR-3 and R-93 is revised to read:

"NASA is authorized to decommission thefacility in accordancewith the Decommissioning Planfor the Plum Brook Reactor Facility approved by the Commission by issuance of license amendment datedMarch 20, 2002, as revised pursuant to paragraph3.A. 1 below, and to perform FinalStatus Surveys in accordancewith the Final Status Survey Planfor the Plum Brook Reactor Facilityas submitted by letter dated December 17, 2004, and revisedpursuantto paragraph 3.A.1 below.

This proposed change will allow performance of the Final Status Survey. In addition, the word changes recognize that the Decommissioning Plan and Final Status Survey Plan may both be revised without prior NRC approval provided conditions in paragraph 3 A. 1 are satisfied, and that activities may be performed in accordance with these plans as revised.

C. Paragraph 3.A of Licenses TR-3 and R-93 is revised to read:

"This amendment authorizes inclusion of the DecommissioningPlanfor the Plum Brook Reactor Facility and the Final Status Survey Planfor the Plum Brook Reactor Facility and their supplements as supplements to the FinalSafety Analysis Report pursuant to 10 CFR 50.82(b)(5). "

The current Licenses authorize inclusion of the Decommissioning Plan as a supplement to the Final Safety Analysis Report. This proposed change would add the Final Status Survey Plan as a supplement to the Final Safety Analysis Report.

D. Paragraph 3.A.1 of Licenses TR-3 and R-93 is revised to read:

"The licensee may make changes to the above plans and revisions without prior U.S.

NRC approvalprovided the proposed changes do not.:"

This proposed change changes the word 'plan' to 'plans', and would allow the licensee to make changes to the Final Status Survey Plan without prior U.S. NRC approval subject to the same criteria as currently applied to changes to the Decommissioning Plan.

E. Paragraph 3.A.1.c of Licenses TR-3 and R-93 is revised to read:

"increasethe derived concentrationguideline level and relatedminimum detectable concentrations (for both scan andfixed measurement methods); "

This proposed change revises the word 'fuel' to 'fixed' to correct a typographical error that appears in both License TR-3 and R-93.

Enclosure 3 Page 2 of 4

F. Paraaraph 3.A.3 of Licenses TR-3 and R-93 is revised to read:

"DELETED "

The Final Status Survey Plan required to be submitted by paragraph 3.A.3 of the current licenses has been included as part of this amendment request. In addition, characterization data necessary to support U.S. NRC approval of the Plan has been included as part of this submittal. Additional characterization data will be submitted as necessary to support future revisions to the Final Status Survey Plan as needed in accordance with proposed License Condition 3.A. 1. Therefore, the terms of this License condition are no longer needed.

IV NO SIGNIFICANT HAZARDS CONSIDERATION The proposed amendment to Licenses TR-3 and R-93 are necessary to achieve the objective of verifying that the facility has been radiologically remediated to level that would permit termination of the NRC Licenses. The proposed changes do not involve a significant hazard as shown in the following:

A. The proposed amendment to Licenses TR-3 and R-93 does not involve a significant increase in the probability or consequences of an accident previously analyzed.

The accident scenarios applicable to the decommissioning of the Plum Brook Reactor Facility are described in section 3.3 of the Decommissioning Plan for the Plum Brook Reactor. The Decommissioning Plan describes postulated events that could result in a release of radioactive materials from the site and analyzes the radiation dose consequences of these events and demonstrates that no adverse public health and safety impacts are expected from these events.

Performance of Final Status Surveys in accordance with the U.S. NRC approved Final Status Survey Plan is a continuation of decommissioning and is an activity that involves measurements and analysis of residual radioactivity in areas in which decommissioning has been already been performed. It is a process used to confirm that radioactivity has been removed to achieve the acceptance criteria specified in 10 CFR 20, Subpart E. Since these survey activities will be performed in areas where other decommissioning activities are already complete, there is no credible event that could initiate the analyzed accidents. Further, these activities will be performed in areas where structures, systems, and components have been isolated or segregated from other parts of the facility where decommissioning activities are still in progress and will have no impact on these other decommissioning activities. Therefore, the proposed amendment will have no affect on the probability or consequences of accidents previously analyzed.

Enclosure 3 Page 3 of 4

B. The proposed amendment to Licenses TR-3 and R-93 will not create the possibility of a new or different kind of accident from any accident previously evaluated.

Accidents previously analyzed in the Decommissioning Plan assess different scenarios that could cause the dispersion of radioactive material to the environment. These scenarios arise from dismantlement activities associated with the decommissioning. These activities will continue as described in the Decommissioning Plan and will be accompanied by radiological survey activities done in accordance with the approved Final Status Survey Plan. The survey activities will introduce no new processes that could result in dispersion of radioactive material to the environment. The methods and processes used for control of work activities and for control and monitoring of radioactivity will remain the same as those used prior to this amendment. Therefore, no new or different types of accidents are created by this proposed amendment.

C. The proposed amendment to Licenses TR-3 and R-93 will not involve a significant reduction in a margin of safety.

As discussed previously, the activities that will be performed at the facility are as previously described and evaluated in the accident analyses presented in the Decommissioning Plan. The area classifications used in designing Final Status Surveys and the Derived Concentration Guideline Levels used for evaluating areas for release have been revised based on additional characterization survey data and additional hydro-geological data that were not available when the preliminary plan was presented in the Decommissioning Plan. Using the submitted Final Status Survey Plan, areas have been classified, surveys will be designed, and release limits will be calculated using the most current data, and using methodology that is consistent with the methodology previously applied.

The radiological criteria to be used in applying for termination of the NRC Licenses will remain the same as originally proposed and are consistent with the criteria of 10 CFR 20 Subpart E. Therefore, the margins of safety applicable to assessing the long term dose to member of the public from exposure to the facility after termination of the license remain unchanged. In addition, since this amendment does not impact any previously reviewed accident analyses as previously discussed, no margins of safety are affected by this proposed amendment.

IV IMPLEMNTATION NASA requests that the amendment become effective as of the date of issuance.
