Subject:

Plum Brook Reactor Facility, Request for Amendment to Licenses Nos. TR-3, Docket No. 50-30 and R-93, Docket No, 50-185 The following request is affirmed under 28 USC Section 1746.NASA requests that Licenses TR-3 and R-93 be amended as described in the enclosures to this letter. The proposed amendments will add a condition to each license requiring NASA to assess the residual activity and demonstrate that the stream bed and banks of Plum Brook between the boundary of Plum Brook Station and Sandusky Bay meet the license termination criteria specified in 10 CFR 20.1402 for unrestricted use prior to terminating Licenses TR-3 and R-93.This application has been reviewed pursuant to 10 CFR 50.91 (a)(1) and an analysis supporting a determination of no significant hazards is included.

NASA requests that the amendment be made effective upon issuance.

The enclosed License Amendment Request is true and correct to the best of my knowledge and belief. I declare under penalty of perjury that the foregoing is true and correct. Executed this 9 th day of January 2009.Should you have any questions or need additional information, please contact Mr. Keith Peecook, NASA Plum Brook Station, 6100 Columbus Avenue, Sandusky, Ohio 44870, at (419) 621-3277.Sincerely, Thomas W.

Description and Evaluation of the Proposed Changes Proposed Amended License TR-3 Proposed Amended License R-93 cc: USNR/C. J. Glenn (FSME)USNRC/J. Webb (FSME)USNRC/W. G. Snell (R.III/DNMS/DB)

ODH/R. E. Owen ODH/R. M. Snee ODH/M. J. Rubadue Enclosure 1 Description and Evaluation of the Proposed Chances I LICENSE AMENDMENT REQUEST NASA requests that a new paragraph number 4 be added to Licenses TR-3 and R-93 requiring that NASA assess the residual activity and demonstrate that the stream bed and banks of Plum Brook between Plum Brook Station boundary and Sandusky Bay meet the radiological criteria for unrestricted use specified in 10 CFR 20.1402 prior to terminating Licenses TR-3 and R-93. The existing paragraph 4 of both licenses will be renumbered as paragraph 5.1I REASONS FOR THE PROPOSED CHANGE The license condition added by this proposed amendment will provide assurance that the National Aeronautics and Space Administration performs assessments of the residual radioactivity in the offsite areas in Plum Brook. The assessments will demonstrate that termination of the Licenses for the Plum Brook Reactor Facility will be protective of the public health and safety, will be in conformance with the radiological criteria specified in 10 CFR 20.1402 for unrestricted use, and will be ALARA.III DESCRIPTION OF THE PROPOSED CHANGES A new paragraph 4 is added to Licenses TR-3 and R-93 that reads as follows: "4. Prior to termination of this license, NASA shall assess the residual activity in Plum Brook between the Plum Brook Station and Sandusky Bay and demonstrate that the area meets the radiological criteria Jor unrestricted use specified in 10 CFR 20.1402." The existing paragraph 4 which states: "4 This license amendment is efJ~ctive as of its date of issuance." is renumbered as paragraph 5.IV NO SIGNIFICANT HAZARDS CONSIDERATION The proposed amendment to Licenses TR-3 and R-93 was recommended by the NRC staff to provide assurance that the areas of Plum Brook which are outside of the boundaries of the Plum Brook Reactor Facility and the NASA owned Plum Brook Station meet the regulatory criteria for unrestricted use prior to termination of the Enclosure I Page 1 of3 Facility 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 al'd safety impacts are expected from these events.Radiological assessment of the residual r'adioactivity in environmental areas involves sampling and performance of surveys. Spot remediation of some areas will be performed to assure that the ALARA criteria are met. These activities will involve handling and movements of minimal quantities of radioactive material and will involve methods and processes similar to those used for on-site radiological decontamination and remediation.

Further, since any planned spot remediation will involve the handling of extremely small quantities of radioactive material, the consequences of any postulated accidents will be a small fraction of the consequences of the accidents previously analyzed in the Decommissioning Plan. Therefore, the proposed amendment will not increase the probability or consequences of accidents previously analyzed.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.

Assessment of residual radioactivity in Plum Brook involve sample and survey activities that use techniques and processes that are comparable to those used in on-site assessments.

In addition, radioactivity that will remain in the environmental areas after License Termination will meet the regulatory criteria for unrestricted use specified in 10 CFR 20.1402. 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 radiological criteria to be used in applying for termination of the NRC Licenses will remain the same as originally proposed Enclosure I Page 2 of 3 and are consistent with the criteria of 10 CFR 20 Subpart E for unrestricted use. The results of assessments performed by the Licensee will remain subject to review by the U.S. NRC for adequate implementation of the License Termination criteria.

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.
