ABSTRACT

As part of its redesign of the materials license program, the U.S. Nuclear Regulatory Commission (NRC), Office of Nuclear Material Safety and Safeguards (NMSS) has consolidated and updated numerous decommissioning guidance documents into a three-volume NUREG.

Specifically, the three volumes address the following topics:

(1) “Decommissioning Process for Materials Licensees”;

(2) “Characterization, Survey, and Determination of Radiological Criteria”; and

(3) “Financial Assurance, Recordkeeping, and Timeliness.”

This three-volume NUREG series replaces NUREG-1727 (NMSS Decommissioning Standard Review Plan) and NUREG/BR-0241 (NMSS Handbook for Decommissioning Fuel Cycle and Materials Licensees). NUREG-1757 is intended for use by NRC staff, licensees, and others.

Volume 1 of this NUREG series, entitled “Consolidated Decommissioning Guidance:

Decommissioning Process for Materials Licensees,” takes a risk-informed, performance-based approach to the information needed to support an application for decommissioning a materials license and compliance with the radiological criteria for license termination in 10 CFR Part 20, Subpart E. The approaches to license termination described in this guidance will help to identify the information (subject matter and level of detail) needed to terminate a license by considering the specific circumstances of the wide range of radioactive materials users licensed by NRC.

Licensees should use this guidance in preparing license amendment requests. NRC staff will use this guidance in reviewing these amendment requests.

Volume 1 is intended to be applicable only to the decommissioning of materials facilities licensed under 10 CFR Parts 30, 40, 70, and 72 and to the ancillary surface facilities that support radioactive waste disposal activities licensed under 10 CFR Parts 60, 61, and 63. However, parts of this volume are applicable to reactor licensees, as described in the Foreword to this volume.

PAPERWORK REDUCTION ACT STATEMENT

The information collections contained in this NUREG are covered by the requirements of 10 CFR Parts 19, 20, 30, 33, 34, 35, 36, 39, 40, 51, 60, 61, 63, 70, 72, and 150 which were approved by the Office of Management and Budget, approval numbers 3150–0044, 0014, 0017, 0015, 0007, 0010, 0158, 0130, 0020, 0021, 0127, 0135, 0199, 0009, 0132, and 0032.

1 As of September 2006, NRC is planning to reorganize NMSS and the Office of State and Tribal Programs (STP) to create two new offices: the Office of Federal and State Materials and Environmental Management Programs, which will focus on materials programs; and the new NMSS, which will focus on fuel cycle programs. This reorganization is scheduled to take effect on October 1, 2006. This document contains references to NMSS and STP. These references will be updated in future revisions of this document.

FOREWORD

NRC staff suggests that licensees contact NRC or the appropriate Agreement State authority to assure understanding of what actions should be taken to initiate and complete decommissioning at facilities.

In September 2003, U.S. Nuclear Regulatory Commission (NRC) staff in the Office of Nuclear Material Safety and Safeguards (NMSS)1 consolidated and updated the policies and guidance of its decommissioning program in a three-volume NUREG series, NUREG-1757, “Consolidated Decommissioning Guidance.” This NUREG series provides guidance on: planning and implementing license termination under the NRC’s License Termination Rule (LTR), in the Code of Federal Regulations (CFR), Title 10, Part 20, Subpart E; complying with the radiological criteria for license termination; and complying with the requirements for financial assurance and recordkeeping for decommissioning and timeliness in decommissioning of materials facilities. The staff periodically updates NUREG-1757, so that it reflects current NRC decommissioning policy.

In September 2005, the staff issued, for public comment, draft Supplement 1 to NUREG-1757, which contained proposed updates to the three volumes of NUREG-1757. Draft Supplement 1 included new and revised decommissioning guidance that addresses some of the LTR implementation issues, which were analyzed by the staff in two Commission papers (SECY-03-0069, Results of the LTR Analysis; and SECY-04-0035, Results of the LTR Analysis of the Use of Intentional Mixing of Contaminated Soil). These issues include restricted use and institutional controls, onsite disposal of radioactive materials under 10 CFR 20.2002, selection and justification of exposure scenarios based on reasonably foreseeable future land use (realistic scenarios), intentional mixing of contaminated soil, and removal of material after license termination. The staff also developed new and revised guidance on other issues, including engineered barriers.

The staff received stakeholder comments on Draft Supplement 1 and prepared responses to these comments. The stakeholder comments are located on NRC’s decommissioning Web site, at http://www.nrc.gov/what-we-do/regulatory/decommissioning/reg-guides-comm.html, and the NRC staff responses are located on the same Web site and also in the Agencywide Documents Access and Management System at ML062370521. Supplement 1 has not been finalized as a separate document; instead, updated sections from Supplement 1 have been placed into the appropriate locations in revisions of Volumes 1 and 2 of NUREG-1757. The staff plans to revise Volume 3 of this NUREG series at a later date, and that revision will incorporate the Supplement 1 guidance that is related to Volume 3.

FOREWORD

NUREG–1757, Vol. 1, Rev. 2 xiv

NRC is currently moving toward increasing the use of risk information in its regulation of nuclear materials and nuclear waste management, including the decommissioning of nuclear facilities. NRC’s risk-informed regulatory approach to the decommissioning of nuclear facilities represents a philosophy whereby risk insights are considered together with other factors to better focus the attention and resources of both the licensee and NRC on the more risk-significant aspects of the decommissioning process and on the elements of the facility and the site that will most affect risk to members of the public following decommissioning. This results in a more effective and efficient regulatory process.

The term "risk-informed," as used here, refers to the results and findings that come from risk assessments. A risk assessment is a systematic method for addressing risk. The end results of such assessments (e.g., the calculation of predicted doses from decommissioned sites) may relate directly or indirectly to public health effects. NRC staff has developed this guidance to implement the risk-informed approach and intends that the guidance be implemented in a risk-informed manner.

The primary decommissioning guidance documents used by licensees and NRC staff are NUREG-1757 and NUREG-1700, “Standard Review Plan for Evaluating Nuclear Power Reactor License Termination Plans.” Table 1 below describes the general applicability of these documents. NUREG-1537, “Guidelines for Preparing and Reviewing Applications for the Licensing of Non-Power Reactors,” contains guidance for non-power reactor licensees and NRC staff, which includes a section on decommissioning and license termination for non-power reactors.

2 Licensees regulated under 10 CFR Parts 30, 40, 60, 61, 63, 70, and 72 (for 10 CFR Parts 60, 61, and 63, only the ancillary surface facilities that support radioactive waste disposal activities). Because uranium recovery facilities are not subject to 10 CFR Part 20, Subpart E, refer to NUREG-1620, Rev. 1, Section 5, for decommissioning guidance for uranium recovery facilities that are subject to 10 CFR 40, Appendix A.

The current document, NUREG-1757, Volume 1, Revision 2, was intended to be applicable only to materials licensees. However, parts of this Volume are also applicable to reactor licensees, and the most relevant sections are listed in Table 2.
