E9–13715 Filed 6–10–09; 8:45 am] BILLING CODE 7590–01–P NUCLEAR REGULATORY COMMISSION [NRC–2009–0231; EA–09–131] In the Matter of General Motors Corporation, Detroit, MI; Demand for Information jlentini on PROD1PC65 with NOTICES I The Nuclear Regulatory Commission (NRC or Commission) is issuing this Demand for Information because it is our understanding that General Motors Corporation (GM) possesses radioactive material in the form of tritium in exit signs. Because GM possesses radioactive material in this form, it holds what is referred to as a ‘‘general license’’ to VerDate Nov<24>2008 16:37 Jun 10, 2009 Jkt 217001 possess such material. In this case, GM’s general license has been issued by the NRC pursuant to section 31.5 in Part 10 of the Code of Federal Regulations (10 CFR 31.5). This general license authorizes GM, the licensee, to receive, possess, use, or transfer, in accordance with the provisions of paragraphs (b), (c) and (d) of 10 CFR 31.5, radioactive material contained in devices designed and manufactured for the purpose of producing light. II On December 7, 2006, NRC issued Regulatory Issue Summary (RIS) 2006– 25, ‘‘Requirements for the Distribution and Possession of Tritium Exit Signs and the Requirements in 10 CFR 31.5 and 32.51a.’’ This RIS was issued in part to remind general licensees of the requirements in 10 CFR 31.5 regarding transfer and disposal of tritium exit signs. It was NRC’s intent that issuance of this RIS would minimize the chances of improper disposal of tritium exit signs. Despite the publication of the RIS in 2006, NRC has reason to believe that certain general licensees may lack awareness of their responsibility to account for and properly dispose of tritium exit signs. Therefore, the NRC needs further information to determine whether we can have reasonable assurance that general licensees are complying with NRC regulations applying to the possession, transfer, and disposal of tritium exit signs. III Accordingly, pursuant to sections 161c, 161o, 182 and 186 of the Atomic Energy Act of 1954, as amended, and the Commission’s regulations in 10 CFR 2.204 and 10 CFR 31.5, the NRC seeks information in order to determine whether additional regulatory action should be taken to ensure compliance with NRC requirements. Within 60 days of the date of this Demand for Information, GM must submit a written answer to the Director, Office of Federal and State Materials and Environmental Management Programs, U.S. Nuclear Regulatory Commission, Washington, DC 20555–0001. GM’s answer must be submitted under oath or affirmation, and it must provide the following information: A. Explain how GM ensures compliance with the NRC requirements applying to the possession, transfer, and disposal of tritium exit signs GM has acquired. Identify and provide contact information for the individual GM has appointed who is responsible for ensuring day to day compliance with these requirements; PO 00000 Frm 00065 Fmt 4703 Sfmt 4703 27831 B. State the number of tritium exit signs GM currently possesses and the number of signs that, according to GM’s records, should be in GM’s possession. C. Explain the reasons for any discrepancy between the number of tritium exit signs GM currently possesses and the number of signs that should be in GM’s possession. D. Describe any actions GM has taken or plans to take, to locate tritium exit signs that should be, but are not, in GM’s possession. E. Describe any actions GM has taken or plans to take, to prevent future losses of tritium exit signs. After reviewing GM’s response, the NRC will determine whether further action is necessary to ensure compliance with regulatory requirements. The Director, Office of Federal and State Materials and Environmental Management Programs, may, in writing, relax or rescind any of the above conditions upon demonstration by the Licensee of good cause, such as a particularly large number of signs spread over multiple locations. If GM believes GM cannot report the results within the 60-day deadline, GM may forward a request to extend the deadline. Extensions will be granted if GM can reasonably demonstrate an inability to meet the deadline. Additionally, any other requirement can be relaxed or rescinded, as long as GM can reasonably demonstrate why that requirement should be relaxed or rescinded. Such requests may be emailed to MSEA@nrc.gov or faxed to Angela McIntosh at (301) 415–5955. Questions about this Demand for Information may be referred to Tritium Exit Sign Inventory Support at (301) 415–3340. Send responses to: Director, Office of Federal and State Materials and Environmental Management Programs, Attention: Angela R.

The research approach employed to establish appropriate diversity strategies involves investigation of available documentation on D3 methods and experience from nuclear power and nonnuclear industries, capture of expert knowledge and lessons learned, determination of commonalities in diversity approaches, and assessment of the nature of common-cause failures (CCFs) and compensating diversity attributes. Succinctly, the purpose of the research described in this report was to answer the question, ‘‘If diversity is needed in a safety system to mitigate the consequences of potential CCFs, how much diversity is enough?’’ The grouping of diversity criteria combinations establishes baseline diversity usage and facilitates a systematic organization of strategic approaches for coping with CCF vulnerabilities. These baseline sets of diversity criteria constitute appropriate CCF mitigating strategies for digital safety systems. The strategies represent guidance on acceptable diversity usage and can be applied directly to ensure that CCF vulnerabilities identified VerDate Nov<24>2008 16:37 Jun 10, 2009 Jkt 217001 through a D3 assessment have been adequately resolved.

SUPPLEMENTARY INFORMATION:

I. Introduction

    The U.S. Nuclear Regulatory Commission (NRC) is issuing for public 
comment a draft contractor report in the agency's ``NUREG/CR'' series. 
This series was developed to describe and make available to the public 
information such as the results of research conducted on behalf of the 
NRC regarding specific approaches for implementing safety systems in 
accordance with NRC regulations.
    The draft contractor report (NUREG/CR), entitled, ``Diversity 
Strategies for Nuclear Power Plant Instrumentation and Control 
Systems,'' is temporarily identified as ``Diversity NUREG/CR'', which 
should be mentioned in all related correspondence.
    This report presents the technical basis for establishing 
acceptable mitigating strategies that resolve diversity and defense-in-
depth (D3) assessment findings and conform to NRC requirements. The 
research approach employed to establish appropriate diversity 
strategies involves investigation of available documentation on D3 
methods and experience from nuclear power and nonnuclear industries, 
capture of expert knowledge and lessons learned, determination of 
commonalities in diversity approaches, and assessment of the nature of 
common-cause failures (CCFs) and compensating diversity attributes. 
Succinctly, the purpose of the research described in this report was to 
answer the question, ``If diversity is needed in a safety system to 
mitigate the consequences of potential CCFs, how much diversity is 
enough?''
    The grouping of diversity criteria combinations establishes 
baseline diversity usage and facilitates a systematic organization of 
strategic approaches for coping with CCF vulnerabilities. These 
baseline sets of diversity criteria constitute appropriate CCF 
mitigating strategies for digital safety systems. The strategies 
represent guidance on acceptable diversity usage and can be applied 
directly to ensure that CCF vulnerabilities identified through a D3 
assessment have been adequately resolved. Additionally, a framework has 
been generated for capturing practices regarding diversity usage. A 
metric has been developed for the systematic assessment of the 
comparative effect of proposed diversity strategies on the basis of 
these practices (see Appendix A).
