WASHINGTON, DC 20555 September 7, 2007 NRC REGULATORY ISSUE SUMMARY 2007-18 DATA FOR UPDATING THE INTERIM
INVENTORY OF RADIOACTIVE SOURCES
ADDRESSEES
All U.S. Nuclear Regulatory Commission (NRC) Part 40, Part 50, Part 70, Part 72, and Part 76 licensees and certificate holders who are authorized to possess sources of radioactive material at the Category 3.5" (as defined below) activity or higher.
INTENT
NRC is issuing this regulatory issue summary (RIS) to inform addressees of a forthcoming survey of data for input into the interim inventory of radioactive sources. The submission of this information will be voluntary. No specific action or response to this RIS is required.
BACKGROUND
The events of September 11, 2001, heightened the Nations concerns about the possible use of radioactive material for malevolent acts. In June 2002, the Secretary of Energy and the NRC
Chairman met to address these concerns, and agreed to convene an Interagency Working Group on Radiological Dispersal Devices (hereafter, WG). In May 2003, the WG issued its report. The report is available on the Internet at: https://homer.ornl.gov/nrc/nrc-doerddrpt.pdf.
The WG report included a list of radionuclides and thresholds above which tracking of the sources was recommended. A similar study, undertaken by the International Atomic Energy Agency (IAEA), created a list of radionuclides and thresholds much the same as the Department of Energy (DOE)/NRC list. In July 2003, the IAEA published their source categorization scheme. That scheme is incorporated in the IAEA Code of Conduct for the Safety and Security of Radioactive Sources (January 2004). The Code of Conduct is available at: https://homer.ornl.gov/nrc/codeofconductenglish.pdf. In August 2005, the IAEA re-issued their scheme as the safety standard, RS-G-1.9, Categorization of Radioactive Sources.
NRC has adopted the IAEA source categorization scheme and established the Category 2 threshold for certain radionuclides as the level for implementation of several new actions (see Enclosure 1 for the list of nuclides and their Category 2 thresholds) in support of international cooperation on source tracking. On December 28, 2005, new import/export regulations concerning radioactive sources at or above the IAEA Category 2 thresholds became effective.
On November 8, 2006, NRC published the final rule for a new National Source Tracking System (NSTS) to track radioactive sources at or above the IAEA Category 2 thresholds.
The NSTS is expected to be implemented in the summer of 2008 with the exact date published in the Federal Register at least three months in advance. In 2005, NRC and Agreement States issued Orders or other legally binding requirements that established new security measures for licensees authorized to possess Category 2, or greater, quantities of material.
SUMMARY OF ISSUE
Until the NSTS is implemented, the Commission directed that NRC and the Agreement States maintain an interim inventory of sources at, or above, the IAEA Category 2 threshold. This inventory has been updated annually by querying all licensees authorized to possess these sources. The first round of requests was issued between November 2003, and October 2004, and the response provided a snapshot of sources possessed at the time of the query response. The first round included aggregated amounts (individual sources below the threshold, but which summed to a total above a threshold) and asked about source import/export and disposition plans. The next two rounds, performed in Fiscal Year (FY) 2005 and FY 2006, were similar, but did not include aggregation, nor did it ask about plans for import/export or source disposition.
On June 9, 2006, the Commission directed the commencement of an information collection on sources at or above an activity that is much lower than the previous thresholds (SECY-06-
0094). Specifically, NRC and the Agreement States were directed to collect data on sources at, or above, a threshold identified as Category 3.5. The IAEA defines Category 3 as one-tenth of Category 2. The IAEA defines Category 4 as one-hundredth of Category 3. The Commission has defined Category 3.5 as one-tenth of Category 3, or one-hundredth of Category 2.
As a result, NRC and the Agreement States have updated the inventory with lists of licensees authorized to possess radionuclides on the IAEA list in sources or quantities that are at or above the new Category 3.5 threshold. All licensees on the updated list will be contacted by letter or electronic mail to request information on sources at or above the Category 3.5 threshold. If licensees previously acknowledged possessing sources, they will be provided their previous data and asked to update it. If the licensees do not possess any sources at or above the Category 3.5 threshold, they will be asked to state this in their responses. As before, the responses will be for the instant in time, snapshot, of when the licensees respond. The data will be available to NRC and the Agreement States and some data may be shared with other Federal agencies, including DOE and the Department of Homeland Security, to assist with their roles in source security.
The reasons for maintaining the inventory are:
C
To maintain an inventory of the sources at or above the Category 2 threshold and feed these data to the NSTS in 2008;
C
To maintain or establish contact with the licensees that will participate in the system;
C
To provide specific information on the number, types, general uses, and geographic locations of sources in use;
C
To plan for the possible expansion of the NSTS, to include Category 3 sources;
and C
To evaluate the effect of limiting generally licensed devices to a maximum activity of Category 3.5. SURVEY INFORMATION -
VOLUNTARY RESPONSE
REQUESTED
All addressees are requested to voluntarily submit a response to the survey when they receive it. Responses should be submitted within 30 days of the receipt of the survey. As discussed below, each licensee will be contacted separately and instructed on how to participate in the survey. The survey will be available on an NRC independent contractors secure website until Fall 2008 for viewing, downloading, and responding.
NRC-licensed addressees that choose to participate in the survey may do so by using the Internet to respond directly or to download the survey form to complete and mail or fax their response to the address or phone numbers provided in the instructions.
The method of Agreement State licensed addressees participation in the survey will be determined by each Agreement State. Some Agreement States have chosen to allow the NRC
contractor to contact their licensees and participation will be similar to the participation by NRC-
licensed addressees as discussed above. Some Agreement States have chosen to contact their own licensees and will obtain the survey data from the licensees and provide it to NRC.
Enclosure 2 provides information on the new Category 3.5 threshold values for the radionuclides of interest and the types of information being requested. As before, Oak Ridge National Laboratory will collect the inventory information for NRC. Username and passwords to access the secure website and instructions on how to provide the data will be mailed separately. If you provided any data in a previous response, those data are displayed when you log in to the Internet site, using the provided user name and password. You are requested to follow the instructions and update any prior data. If you do not possess any sources at or above the applicable threshold, please follow the instructions to positively indicate this. Data collection is through a secure Internet web site.
Although the Category 3.5 threshold could include devices that are usually generally licensed under current regulations, you do not need to include any of these devices in this survey unless they are included on your specific license. NRC will obtain data on devices being operated under a general license directly from the Agreement States or the General License Tracking System.
BACKFIT DISCUSSION
This RIS requires no action or written response. Any action on the part of addressees to respond to the survey in accordance with the guidance contained in this RIS is strictly voluntary and, therefore, is not a backfit under 10 CFR 50.109, 70.76, and 76.76. Consequently, the staff did not perform a backfit analysis.
FEDERAL REGISTER NOTIFICATION
A notice of opportunity for public comment on this RIS was not published in the Federal Register because the RIS is informational and involves the voluntary submission of information on the part of addressees.

2 The IAEA Code of Conduct uses Becquerel-based values. The Category 4 values are defined as 1/100th of the Category 3 value. The Commission has determined it needs data to a level in between Category 3 and 4. It has chosen Category 3.5 to be one-tenth of Category 3 or 10 times Category 4. The Becquerel-based values in Table 2 are the IAEA Category 3 values divided by 10 and are the standards for the FY 2007 inventory.
3 In the Code of Conduct, when the IAEA converted the Becquerel values to Curie values, they were rounded to one significant digit after conversion. This is the proper method to convert. However, for simplicity in determining whether a given quantity exceeds the applicable threshold standard, the Curie values listed here are the exact values determined by using the formulas above, rounded to three significant digits, and not less than one- thousand of a Curie (or to the nearest milliCurie).
