  • BackgroundAs a national registry, the NSTS will contain information on radioactive sources possessed by NRC and Agreement State licensees and facilities established by the U.S. Department of Energy (DOE). Also, because the NSTS is designed as a transaction-based system, it will not provide real-time tracking. Rather, licensees will use this Web-based resource to report the manufacture, transfer, receipt, disassembly, and disposal of nationally tracked sources. Basic information tobecollected will include the manufacturer, model number, serial number, radioactive material, activity, and manufacture date of each source, as well as information on the facilities involved inany transaction.Within the scope of the NSTS, the sources of interest are a subset of sealed sources, known as nationally tracked sources. A sealed source consists of radioactive material that is sealed inacapsule, or is closely bonded to a non-radioactive substrate designed to prevent leakage orescape of the radioactive material. In either case, a sealed source is effectively a solid form ofradioactive material, which is subject to regulatory control.Nationally tracked sources represent the subset of sealed sources that contain quantities ofradioactive material that are equal to or greater than the Category2 Nationally Tracked Source Thresholds set forth in AppendixE toTitle10, Part20, of the Code of Federal Regulations (10CFRPart20), Standards for Protection Against Radiation. In other words, nationally tracked sources may be classified as either Category1 or Category2 sources, depending on theactivity of the given radioactive material.Nationally tracked sources are possessed by all types of licensees (but primarily byproduct material licensees), and are used for a variety of purposes in the oil and gas, electrical power, construction, medical, and food industries. They are also used in a variety of military applications, aswellas technology research and development. Category1 sources are typically used inpractices such as radiation therapy (brachytherapy), and in devices such as radio-thermal generators and irradiators. Bycontrast, Category2 sources are typically used in blood irradiators, industrial gamma radiography, and some well-logging applications.

  • Final NRC RuleNSTSNRC Rule on the National Source Tracking SystemIn November 2006, the U.S. Nuclear Regulatory Commission (NRC) issued the Final Rule incorporating the National Source Tracking System (NSTS) into the agencys regulations, andimplementing provisions of the Energy Policy Act of 2005 . As specified in that rule, theNRCs NSTS regulations are set forth in Title10, Section20.2207, of the Code of Federal Regulations (10 CFR 20.2207), Reports of Transactions Involving Nationally Tracked Sources. (Each Agreement State will implement equivalent requirements for its licensees.) Underthose regulations, all licensees musttake thefollowing actions:Report the licensees initial inventories of Category 1 and Category 2 sources, asdefinedinAppendixE to10CFRPart20, Standards for Protection Against Radiation, byJanuary31, 2009. Begin reporting all related transactions (manufacture, transfer, receipt, disassembly, ordisposal of sources of interest) totheNSTS by January 31, 2009. Verify (on an annual basis) the records in the NSTS, and reconcile that information withthelicensees actual inventory. Licensees have several options for reporting transaction information to the NSTS:Secure Web-based access to the database Submittal of files in computer-readable format Submittal of the paper-based National Source Tracking Transaction Report (NRCForm748) bymailorfax Telephone reporting to the NSTS Help Desk.

  • Update - NCProgress, not perfectionIn May only 37% of NC licensees had inventories in NSTSToday 85% have reported inventoriesMany inaccuracies in inventoriesErrors being corrected individually

  • Update - CredentialingProblems continue, but improvementProblems being resolved one-on-one by NSTS Help Desk and/or NRCNRC encourages everyone to establish on-line access to NSTS!

  • Update - AccuracyPoorReporting devices, not sourcesDuplication of sourcesMultiple sources being reported as oneSources below CAT 2 being reportedData Integrity Team (NRC)10 member team4 weeks oldMay contact in next 30 days

  • Update - ReconciliationRequired by 10 CFR 20.2207January 2010Fundamental procedurePossible mock reconciliation exerciseI have all inventories with me today

  • Update NRC Websitehttp://www.nrc.gov/security/byproduct/nsts.htmlNew lookBlog and subscription
