A consequence index approach to identifying radiological sabotage targets

Description: One of the threats of concern to facilities using significant quantities of radioactive material is radiological sabotage. Both the Department of Energy (DOE) and the US Nuclear Regulatory Commission have issued guidance to facilities for radiological sabotage protection. At those facilities where the inventories of radioactive materials change frequently, there is an operational need for a technically defensible method of determining whether or not the inventory of radioactive material at a gi… more

ENFORM: an ENergy inFORMation system

Description: The ENFORM system of computer codes can be used to calculate the amount of fuel material in the nuclear fuel cycle as a function of time. The material amounts are determined by an input schedule of installed electric energy generation capacity. In addition to the amount of uranium and plutonium in the fuel cycle, the system also accounts for 175 radionuclides. The effect of the fuel cycle on the environment can be calculated for the release of radionuclides and chemicals. The released radionucl… more

Analytical chemistry needs for nuclear safeguards in nuclear fuel reprocessing

Description: A fuel reprocessing plant designed to process 1500 tons of light water reactor fuel per year will recover 15 tons of Pu during that time, or approximately 40 to 50 kg of Pu per day. Conventional nuclear safeguards accountability has relied on batch accounting at the head and tail ends of the reprocessing plant with semi-annual plant cleanout to determine in-process holdup. An alternative proposed safeguards system relies on dynamic material accounting whereby in-line NDA and conventional analyt… more

Uranium daughter growth must not be neglected when adjusting plutonium materials for assay and isotopic contents

Description: Relationships are provided to compute the decreasing plutonium content and changing isotopic distribution of plutonium materials for the radioactive decay of /sup 238/Pu, /sup 239/Pu, /sup 240/Pu and /sup 242/Pu to long-lived uranium daughters and of /sup 241/Pu to /sup 241/Am. This computation is important to the use of plutonium reference materials to calibrate destructive and nondestructive methods for assay and isotopic measurements, as well as to accountability inventory calculations.

Overview of the SECOM II communications system

Description: The conversion of the SECOM system to the SECOM II configuration has been completed and all communications between the central control station and vehicles carrying nuclear weapons and special nuclear materials are being handled by the SECOM II system. A summary of the system characteristics and the improvements achieved over the all-voice system is shown. Through the combined efforts of ALO and Sandia personnel, the transition from SECOM to SECOM II was achieved with a minimum disruption to th… more

Structure for the decomposition of safeguards responsibilities

Description: A major mission of safeguards is to protect against the use of nuclear materials by adversaries to harm society. A hierarchical structure of safeguards responsibilities and activities to assist in this mission is defined. The structure begins with the definition of international or multi-national safeguards and continues through domestic, regional, and facility safeguards. The facility safeguards is decomposed into physical protection and material control responsibilities. In addition, in-trans… more

Transaction oriented minicomputer allows flexible design of the controlled materials information system

Description: The design of business data processing applications utilizing minicomputers requires special considerations throughout the development of the systems project. Minicomputer features, capabilities, and limitations must be closely examined prior to the implementation of the design phase. The design requirements of an inventory control minicomputer system currently being installed by the Data Processing Services Department of Lawrence Livermore Laboratory are presented.

Safeguards technology: present posture and future impact

Description: With widespread and growing concern over the issues of nuclear safeguards, international nuclear trade and nuclear weapons proliferation, the full development of the world's nuclear energy potential could well depend on how effectively the strategic nuclear materials that fuel nuclear power are controlled and safeguarded. The broad U.S. program in nuclear safeguards and security is directed toward a balanced safeguards system incorporating the two major components of physical security and mater… more

Design information questionnaire for a model mixed oxide fuel fabrication facility. [IAEA form]

Description: The model fuel plant is based on the proposed Westinghouse Anderson, S.C., plant and is typical of plants that will be constructed and operated in 1980 to 1990. A number of plant systems and procedures are uncertain, and in these cases judgment was used in describing relevant parameters in order to provide a complete model on which to design an inspection plan. The model plant does not, therefore, strictly represent any planned facility nor does it strictly represent the ideas of Westinghouse o… more

Plutonium calorimetry and SNM holdup measurements. Progress report for the period March 1976--August 1976

Description: The calorimetric instrumentation developed at Argonne National Laboratory (ANL) for making nondestructive measurements of the plutonium content of fuel rods is discussed. Measurements with these instruments are relatively fast (i.e., 15 to 20 minutes) when compared to the several hours usually required with more conventional calorimeters and for this reason are called ''fast-response.'' Most of the discussion concerns the One-Meter and the Four-Meter Fuel-Rod Calorimeters an… more
