Operational perspective on safeguards issues

Description: Today's S S regulatory environment is best characterized as dynamic and turbulent. As a result, S S programs, policies and procedures are rapidly undergoing change, sometimes major, to withstand internal and external scrutiny. Currently the Material Control and Accountability (MC A) DOE Order 5633.3 forms the basis of the MC A programs throughout the DOE complex. Although these requirements can be and often are made more restrictive by the field office and/or the site contractor, this order est… more

Accounting Standards: Treatment of Asset-Backed Securities

Description: Correspondence issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO provided information on whether the greater discretion allowed to banks as opposed to securities broker/dealers under accounting standards and practices may have resulted in less transparency in the value of asset-backed securities held by banks, focusing on: (1) mortgage-backed securities (MBS); (2) the accounting treatment applied to securities (including MBS) held by … more

Management of nuclear materials in an R D environment at the Los Alamos National Laboratory

Description: Los Alamos National Laboratory is a multidisciplinary R D organization and, as such, its nuclear materials inventory is diverse. Accordingly, major inventories of isotopes such as Pu-238, Pu-239, Pu-242, U-235, Th, tritium, and deuterium, and lesser amounts of isotopes of Am, Cm, Np and exotic isotopes such as berkelium must be managed in accordance with Department of Energy Orders and Laboratory policies. Los Alamos also acts as a national resource for many one-of-a-kind materials which are su… more

Development of nuclear materials accounting for international safeguards: The past, the present, the future

Description: Nuclear materials accountancy was introduced as a primary safeguards measure in international safeguards from the inception of the EURATOM safeguards directorate in 1959 and IAEA safeguards in 1961 with the issuance of INFCIRC 26. As measurement technology evolved and safeguarded facilities increased in both number and size, measurement methodology requirements increased as reflected in INFCIRC 66 (Rev 2.) in 1968 and later in INFCIRC 153 in 1972. Early measurements relied heavily on chemical a… more

Electric rate structures for thermal energy storage evaluation

Description: Future electric rate structures are critical to thermal energy storage (TES) technologies that are specifically designed to take advantage of electric energy costs that vary depending on the magnitude, duration, and timing of power demand (e.g., cool storage). In fact, rate structure characteristics may affect the TES system design and operating approach as well as economic feasibility. The objective of this study, conducted by the Pacific Northwest Laboratory for the US Department of Energy, w… more

Comparison of the Savannah River Site billet active well coincidence counter and two Californium Shufflers

Description: A Scrap Californium Shuffler at the Savannah River Site (SRS) was calibrated to assay the U-Al cores of billets (an intermediate step in the SRS reactor fuel fabrication cycle.) The precision of the Scrap Shuffler over several years has been approximately 0.50%. A typical total uncertainty for the assay of a core on the Scrap Shuffler is approximately 0.33% for a twelve minute assay. The precision over several months and a typical total uncertainty for the Billet Active Well (neutron) Coinciden… more

Guidance document on the variance propagation requirements in DOE Order 5633. 3

Description: DOE facilities handling special nuclear material are required to comply with DOE Order 5633.3, which addresses various aspects of nuclear material accounting. In particular, it requires that control limits be calculated for nuclear material inventory differences. These requirements and methods of meeting them are described. The four steps in this process are the creation of a variance propagation model of the nuclear material accounting system, the validation of the model, the application of th… more

Regional and National Estimates of the PotentialEnergy Use, Energy Cost, and CO{sub 2} Emissions Associated with Radon Mitigation by Sub-slab Depressurization

Description: Active sub-slab depressurization (SSD) systems are an effective means of reducing indoor radon concentrations in residential buildings. However, energy is required to operate the system fan and to heat or cool the resulting increased building ventilation. We present regional and national estimates of the energy requirements, operating expenses, and CO{sub 2} emissions associated with using SSD systems at saturation (i.e., in all U.S. homes with radon concentrations above the EPA remediation gui… more

Novel Regenerated Solvent Extraction Processes for the Recovery of Carboxylic Acids or Ammonia from Aqueous Solutions Part II. Recovery of Ammonia from Sour Waters

Description: Two novel regenerated solvent extraction processes are examined. The first process has the potential to reduce the energy costs inherent in the recovery of low-volatility carboxylic acids from dilute aqueous solutions. The second process has the potential for reducing the energy costs required for separate recovery of ammonia and acid gases (e.g. CO{sub 2} and H{sub 2}S) from industrial sour waters. The recovery of carboxylic acids from dilute aqueous solution can be achieved by extraction with… more

An application of neural networks to process and materials control

Description: Process control consists of two basic elements: a model of the process and knowledge of the desired control algorithm. In some cases the level of the control algorithm is merely supervisory, as in an alarm-reporting or anomaly-detection system. If the model of the process is known, then a set of equations may often be solved explicitly to provide the control algorithm. Otherwise, the model has to be discovered through empirical studies. Neural networks have properties that make them useful in t… more

Departmentwide audit of the visibility over the status of nuclear materials

Description: Over the last 45 years, DOE has acquired and produced significant quantities of nuclear material. Much of it is in warheads in the custody of the Department of Defense. The rest is at DOE laboratories, production activities, and assembly plants. Uranium, plutonium, and tritium constitute the bulk of DOE's nuclear materials inventory. Nuclear materials managers should know the status of material and how it is being used so that stocks can be acquired, maintained, and disposed of in a safe, econo… more

Experimental validation of pulsed column inventory estimators

Description: Near-real-time accounting (NRTA) for reprocessing plants relies on the timely measurement of all transfers through the process area and all inventory in the process. It is difficult to measure the inventory of the solvent contractors; therefore, estimation techniques are considered. We have used experimental data obtained at the TEKO facility in Karlsruhe and have applied computer codes developed at Clemson University to analyze this data. For uranium extraction, the computer predictions agree … more

The impact of rising energy prices on household energy consumption and expenditure patterns: The Persian Gulf crisis as a case example

Description: The Iraqi invasion of Kuwait and the subsequent war between Iraq and an international alliance led by the United States triggered immediate increases in world oil prices. Increases in world petroleum prices and in US petroleum imports resulted in higher petroleum prices for US customers. In this report, the effects of the Persian Gulf War and its aftermath are used to demonstrate the potential impacts of petroleum price changes on majority, black, and Hispanic households, as well as on poor and… more
