Preliminary concepts for materials measurement and accounting in critical facilities

Description: Preliminary concepts are presented for improved materials measurement and accounting in large critical facilities. These concepts will be developed as part of a study that will emphasize international safeguarding of critical facilities. The major safeguards problem is the timely verification of in-reactor inventory during periods of reactor operation. This will require a combination of measurement, statistical sampling, and data analysis techniques. Promising techniques include integral measur… more

Description: The principles and techniques of absorption edge densitometry in the energy-dispersive mode are summarized as they apply to the nondestructive assay of special nuclear materials. Five existing field instruments, designed for special nuclear materials accounting measurements, are described. Results of the testing of these instruments as well as recent laboratory results are used to define the capabilities of the technique for special nuclear materials accounting. Possibilities for future applica… more

Final report to the President on oil supply shortages during 1979

Description: Stockpile levels at the beginning of 1979, imports during the first half of the year, and inventory management were primarily responsible for the oil supply shortage in the spring and summer of 1979. There was a 3.1% reduction in oil supply in May to July of 1979 relative to the same period in 1978, and a 0.2% reduction relative to 1977. The reduction in available oil between 1979 and previous years was even greater than the reduction in supply. Domestic production of crude oil declined between… more

Mass-spectrometric measurements for nuclear safeguards

Description: The need of an on-site inspection device to provide isotopic ratio measurements led to the development of a quadrupole mass spectrometer mounted in a van. This mobile laboratory has the ability, through the use of the resin bead technique, to acquire, prepare, and analyze samples of interest to nuclear safeguards. Precision of the measurements is about 1 to 2%.

Experimental /sup 233/U nondestructive assay with a random driver

Description: Nondestructive assay (NDA) of /sup 233/U in quantities up to 15 grams containing 7 ppM /sup 232/U age 2 years was investigated with a random driver. A passive singles counting technique showed a reproducibility within 0.2% at the 95% confidence level. This technique would be applicable throughout a process in which all of the /sup 233/U had the same /sup 232/U content at the same age. Where the /sup 232/U content varies, determination of /sup 233/U fissile content would require active NDA. Acti… more

Applications of Kalman Filtering to nuclear material control. [Kalman filtering and linear smoothing for detecting nuclear material losses]

Description: The feasibility of using modern state estimation techniques (specifically Kalman Filtering and Linear Smoothing) to detect losses of material from material balance areas is evaluated. It is shown that state estimation techniques are not only feasible but in most situations are superior to existing methods of analysis. The various techniques compared include Kalman Filtering, linear smoothing, standard control charts, and average cumulative summation (CUSUM) charts. Analysis results indicated th… more

Analysis of the role of an interfacility SNM accounting system

Description: Lawrence Livermore National Laboratory (LLNL) undertook the task of analyzing the actual and potential value of an interfacility NRC material accounting system in deterring and detecting both material diversion and facility material accounting data falsification. The most important conclusion is that only relatively minor changes are needed to upgrade the current NRC interfacility reporting system. The emphasis of the task was on evaluating the usefulness of an NRC-monitored material accounting… more

Automated calibrations and dynamic corrections for differential pressure transmitters

Description: A large reprocessing plant is a complex operation with dynamic inventories being required to provide for timely detection of attempted diversion of nuclear materials. The real-time, on-line process measurement capability controls the effectiveness of the dynamic techniques. An economical method to eliminate bias and significantly improve process differential pressure transmitter measurements is evaluated. Errors up to 1.0% have been reduced to less than 0.1%

Review of effectiveness-evaluation methodologies for safeguards and security systems

Description: We discuss the factors that influence the effectiveness of safeguards and security measures and the characteristics required of effectiveness evaluation methodologies. Within this context and from a utility standpoint, we review those effectiveness evaluation methodologies that have been developed. Our principal recommendation concerns the application and concomitant validation of existing methodologies. This recommendation derives from our conclusion that there has been a gross imbalance betwe… more

Extrinsic and intrinsic complexities of the Los Alamos Plutonium Processing Facility

Description: Analysis of the data obtained in one year of plutonium accounting at Los Alamos reveals significant complexity. Much of this complexity arises from the complexity of the processes themselves. Additional complexity is induced by errors in the data entry process. It is important to note that there is no evidence that this complexity is adversely affecting the accounting in the plant. We have been analyzing transaction data from fiscal year 1983 processing. This study involved 62,595 transactions.… more
