Understanding and accepting fusion as an alternative energy source

Description: Fusion, the process that powers our sun, has long promised to be a virtually inexhaustible source of energy for mankind. No other alternative energy source holds such bright promise, and none has ever presentd such formidable scientific and engineering challenges. Serious research efforts have continued for over 30 years in an attempt to harness and control fusion here on earth. Scientists have made considerable progress in the last decade toward achieving the conditions required for fusion pow… more

Actinide removal from aqueous solution with activated magnetite

Description: An actinide aqueous waste treatment process using activated magnetite has been developed at Rocky Flats. The use and effectiveness of various magnetites in lowering actinide concentrations in aqueous solution are described. Experiments indicate that magnetite particle size and pretreatment (activation of the magnetite surface with hydroxyl ions greatly influence the effective use of magnetite as an actinide adsorbent. With respect to actinide removal, Ba(OH)/sub 2/-activated magnetite was more … more

VFI: VME/FASTBUS Interface routines

Description: This documents describes the VME/FASTBUS Interface routines (VFI). These routines where designed to enable programs written in PILS running on a MVME 101 under Valet-plus to control a VME/FASTBUS Interface. The routines fall into two general types, control and transaction. The control routines, such as vmec-reset, work directly with the interface's registers. These routines set up and monitor operations between VME and FASTBUS. The transaction routines, such as vfi-write-dat, use the control ro… more

High resolution seismic attenuation tomography at Medicine Lake Volcano, California

Description: Medicine Lake Volcano, a broad shield volcano about 50km east of Mount Shasta in northern California, produced rhylotic eruptions as recently as 400 years ago. Because of this recent activity it is of considerable interest to producers of geothermal energy. In a joint project sponsored by the Geothermal Research Program of the USGS and the Division of Geothermal and Hydropower Division of the US-DOE, the USGS and LLNL conducted an active seismic experiment designed to explore the area beneath a… more

Development of fiber optics sensors for temperature measurement and chemical analysis in geothermal wells

Description: In this paper the results of research on high temperature optical fiber sensors will be presented. We have shown that these sensors (optrodes) can be made to work in very high temperature water for long periods and that it is possible to measure pH using fluorescent inorganic ions doped into solid matrices. A high temperature pH optrode can be made using these techniques, however, more research is needed into the chemistry of the carrier matrices and fluorescent dopants.

Smoke clearing by high energy laser beams

Description: We describe the clearing phenomenon that occurs when a continuous wave (CW) high energy laser beam, incident upon a cloud of hygroscopic droplets, vaporizes these droplets. We consider the case when the incident wavelength is greater than the average droplet radius. Williams' model is used to describe the vaporization of a single droplet. The propagation of the laser beam is described by the radiative transfer equation in a slab geometry. The radiative transfer equation is solved using the meth… more

Tactical Vulnerability Assessment Training Program

Description: The Department of Energy sponsors a 9-day training program for individual who are responsible for evaluating and planning safeguards systems and for preparing DOE Master and Security Agreements (MSSAs). These agreements between DOE headquarters and operations offices establish required levels of protection. The curriculum includes: (1) the nature of potential insider and outsider threats involving theft or diversion of special nuclear material, (2) use of computerized tools for evaluating the e… more

Seismic margin reviews of nuclear power plants: Identification of important functions and systems

Description: The purpose of this paper is to present the basis and method used for the development of the systems screening portion of the seismic margin review methodology. The results from the review of seven utility-sponsored seismic PRA's and one Seismic Safety Margins Research Program Study have been used to develop some insights regarding the importance of various systems and functions to seismic margins.

The Department of Energy's collection procedures for defaulted Geothermal Loan Guaranties

Description: Delays of up to 2 years were experienced in liquidating $9.5 million in collateral on three defaulted loans. Although the Department had paid lenders $32.5 million on these defaulted loans, it had not notified the US Attorney General. Also, it had not prepared final liquidation plans as provided by regulations. As a result of these delays, the collective value of the collateral has decreased by about $2.7 million, and the Department has incurred over $690,000 in lease maintenance and administra… more

Unorthodox lattice fermion derivatives and their shortcomings

Description: We discuss the DWY (Lagrangian), Quinn-Weinstein, and Rebbi proposals for incorporating fermions into lattice gauge theory and analyze them in the context of weak coupling perturbation theory. We find that none of these proposals leads to a completely satisfactory lattice transcription of fully-interacting gauge theory.

Validating safeguards effectiveness given inherently limited test data

Description: A key issue in designing and evaluating nuclear safeguards systems is how to validate safeguards effectiveness against a spectrum of potential threats. Safeguards effectiveness is measured by a performance indicator such as the probability of defeating an adversary attempting a malevolent act. Effectiveness validation means a testing program that provides sufficient evidence that the performance indicator is at an acceptable level. Traditional statistical techniques are useful in designing a te… more

D-Zero Colling Loops

Description: This report provides the necessary sizing for the LN{sub 2} cooling coils in the D-Zero cryostats. Natural convection from finned tubes will be the means of cooling the cryostats and their contents until such time as liquid can be made by condensing. Each cryostat will contain three separate cooling runs. Two runs will be cooldown and the other steady state. These runs will be placed in each cryostat as shown in figure 3, 4a and 4b. By assuming a 100 K tube wall temperature, tube diameter (3/4-… more

Central Calorimeter Support Cradle Jack Failure Analysis

Description: The Central Calorimeter and its support cradle are to be supported by either hydraulic or mechanical jacks. If hydraulics are used, each support will use two hydraulically coupled jacks with two out of the four supports hydraulically coupled giving the effect of a three point support system. If mechanical jacks are used, all four points are used for support. Figure 2 shows two examples of jack placement on a 3.5 inch support plate. These two support scenarios lead to five jack failure cases to … more

Application of state-multipole Heisenberg equations to Raman excitation dynamics

Description: Description of detailed temporal excitation dyanmics for coherent excitation, such as is produced by idealized laser radiation, contrasts with evaluation of rate coefficients by means of generalized Golden Rule procedures; it requires an appropriate time-dependent Schroedinger equation. When the atom undergoing excitation is also affected by incoherent processes, such as collisions, this equation no longer suffices. The Heisenberg equations, or equivalent density-matrix equations, permit treatm… more

Radiation effects and annealing kinetics in crystalline silicates, phosphates and complex Nb-Ta-Ti oxides. FInal Report

Description: Interaction of heavy particles (alpha-recoil nuclei, fission fragments, implanted ions) with ceramics is complex because they have a wide range of structure types, complex compositions and chemical bonding is variable. Radiation damage can produce diverse results, but most commonly, crystalline periodic materials become either polycrystalline or aperiodic (metamict state). We studied the transition from crystalline to aperiodic state in natural materials that have been damaged by alpha recoil n… more
