A Virtual Reality Framework to Optimize Design, Operation and Refueling of GEN-IV Reactors.

Description: many GEN-IV candidate designs are currently under investigation. Technical issues related to material, safety and economics are being addressed at research laboratories, industry and in academia. After safety, economic feasibility is likely to be the most important crterion in the success of GEN-IV design(s). Lessons learned from the designers and operators of GEN-II (and GEN-III) reactors must play a vital role in achieving both safety and economic feasibility goals.

Progress in converting {sup 99}Mo production from high- to low-enriched uranium--1999.

Description: Over this past year, extraordinary progress has been made in executing our charter to assist in converting Mo-99 production worldwide from HEU to LEU. Building on the successful development of the experimental LEU-foil target, we have designed a new, economical irradiation target. We have also successfully demonstrated, in collaboration with BATAN in Indonesia, that LEU can be substituted for HEU in the Cintichem target without loss of product yield or purity; in fact, conversion may make econo… more

Analyses in Support of Z-IFE LLNL Progress Report for FY-05

Description: The FY04 LLNL study of Z-IFE [1] proposed and evaluated a design that deviated from SNL's previous baseline design. The FY04 study included analyses of shock mitigation, stress in the first wall, neutronics and systems studies. In FY05, the subject of this report, we build on our work and the theme of last year. Our emphasis continues to be on alternatives that hold promise of considerable improvements in design and economics compared to the base-line design. Our key results are summarized here. more

A DECONTAMINATION PROCESS FOR METAL SCRAPS FROM THE DECOMMISSIONING OF TRR

Description: A decontamination facility including surface condition categorizing, blasting, chemical/electrochemical cleaning, very low radioactivity measuring, and melting, is being established at INER. The facility will go into operation by the end of 2004. The main purpose is to clean the dismantled metal wastes from the decommissioning of Taiwan Research Reactor (TRR). The pilot test shows that over 70% of low level metal waste can be decontaminated to very low activity and can be categorized as BRC (be… more

Underground reactor containments: An option for the future?

Description: Changing world conditions and changing technologies suggest that serious consideration should be given to siting of nuclear power plants underground. Underground siting is not a new concept. Multiple research reactors, several weapons production reactors, and one power reactor have been built underground. What is new are the technologies and incentives that may now make underground siting a preferred option. The conditions and technologies, along with their implications, are discussed herein. U… more

VENUS-2 MOX Core Benchmark: Results of ORNL Calculations Using HELIOS-1.4

Description: The Task Force on Reactor-Based Plutonium Disposition, now an Expert Group, was set up through the Organization for Economic Cooperation and Development/Nuclear Energy Agency to facilitate technical assessments of burning weapons-grade plutonium mixed-oxide (MOX) fuel in U.S. pressurized-water reactors and Russian VVER nuclear reactors. More than ten countries participated to advance the work of the Task Force in a major initiative, which was a blind benchmark study to compare code benchmark ca… more

FFTF Event Fact Sheet root cause analysis calendar year 1985 through 1988

Description: The Event Fact Sheets written from January 1985 through mid August 1988 were reviewed to determine their root causes. The review group represented many of the technical disciplines present in plant operation. The review was initiated as an internal critique aimed at maximizing the ``lessons learned`` from the event reporting system. The root causes were subjected to a Pareto analysis to determine the significant causal factor groups. Recommendations for correction of the high frequency causal f… more

The RERTR program.

Description: The Reduced Enrichment Research and Test Reactor (RERTR) Program was established in 1978 at the Argonne National Laboratory (ANL) by the Department of Energy (DOE), which continues to fund the program and to manage it in coordination with the Department of State (DOS), the Arms Control and Disarmament Agency (ACDA), and the Nuclear Regulatory Commission (NRC). The primary objective of the program is to develop the technology needed to use Low-Enrichment Uranium (LEU) instead of High-Enrichment … more

PT-IP-659-AC, Supplement A transition to normal discharge plan using striped target columns

Description: The scheduled termination of PT IP-659-AC, presently being irradiated in F Reactor, will result in discharge of 105 columns of enriched uranium (0.947 w/o U-235) at less than 50 per cent of the goal exposure. The test block is currently scheduled to be replaced with natural uranium columns. Since F Reactor is on a semiblock discharge plan (alternate rows), subsequent operating plans would require that 64 of these replacement columns of natural uranium be likewise discharged during the scheduled… more

Justification for extending scram recovery time at C Reactor

Description: Slug ruptures at C Reactor are costing a considerable amount of production and are limiting reactor power levels. A large portion of this production is lost because the ``quickie`` procedure cannot be used with unstruck ruptures. Currently there are two reasons for this condition: Insufficient reactivity is available to recover after a rupture is removed with the ``quickie`` equipment, and if the ``quickie`` method were attempted, there would be many failures due to stuck rear caps and improper… more

Charge-discharge during pile operation

Description: This document presents a general analysis of charge-discharge during pile operation. It is not a detailed technical, operational, economic, or political analysis but, rather an attempt to cover the subject with a broader viewpoint than is usually prsented in the many detailed reports which have been written in the past five years. This letter is occasioned at this time because efforts are in progress to implement plans for proceeding with the expenditure of substantial amounts of money in order… more

An Innovative Hybrid Loop-Pool SFR Design and Safety Analysis Methods: Today and Tomorrow

Description: Investment in commercial sodium cooled fast reactor (SFR) power plants will become possible only if SFRs achieve economic competitiveness as compared to light water reactors and other Generation IV reactors. Toward that end, we have launched efforts to improve the economics and safety of SFRs from the thermal design and safety analyses perspectives at Idaho National Laboratory. From the thermal design perspective, an innovative hybrid loop-pool SFR design has been proposed. This design takes ad… more

Special disarmament study

Description: This study investigates the cost of shutting down and later starting up the Hanford production complex. Also included are comments on two aspects, other than cost, which are consider to be of great importance. One is the impact of a complete shutdown on the Tri-Cities community. The other is the effect on Battelle`s Pacific Northwest Laboratory. This study encompasses six special shutdown-startup cases. One set of three cases assumes a shutdown of three years; the other set assumes the reactors… more
