Seismic Safety Margins Research Program: Phase II program plan (FY 83-FY 84) (open access)

Seismic Safety Margins Research Program: Phase II program plan (FY 83-FY 84)

The Seismic Safety Margins Research Program (SSMRP) is an NRC-funded, multiyear program conducted by Lawrence Livermore National Laboratory (LLNL). Its goal is to develop a complete, fully coupled analysis procedure (including methods and computer codes) for estimating the risk of an earthquake-caused radioactive release from a commercial nuclear power plant. The analysis procedure is based upon a state-of-the-art evaluation of the current seismic analysis and design process and explicitly includes the uncertainties inherent in such a process. The results will be used to improve seismic licensing requirements for nuclear power plants. As currently planned, the SSMRP will be completed in September, 1984. This document presents the program plan for work to be done during the remainder of the program. In Phase I of the SSMRP, the necessary tools (both computer codes and data bases) for performing a detailed seismic risk analysis were identified and developed. Demonstration calculations were performed on the Zion Nuclear Power Plant. In the remainder of the program (Phase II) work will be concentrated on developing a simplified SSMRP methodology for routine probabilistic risk assessments, quantitative validation of the tools developed and application of the simplified methodology to a Boiling Water Reactor. (The Zion plant is a …

4X6" Rotary Bayonet LN2 Test Fill (open access)

4X6" Rotary Bayonet LN2 Test Fill

This engineering note describes a test fill of the 4-inch x 6-inch rotary bayonet test fixture with LN{sub 2}. This test verifies the operation of valves on the fixture, and checks for proper construction/insulation. Further cold testing is imminent (with rotation and moment loading of the bayonet) after proper construction is verified and the test fixture is accepted. While this test fixture is a pressure vessel (4-inch), it does not require special safety treatment because it is under 6-inch in diameter. Flow capacity calculations were done to insure that the relief valve chosen would be capable of handling fire/loss of vacuum conditions. The D-Zero Safety Committee Chairman was notified of this testing.

Pulse to pulse beam trajectory determination at the IP (open access)

Pulse to pulse beam trajectory determination at the IP

It has long been known that a precise measurement of the SLC beam trajectory through the IP region is vital both from a machine and a detector point of view. One of the primary techniques used to maximize luminosity is the measurement of the deflection angle of one beam produced by the electromagnetic interaction with the other beam. In order to implement this procedure a pair of precision Beam Position Monitors (BPMs) were installed within the Final Triplet of quadrapoles on each side of the IP. Before the IP BPMs could be used to measure beam-beam deflection, a series of measurements were made of the coefficients which relate the setting of an orbit correction magnet to the position of the beam at a particular BPM (R/sub 12/s). The purpose was to expose any problems such as misconnected cables, etc., by comparing the measured R/sub 12/s with theoretical predictions from the model of the Final Focus region. A technique developed that uses position measurements in the long BPMs to determine a three parameter fit to the beam trajectory at the IP. The three parameters in the fit are the beam position, the incoming angle and the deflection angle. The result was …

Fire protection research for DOE facilities: FY 83 year-end report (open access)

Fire protection research for DOE facilities: FY 83 year-end report

We summarize our research in FY 83 for the DOE-sponsored project, Fire Protection Research for DOE Facilities. This research program was initiated in 1977 to advance fire-protection strategies of energy technology facilities in order to keep abreast of the unique fire problems that develop along with energy technology research. Since 1977, the program has broadened its original scope, as reflected in previous year-end reports. We are developing an analytical methodology through detailed study of fusion energy experiments at Lawrence Livermore National Laboratory (LLNL). Using these experiments as models for methodology development, we are currently advancing three major task areas: (1) the identification of fire hazards unique to fusion energy facilities, (2) the evaluation of accepted fire-management measures to meet the negate hazards, and (3) the performance of unique research into problem areas we have identified to provide input into analytical fire-growth and damage-assessment models.

Task 3 -- Bench-scale char upgrading and utilization study (open access)

Task 3 -- Bench-scale char upgrading and utilization study

This report describes the results of the bench-scale char upgrading study conducted as Task 3 of Development of an Advanced, Continuous Mild Gasification Process for the Production of Coproducts. A process where the char is gasified to produce methane in a first stage reactor was investigated. This methane is then decomposed to produce carbon and hydrogen for recycle in a second stage. The results indicate that both reaction steps are feasible using mild gasification char as the starting feedstock. Conditions for methanation are 700 to 800 C and 200 to 400 psig. Carbon formation conditions are 1,200 to 1,400 C at atmospheric pressure. The carbon produced has properties similar to those of carbons which are commercially marketed as carbon black.
