WIPP conceptual design report. Addendum F. HVAC systems energy analysis for Waste Isolation Pilot Plant
This report presents the results of a technical and economic analysis of alternative methods of meeting the heating, ventilating, and air conditioning requirements of the Waste Isolation Pilot Plant (WIPP) facilities proposed to be constructed in southeastern New Mexico. This report analyzes a total of ten WIPP structures to determine the most energy and economic efficient means of providing heating, ventilating, and air conditioning services. Additional analyses were performed to determine the merits of centralized versus dispersed refrigeration and heating facilities, and of performing supplemental domestic hot water heating with solar panels.

Workshop on rock mechanics issues in repository design and performance assessment
The Center for Nuclear Waste Regulatory Analyses organized and hosted a workshop on ``Rock Mechanics Issues in Repository Design and Performance Assessment`` on behalf its sponsor the U.S. Nuclear Regulatory Commission (NRC). This workshop was held on September 19- 20, 1994 at the Holiday Inn Crowne Plaza, Rockville, Maryland. The objectives of the workshop were to stimulate exchange of technical information among parties actively investigating rock mechanics issues relevant to the proposed high-level waste repository at Yucca Mountain and identify/confirm rock mechanics issues important to repository design and performance assessment The workshop contained three technical sessions and two panel discussions. The participants included technical and research staffs representing the NRC and the Department of Energy and their contractors, as well as researchers from the academic, commercial, and international technical communities. These proceedings include most of the technical papers presented in the technical sessions and the transcripts for the two panel discussions. Selected papers have been indexed separately for inclusion the Energy Science and Technology Database.

X-ray tomographic microscopy for non-destructive inspection and advanced materials characterization. Final report, May 22, 1992--May 21, 1994
This was a CRADA to transfer the x-ray tomographic microscope technology to the Quality Technology Center of General Electric Air Craft Engines Division in Ohio. The x-ray tomographic microscope (XTM) is a high resolution, three-dimensional imaging system that can be used to image materials microstructures noninvasively. The apparatus consists of an x-ray source, x-ray collimators, sample positioning stages, a fluorescent screen to convert x-rays to visible light, an optical lens, and a thermoelectrically cooled charge coupled device detector. The details of the microscope`s design have been described elsewhere. In practice, the sample to be imaged is positioned on a rotating stage. The sample is initially translated out of the x-ray path, and an image is obtained of the incident x-ray beam (the reference image). Next, the sample is placed between the x-ray path and the scintillator, and another image, the projection image, is acquired. The ratios of the logarithms of the reference image and the projection image provide values of the integrated x-ray attenuation through the sample. By rotating the sample in discrete angular increments through 180 degrees, enough data can be obtained to reconstruct the two-dimensional projection images into a three-dimensional image of the mineral density distribution in the …

Xenon and Samarium reactivity effects associated with coolant loss
In Hanford reactors the reactivity gain upon loss of coolant water is an important factor in the speed of control requirements. The reactivity gain in the cold, clean reactor is determined from experiments, but additional effects must be taken into account if the gain in the operating reactors is to be obtained. One of these effects is the change in Xenon and Samarium poisoning with neutron temperature, which is discussed here. Earlier work on the relationship of operating limits to the reactivity gain upon loss of coolant is given in Reference 1. Work on this problem is continuing by Reactor Physics, IPD, but the newer work is not yet documented. In earlier calculations, the neutron temperature could only be guessed. Recent measurements of neutron temperatures have indicated the magnitude of the neutron temperature change upon loss of water. This document interprets the data of Reference 2 in terms of the change in Xenon and Samarium poison to be expected on water loss under typical operating conditions.

XENON TRANSIENT. CORE 1, SEED 1, EFPH 4947.6. Section 1. Test Results T-612081
Tests were conducted to determine if sufficient reactivity was in the core to override a pesk xenon transient. After 4947.6 EFPH, there was not enough excess reactivity to override the poisoning with all rods fully withdrawn. (B.O.G.)

Xenon Transient. Core 1, Seed 1. Test Results T-612081. Section 1
A test was conducted to determine if there is sufficient excess reactivity after 5532.3 EFPH for Core 1 Seed 1 to override a Xe transient, and to obtain data for rod worth calculations. The core did not contain enough reactivity to override Xe poisoning during the first 35 hrs after shutdown. As a result, the point at which peak Xe occurred could not be determined. Data on rod worth are included. (J.R.D.)

XENON TRANSIENT. CORE I, SEED 1, EFPH 2790.5. Section 1. Test Results T-612081
A test on the Shippingport PWR was described, whose purposes were to determine if sufficient reactivity was present in the core to override a peak xenon transient, and to obtain data for rod worth calculations. Equilibrium xenon was established at 60 Mw net electrical output for approximately 35 hours prior to shutdown. The flux was then reduced to approximately 100 mu mu a. The reactor was maintained critical by withdrawing or inserting rods as necessary. Startup rates were measured by a mu mu ammeter. The xenon transient was followed in this manner for 60 hours. Override of peak xenon occurred 8 hr 50 min after shutdown. (auth)

XENON TRANSIENT TEST. CORE 1, SEED 2. Test Results T-612081. Section 3
CORE 1, SEED 2. Test Results T-612081. Section 3. (Duquesne Light Co., Shippingport, Penna.). First issue, Apr. 20, 1961. 28p. . The reactor was operated at full power to obtain equilibrium xenon concentration and then shutdown for 8 1/2 hr to obtain peak xenon concentration. It then was brought to 75 and then 67% of full power; the xenon concentration returned to an equilibrium value 4 hr after reactor startup. There was no apparent effect on the nuclear instrumentation caused by xenon concentration changes. Values of rod worth were determined, and operating characteristics during the test are given.

You have the power. 1997 Federal Energy Management Program report
From 1985 to 1996, the Federal investment in energy efficiency totaled $2 billion. This investment achieved a cumulative savings of $6.3 billion in the nation`s energy bill when calculated from a 1985 baseline. The Energy Policy Act of 1992 and Executive Order 12902 require a rate of even greater energy savings than the pace already set. FEMP`s leadership and accomplishments for FY 1997 have helped Federal agencies meet their challenges and attain their goals by: increasing partnerships with the private sector; providing cost effective quality services and tools; integrating energy efficiency into procurement; increasing Federal employee energy awareness; influencing outcomes by promoting good energy habits; and increasing the number and scope of energy efficiency projects.

Yucca Mountain and The Environment
The Yucca Mountain Project places a high priority on protecting the environment. To ensure compliance with all state and federal environmental laws and regulations, the Project established an Environmental Management System. Important elements of the Environmental Management System include the following: (1) monitoring air, water, and other natural resources; (2) protecting plant and animal species by minimizing land disturbance; (3) restoring vegetation and wildlife habitat in disturbed areas; (4) protecting cultural resources; (5) minimizing waste, preventing pollution, and promoting environmental awareness; and (6) managing of hazardous and non-hazardous waste. Reducing the impacts of Project activities on the environment will continue for the duration of the Project.
