Experimental Evaluation of Tude Support Plate Crevice Chemistry

Description: A test methodology for measuring temperature, impedance, pH, and electrochemical potential distributions within a sludge-packed tube support plate crevice in a laboratory test is described. The method successfully showed that there were large concentration gradients between the tube and tube support plate sides of the crevice. The testing also showed that strong bases concentrated more effectively than strong acids, and that the crevice pH, when exposed to seawater-based solutions, increased wi… more

NPR design basis

Description: The design basis is composed of requirements and conditions for the design of the reactor plant (composed of the reactor and heat dissipation system). Its intent is to insure that the final product meets the economic, safety, and technical objectives of the project. The design basis is dependent on the ground rules, objectives, technical criteria, and practical design considerations. This document is being issued with the understanding that these items are not yet firmly established in all resp… more

Analysis and testing of rupture of steam generator tubing with flaws.

Description: A high-temperature (300 C), high-pressure (18 MPa), and high-leak rate (1500 L/min) facility, and a room temperature, high-pressure (52 MPa) test facility were used to test flawed steam generator tubes. Single and multiple rectangular flaws were fabricated by electro-discharge machining on the outside surface of the tubes. This paper briefly reviews analytical methods for predicting ligament rupture and unstable burst of tubes with single and multiple rectangular flaws. Test data are presented … more

Reference klystron output phase values for the first ten linac sectors

Description: The purpose of this note is to provide phase reference values for klystrons in the first ten linac sectors to be used as tentative start-up values next September and to point out the degree of long term phase stability of the klystrons as well as the possibility of implementing closed loop feedback stabilization.

Analysis for Eccentric Multi Canister Overpack (MCO) Drops at the Canister Storage Building (CSB) (CSB-S-0073)

Description: The Spent Nuclear Fuel (SNF) Canister Storage Building (CSB) is the interim storage facility for the K-Basin SNF at the US. Department of Energy (DOE) Hanford Site. The SNF is packaged in multi-canister overpacks (MCOs). The MCOs are placed inside transport casks, then delivered to the service station inside the CSB. At the service station, the MCO handling machine (MHM) moves the MCO from the cask to a storage tube or one of two sample/weld stations. There are 220 standard storage tubes and si… more

Resonance Control Cooling System for the APT/LEDA CCDTL Hot Model

Description: The Hot Model for the Coupled Cavity Drift Tube Linac (CCDTL) resonance control cooling system (RCCS) for the Low Energy Demonstration Accelerator (LEDA) [1] in support of the Accelerator Production of Tritium (APT) [2] is described. Two hydraulic control loops are described that control the frequency in the CCDTL Hot Model cavity. The two loops supply the required flow to the 32 channels. Control system schema is described to regulate resonant frequency during steady state operation.

Analysis for Eccentric Multi Canister Overpack (MCO) Drops at the Canister Storage Building (CSB) (CSB-S-0073)

Description: Multi-Canister Overpacks (MCOs) containing spent nuclear fuel (SNF) will be routinely handled at the Canister Storage Building (CSB) during fuel movement operations in the SNF Project. This analysis was performed to investigate the potential for damage from an eccentric accidental drop onto the standard storage tube, overpack tube, service station, or sample/weld station. Appendix D was added to the FDNW document to include the peer Review Comment Record & transmittal record.

Amorphous Diamond Flat Panel Displays - Final Report of ER-LTR CRADA project with SI Diamond Technology

Description: The objective of this project was to determine why diamond-based films are unusually efficient electron emitters (field emission cathodes) at room temperature. Efficient cathodes based on diamond are being developed by SI Diamond Technology (SIDT) as components for bright, sunlight-readable, flat panel displays. When the project started, it was known that only a small fraction (<1%) of the cathode area is active in electron emission and that the emission sites themselves are sub-micron in si… more

Concepts for General-Purpose Under Sodium Scanning Systems

Description: The development of the concepts for general-purpose scanning systems is discussed, based on the consideration of ultrasonics operating in liquid sodium. Technical information and data, such as ultrasonic attenuation in liquid sodium, piezoelectric materials operating in 600 F sodium, ect., are provided from theoretical and experimental studies. The report also includes explanations, analyses, and applications of the single-narrow-beam scanning systems and the electronic acoustic image conversio… more
