The Boron-Carbon System: Quarterly Report Number 3, November 1960 - January 1961

Description: Abstract: A definitive investigation of the boron-carbon equilibrium system is being made by X-ray diffraction, metallographic, and thermal analytical techniques. On the basis of metallographic and X-ray diffraction studies it is concluded that boron carbide has a range of solubility from approximately 10 to 20 atomic per cent carbon at 1500 degrees to 2000 degrees Celsius. The melting point of the carbide-graphite eutectic has been established as 2325-2350 degrees Celsius. No reversible allotr… more

Production Test IP-467-C reducing minimum downtime

Description: The objective of the Production Tests described in this report is to evaluate the operational aspects of a proposed method for reducing minimum downtime. The excess xenon poisoning, which occurs during the first 32--38 hours after the shutdown of a reactor from present equilibrium levels, will be partially overridden by a central enriched zone whose added reactivity contribution would be compensated during normal operation by means of poison splines. The test will be performed at B Reactor.

Supplementary report of preliminary testing production test IP-234-AE: Supplement 2, Project CG-775, prototype testing of the 190-K process pumping units

Description: It was necessary to provide a basis for the design of modifications to the 190-K pumping units to achieve increased process water flow rates. The prototype pumping unit was inspected for cavitation damage after 3 months operation. The low lift pump impeller showed no cavitation damage, while the high lift pump impeller showed excessive damage. The lower max flow capacity and slightly increased power requirements of the third prototype impeller should not preclude its use if its cavitation perfo… more

Production test IP-338-A: DR-reactor heat decay test at high outlet water temperatures

Description: This test is designed to obtain up-to-date information on heat decay values following a reactor scram. More specifically its purpose is to determine the effect of increased outlet water temperatures upon this heat output value. A recent review of the ``last ditch`` cooling system at the Hanford reactors indicated that at some reactors this backup coolant supply did not meet our coolant adequacy criteria at certain critical times after the loss of electric and steam pumping power. On the basis o… more

Supplement B, production test IP-377-A, irradiation of N-Reactor inner fuel tubes in the KER loops

Description: The objective of this supplement to Production Test IP-377-A is to evaluate the behavior of N Reactor inner fuel tubes with modified end closures during irradiation in the KER Loops. Natural and 0.947% enriched N Reactor inner fuel tubes (NINl and NIEl elements) with contoured end closures are authorized for irradiation in the KER Loops to exposures no greater than 2500 MWD/T. The modification consists of machining a V groove in the uranium after counterboring and using an end cap shaped to fit… more

Design of Production Test IP-381-A-FP, Irradiation of oversize fuel elements in the C Reactor overbored process channel facilities

Description: Recent studies have confirmed that large incentives exist for overboring the reactor process channels approximately 500 mils in the C and five old reactors, under the updated Plant Improvement Program. Conservative estimates of the incentives for overboring indicate a payout period of about two years for the proposed work, an increase in plutonium production of 15--18%, derived from increased conversion ratio and a reduction in plant unit cost. The proposal to overbore the graphite channels app… more

Norfolk-Peninsula Area (ARMS-II)

Description: From Introduction: "The ARMS-II Norfolk - Peninsula area survey was one many that have been flown for the CETO since the nationwide ARMS program was started (1958). Figure 2 shows the location of the areas that have been completed to date. The purpose of the program is to measure the present environmental levels of gamma radiation in areas around nuclear facilities and planned nuclear activities."

Bibliography of Temperature Measurement: January 1953 to June 1960

Description: Report presenting more than 500 references to the field of temperature measurement. These references were collected from two general sources: Scientific and technical literature and government reports. The period covered is from 1953 to June 1960, with some from earlier dates. References are divided into a number of categories based on the type of instrument used. Some references to calibration of instruments and to scientific theories upon which temperature measurement is based are also presen… more

Summary of Runs 1, 2, and 3 in High-Temperature, High-Pressure Titanium Loop

Description: Simulated reactor fuel solutions were circulated at temperatures as high as 365°C in a small titanium pump loop. A hydroclone separator separated heavy phases formed at high temperatures. As the temperature of the solution was increased beyond the two-liquid-phase temperature (327°C), the salt concentration of the light phase decreased and the acid concentration increased. The mole ratios of uranium to sulfate, uranium to copper, and uranium to nickel in the light phase decreased in the same pr… more
