Cold trap requirements for PHTS and IHTS sodium purification

Description: Cold trap requirements for the Primary Heat Transfer System (PHTS) and the Intermediate Heat Transfer System (IHTS) are defined. The bases for these requirements are (1) maintaining concentrations of oxygen and hydrogen within given limits, (2) controlling the transport of tritium by coprecipitating it in cold traps together with hydrogen, and (3) providing the necessary volume capacity for collecting impurities. It is concluded that the 60 gpm, FFTF Type I, NaK cooled, cold trap will satisfy t… more

Improved resonance reaction rate calculation for lattice physics subsystem

Description: The resonance capture calculations of the HAMMER System and HAMBUR System are derived from a consistent statement of the integral slowing down equation and definitions of the resonance integral. The assumptions made in these treatments are explicitly stated, and and an attempt is made to estimate the possible error in the resonance integral arising from these assumptions. This analysis is made to pin-point those parts of the calculation that can be improved and updated. Based on the analysis of… more

Determination of threshold velocities and correlation of high-frequency endurance limits for LMFBR heat-exchanger materials

Description: Jet impact erosion tests and high frequency fatigue tests were conducted for 2-1/4 Cr-1 Mo steel. Utilizing the relationship between the velocity of impact and number of impacts to produce visible erosion, the threshold velocities were determined as 220 and 140 fps at 10/sup 7/ and 10/sup 8/ cycles respectively. The relationship between the high frequency fatigue strength and the number of cycles to failure was determined at room temperature up to a maximum of 10/sup 9/ cycles. The high frequen… more

Preliminary safety analysis of the B-C Cribs Controlled Area. [Hanford Reservation]

Description: Approximately 2,000 acres of land in the center of the Hanford Reservation is contaminated with an estimated 14 Ci of /sup 137/Cs and 81 Ci of /sup 90/Sr associated with animal wastes. Approximately half of this activity is located on (or within) 2.5 centimeters of the ground surface. The source of the contamination was the B-C Cribs and trenches which were used as liquid radioactive waste disposal sites during the 1950's. The mechanism for movement of radionuclides from the disposal site to th… more
