The Palmolive cycle at Hanford

Description: The Palmolive program is directed toward the recovery of neptunium-237 and production of plutonium-238. The neptunium is recovered during the chemical processing of irradiated uranium and is purified and fabricated into target elements. The target elements are irradiated to produce plutonium-238 by neutron capture of neptunium-237 and are processed to provide plutonium for shipment to the final customer and neptunium for recycle within the system. This report summarizes a preliminary engineerin… more

Report on preliminary laboratory experiments investigating consequences of failure of front hydraulic fittings in K reactor geometry

Description: The purpose of this report is to present the results of a brief series of transient heat transfer experiments directed toward determining the possibility of damage to a K reactor should a front hydraulic connector fail to a tube containing I&E fuel elements. Nuclear heating of a train of 32 I&E slugs was simulated by electrically heating a rod in a K geometry process tube. Failure of a front fitting to such a tube was simulated by simultaneously and rapidly closing a valve in the water supply t… more

SOLIDS ACCUMULATION AND FISSION HEATING IN THE HRT CHEMICAL PLANT UNDERFLOW POT (CO-OP REPORT, FALL QUARTER, 1958)

Description: A study was conducted to develop equations for calculating fission product heating in the RRT-CP undeflow pot from measured temperatures and to attempt to correlate the rate of solids accumulation in the undeflow pot with flssion heating and reactor power. Using fission heating data calculated from the heat balances developed, several semi-empirical equations relating solids accumulation and heating were tested. In one case an error of no greater thaQ 26% was incurred in the calculation of the … more

Study of Factors Influencing Ductility of Iron-Aluminum Alloys. Monthly Letter Report No. 7

Description: The objective of the program is to determine the effect of variations of Al content, heat treatment, and basic slip mechanism upon the room temperature ductility of Fe - Al alloys. Additional heat treatment studies on 13.9 Alfenol tends to confirm earlier observations that reproducibility of ductility values of 8 to 9% are difficult to obtain. The preparation of Al - Y - Fe, and Al - Mo - Y - Fe alloys by arc melting in a non-consumable electrode arc furnace is reported. A resistivity versus te… more

Determination of Li6 in Aqueous Solution by Neutron Activation Analysis

Description: A method for determining the concentration of Li6 in aqueous solution has been tested using the nuclear reactions Li6 (n,α)H3 and O16 (H3,n)F18. Annihilation 7 radiation of induced 1.87 hour F18 radioactivity was counted with a well-type scintillation counter, and the radioactivity per millimole of lithium was found to be independent of lithium concentration below about 0.2moles/liter. The sensitivity limit for detecting lithium is less than 0.1 micromole (0.0075 micromole Li6).

A Theoretical and Experimental Investigation of the Temperature Response of Pig Skin Exposed to Thermal Radiation

Description: Estimates indicate that first degree burns on the bare skin will be sustained 30 miles from a 10 megaton nuclear blast. Results are reported from a theoretical and experimental investigation of the temperature response of pig skin exposed to thermal radiation. While the study deals with radiant energy heating of skin, it is concluded that results may be applied to other modes of energy input. Methods were developed for the comparison of theoretical predictions with experimental results. An atte… more
