OXYGEN 18 EXCHANGE REACTIONS OF ALDEHYDES AND KETONES

Description: Using infra-red spectroscopy, the equilibrium exchange times have been determined for a series of ketones, aromatic aldehydes, and {beta}-ketoesters reacting with oxygen 18 enriched water. These exchange times have been evaluated in terms of steric and electronic considerations, and applied to a discussion of the exchange times of chlorophylls a and b and chlorophyll derivatives.

KE downcomer development Test-IP-778

Description: This test was performed to investigate the effects of increased reactor flow upon the downcomer pressures and water levels. Recent theoretical studies had confirmed earlier ones that indicated a relatively weak downcomer approach box structure with an allowable working pressure of 4 psig. Since a flooded approach box would yield pressures in excess of 4 psig on the lower approach box plates and since downcomer flows approaching the flooding point were planned, experimental values of the downcom… more

Thorium processing nuclear safety review

Description: A review of the nuclear safety aspects of a proposal to process about 150 to 250 tons of thorium containing about one kilogram U-233 per ton has been made. The review was made at the request of the Chemical Processing Department in whose Purex plant the thorium processing will be carried out. The review group finds that the proposed operation can be conducted with no more risk of criticality than attends the standard plutonium processing in Purex, provided the safeguards planned by the Departme… more
