Rear face hardware replacement 105-B, D, DR, F, and H

Description: Prior to the use of venturis on the front of the B, D, DR, P, and H Reactors, much of the pressure and velocity heads developed by the 190 process water pumps were used in overcoming built-in frictional losses in the system external to the process tubes. As Reactor Technology was gained, changes were continually taking place. Venturis replaced orifices installed during original construction. Hydraulically efficient front nozzles, front pigtails, front adaptors, and a second generation of front … more

FUEL ELEMENT GRAPPLE AND FUEL ELEMENT HOLD-DOWN LATCH DEVELOPMENT--LARGE SGR FUEL HANDLING

Description: A fuel element hold-down device, which is an integral part of the fuel element assembly, was developed to lock reactor fuel to the bottom grid plate. Concurrently with the hold-down latch development, a fuel bandling machine grapple capable of setting, releasing, and checking the hold-down device was developed. (auth)

Campaign rework of Z-Plant material at Purex

Description: The Purex Plant has been requested to process Z-Plant MR and EPT solutions containing about 200 kilograms of plutonium in order to alleviate processing problem at Z-Plant and to reduce the inventory of MR and EPT rework. Campaign recycle of uranium through the main plant is recommended as an economical and effective means of reworking large quantities of Z-Plant plutonium solutions. This memorandum outlines process alternates and costs for reworking the solutions and itemizes specific recommend… more

PITA IP-27C: Part 2, Increased coolant flow, H reactor operational physics requirements

Description: A program for increasing the available coolant flow at the H Reactor has been proposed and supported by documentation. This Process Improvement Transition Authorization (being written in two parts) authorizes the initiation of an immediate phase of the program designed to increase total coolant flow by about 6,000 to 10,000 gallons per minute. Part I of this PITA describes in detail the limitations and requirements peculiar to Process Engineering aspects of the proposed modifications and is pre… more

Measurement of Spectral Distribution of Positron Flux in an Infinite Copper Medium Containing Cu$sup 64$

Description: The spectral distribution of the flux of positrons inside a beta radioactive medium was experimentally determined using an anthracene coincidence scintillation spectrometer. Positrons leaving a copper cavity source containing Cu/sup 64/ were absorbed in a thin anthracene crystal. The light pulse from the anthracene was recorded in a 256 channel analyzer if a NaI scintillation spectrometer nearby recorded simultaneously a count under the total absorption peak for annihilation radiation. Thus, di… more

PATHFINDER ATOMIC POWER PLANT. BURNUP LIMITS FOR PATHFINDER TWO WEIGHT PER CENT NATURAL BORON-STAINLESS STEEL CONTROL RODS

Description: A survey of literature on irradiation experience with boron stainless steel was conducted to determine the effect of neutron irradiation and boron-10 burnup on the two weight per cent natural boron stainless steel control rods being used in the Pathfinder reactor. The literature reviewed included irradiation test samples and full-size control rods in operating reactors. From the analysis of the survey, it was concluded that the Pathfinder control rods will operate satisfactorily and retain thei… more
