PILOT PLANT SHUTDOWN AND Pu-Al PROCESSING

The large aqueous pilot plant facilities at ORNL were cleaned and are being put in standby condition. Experience was gained during the year as anion exchange was used to recover more than one kg of plutonium left in the exploded evaporator system. This experience is being applied to a new recovery program just beginning in cell 1 of Building 4507. (auth)

EXPERIMENTAL MEASUREMENTS OF THE SUCTION HEAD REQUIRED BY THE HALLAM PROTOTYPE FREE SURFACE SODIUM PUMP (open access)

EXPERIMENTAL MEASUREMENTS OF THE SUCTION HEAD REQUIRED BY THE HALLAM PROTOTYPE FREE SURFACE SODIUM PUMP

Hydraulic tests were made on the Hallam Prototype Free-Surface Sodium Pump to determine the net positive suction head (NPSH) required at various sodium flow rates. Pump performance data were also collected. The results indicate that an NPSH of 22 ft sodium is required at the design flow rate of 7200 gpm at approximates 1000 deg F, agreeing with computed values, and that the pump is designed with a safety margin of slightly over l0%.

Flood Safety of the Mixed Spectrum Superheater (open access)

Flood Safety of the Mixed Spectrum Superheater

Calculations are presented which show that the reactivity effect of flooding and unflooding the fast superheating section of the Mixed Spectrum Superheater can be made small by the addition of epithermal poisons to the superheater. The reactivity effects of flooding superheater sections ranging in size from 1.25 to 3.5 ft cubes and containing U/sup 23/5/sup >/oxide or Pu/sup 239/ oxide fuel and various amounts o f the epithermal poison europium were calculated. Reactivity changes during several postulated flooding processes are given. Methods for deterthination of fissile and fertile material and poison cross sections in the resonance- region are discussed.

Low level waste treatment by ion-exchange. II. Use of a weak acid, carboxylic-phenolic ion-exchange resin

Laboratory results are presented for a flowsheet study of a process for decontaminating ORNL low level waste water. The water is adjusted to approximately pH 12 with NaOH, clarified, and passed through a bed of phenolic cation exchange resin. This study, using a phenolic-carboxylic resin, showed essentially the same results as those previously reported using a phenolic-sulfonic resin, i.e., radioactivities in ORNL waste were reduced to the order of 10% of MPC. The phenolic-carboxylic resin has the advantage that it can be regenerated with 0.5 M HNO/sub 3/ instead of the 5 M HCl required for the phenolic-sulfonic resin. Volume reduction factors of 2000 to 3000 were achieved.

THE Epsilon*/Lambda BRANCHING RATIO OF Y*1 (open access)

THE Epsilon*/Lambda BRANCHING RATIO OF Y*1

Recently a T = 1 resonance in the {Lambda}{pi} system called Y*{sub 1} has been observed with a mass of 1385 Mev. Two types of resonances have been predicted that might relate this observation to other elementary-particle interactions: (1) P 3/2 resonances in the {Lambda}{pi} and {Sigma}{pi} systems predicted by global symmetry corresponding to the (3/2, 3/2) resonance of the {pi}N system; (2) a spin-1/2 Y-{pi} resonance resulting from a bound state in the KN system. The position and width of the observed Y*{sub 1} resonance agree with both theories, but since the spin and parity have not yet been determined, it is impossible at present to distinguish between the two theoretical interpretations.

Proposal for charging the sixth rupture fuel element experiment: GEH-10, 46, 47 (open access)

Proposal for charging the sixth rupture fuel element experiment: GEH-10, 46, 47

The objective of the test discussed in this report is to verify further the corrosion rate of irradiated tubular fuel elements under conditions of high specific power and central core temperatures. The fuel will be the inner component of an NPR fuel element assembly. A proposal to charge two tubular fuel elements into the GEH-P7 Loop has been made. The upper fuel element of the two has been irradiated to 1660 MWD/T in a Hanford reactor. A hydraulic cylinder will be attached to the upper fuel element. The hydraulic cylinder will be used to move a chisel along the outer surface of the upper fuel element and shear off a cap which has been welded over a hole through the cladding. The lower fuel element of the two will be used to add heat to the loop so that the desired loop water temperatures can be maintained.

Simulation of the Zirflex Process With an Analog Computer (open access)

Simulation of the Zirflex Process With an Analog Computer

The Zirflex process was studied extensively at Hanford in the development of technology for the interim reprocessing of power reactor fuels. The process involves the dissolution of Zircaloy in aqueous ammonium fluoride - ammonium nitrate solution. It is of particular interest at Hanford because of the impending fuel recovery from Zircaloy-clad PRTR and NPR elements. The chemical kinetics of the Zirflex reaction were not fuily defined at the end of the original studies. However, a pseudo first order reaction with free'' fluoride (fluoride not complexed with Zr) was deemed to describe the kinetics adequately for engineering calculations. The refined kinetic equation and the analog computer solution on model of the system are discussed. The results of thirty computer simulated dis solutions are also presented, and the data are used to illustrate the effects of the process variables on the Zirflex dissolution time cycle. The data from a selected few of the runs are directly applicable to the reprocessing of PRTR fuel elements in Redox. It was found that the Zirflex reaction kinetics are dependent on free'' fluoride ion to the 2.0l7 power and on H ion to the 0.457 power according to laboratory data secured after completion of the original …

A Model for Fission-Gas Release From Porous Fuels in Low-Permeability Containers (open access)

A Model for Fission-Gas Release From Porous Fuels in Low-Permeability Containers

A simple mathematical model was developed to describe the steady-state release rate of gaseous fission products from porous ceramic fuels in low- permeability containers. The resulting equations are used to analyze experimental release rate results obtained from a UC/sub 2/-fueled graphite fuel body enclosed in a low-permeability impregnated graphite container. The relative release rates of the fission-product species Kr/sup 85m/, Kr/sup 88/, and Xe/sup 133/ were predicted with reasonable success. Absolute-rate predictions were not possible due to lack of information on true permeability and porosity profiles in the graphite container. (auth)

Radiation Levels in the Vicinity of the Purification Demineralizers. Core 1, Seed 2. Test Evaluation T-641306

Measurements were made to determine the extent of activity build-up inside the 1 AC and 1 BD punification demineralizer concrete enclosures. Radiation levels were obtained at 6-in. intervals from 6 to 17.5 ft below the top of the concrete shield on the 1 AC demineralizer and from 0.5 tc 24.5 ft on the 1 BD dendneralizer by lowering the probe through the 3-in. pipe on top of the concrete enclosure. The results indicated that the long-lived activity in the purification demineralizers had decreased considerably, since the previous test, with the addition of new resin. (M.C.G.)
