Abstract: A definitive investigation of the boron-carbon equilibrium system is being made by X-ray diffraction, metallographic, and thermal analytical techniques. On the basis of metallographic and X-ray diffraction studies it is concluded that boron carbide has a range of solubility from approximately 10 to 20 atomic per cent carbon at 1500 degrees to 2000 degrees Celsius. The melting point of the carbide-graphite eutectic has been established as 2325-2350 degrees Celsius. No reversible allotropy of the beta-rhombohedral structure has been observed. The solubility of carbon in boron is very small. The melting point of dilute carbon alloys is found to be essentially the same as that of pure boron (2040 degrees to 2050 degrees). No metallographic evidence of a three-phase reaction of dilute alloys is observed.

The objective of the Production Tests described in this report is to evaluate the operational aspects of a proposed method for reducing minimum downtime. The excess xenon poisoning, which occurs during the first 32--38 hours after the shutdown of a reactor from present equilibrium levels, will be partially overridden by a central enriched zone whose added reactivity contribution would be compensated during normal operation by means of poison splines. The test will be performed at B Reactor.

It was necessary to provide a basis for the design of modifications to the 190-K pumping units to achieve increased process water flow rates. The prototype pumping unit was inspected for cavitation damage after 3 months operation. The low lift pump impeller showed no cavitation damage, while the high lift pump impeller showed excessive damage. The lower max flow capacity and slightly increased power requirements of the third prototype impeller should not preclude its use if its cavitation performance proves satisfactory. Required combined five and six pump flow rates would be achieved with proper sizing of impeller diameter. Adequate margin of safety would exist between design operating points (five and six pump operating points) and max capacity. Under four pump operating conditions, the flow would be reduced 1% below that of the first impeller design, and the bulk outlet temperature surge would be increased one degree following instantaneous reduction to four pump operation.
