Examination of T-111 clad uranium nitride fuel pins irradiated up to 13,000 hours at a clad temperature of 990/sup 0/C
The examination of 27 fuel pins irradiated in the Plum Brook reactor facility is described. Curtailment of NASA sponsored nuclear programs prevented a complete examination of all pins. Nevertheless, results include fuel pin integrity, clad ductility, clad strain, fission gas release, fuel burnup, fuel swelling, neutron fluence, metallography, and instrumentation reliability. Twenty-two fuel pins were tested for fission gas leaks; 13 pins leaked with two having visible cracks. Fuel swelling appeared to be primarily burnup dependent for burnup values up to 2 at. %. Maximum burnup reached in these tests was 2.34 at. %. In general, the fuel pellets did not crack or crumble and fuel metallography remained unchanged. The amount of fission gas released from the fuel was low, generally less than 0.5%. The maximum amount released was 2%. No incompatibilities between fuel, liner, and clad were evident.

Effect of component performance perturbations on the efficiency of injection of neutral beams into thermonuclear reactors
From 5th symposium on engineering problems of fusion research; Princeton, New Jersey, USA (6 Nov 1973). The effect of component performance perturbations on the efficiency of injection of neutral beams into thermonuclear reactors is discussed for a specific type of a neutral beam injector. Based on the model chosen, which includes using direct conversion of the unneutralized portions of the ion beam and recovery of the losses from each element of the injector system, quantitative effects of component performance perturbations are presented as a function of the injected deuterium atom energy, using positive and negative deuterium ions. The component performances having the largest leverage on the system efficiency are, in decreasing order, the accelerator efficiency, the trapping fraction, the neutralizer loss direct conversion, and the neutralizer power efficiency.

Diffraction dissociation in 205 GeV/c $pi$$sup -$p two- and four-prong interactions
From meeting of the division of particles and fields; Berkeley, California, USA (13 Aug 1973). Data are presented on diffraction dissociation in pi /sup -/p yields pi /sup -/p and pi /sup -/p yields pi /sup -/ pi /sup - / pi /sup +/p interactions at 205 GeV/c. Mass spectra and cross sections for pion dissociation and nuclear dissociation are presented. (LBS)
