The experimental data on the multiplicity distributions for various kinds of secondaries produced in the proton-nucleus interactions in emulsion at 200 GeV/c and the correlations between them are presented and discussed. All the characteristics of heavy prongs (mean values <n{sub b}>, <n{sub g}>, <N{sub h}>, their distributions and correlations) are independent (or have a very weak dependence) on the collisions energy in the range 20-200 GeV/c. The data contradict to the cascade-evaporation model and qualitatively agree with the mechanism of particle emission via the long-lived intermediate states. The observed weak A-dependence ({approx} A{sup 0.15}) of shower particle distributions is in agreement with the calculated ones according to the simplified two-step model. It is shown that the n{sub s}-distributions agree well with KNO scaling law in the 67-200 GeV/c range, but the form of universal {psi}(n{sub s/n{sub s}})-function has a weak A-dependence.

The coherent diffraction production process is characterized by a very narrow angular distribution of secondary particles that is caused by a small 4-momentum transferred to the nuclei. Besides, they have neither excitation of nuclei, nor disintegration. The quantum numbers of the coherently produced system are the same as those of the incident particle. For proton coherent interactions the number of charged particles must be odd. In this work are presented the data about a cross section for production of three, five and seven charged particles at 200 Gev/c, the energy dependence of these cross sections as angular characteristics of the secondary particles in coherent reactions.

Three new experiments concerning coherent production from nuclei are discussed. Evidence is presented from the Carnegie Mellon-Illinois-Northwestern-Rochester collaboration regarding coherent production of A{sub 2} mesons in collisions of 23 GeV/c {pi}{sup -} with nuclear targets (C, Al, Cu, Ag). The coherent A{sub 2} cross section which vanishes in the forward direction is typically {approx} 2% that of the A{sub 1}. A neutron dissociation experiment conducted at BNL (Rochester-BNL collaboration) has studied the process n {yields} p{pi}{sup -} occurring coherently on nuclei. Using the optical model of Kolbig-Margolis a 30-40 mb cross section was extracted for the scattering of low-mass p{pi}{sup -} systems on nucleons for momenta of {approx} 13 GeV/c. A similar experiment conducted at FERMILAB (FNAL, University of Massachusetts, Northwestern, Rochester Collaboration) has indicated that at high energies ({approx} 200 GeV/c) Coulomb excitation of the neutron accounts for the major part of the reaction n + Pb {yields} (p{pi}{sup -}) + Pb. While p{pi}{sup -} production on C is dominated through Pomeranchukon exchange.

This Phase 0 report covers problem definition and systems requirements. Facilities will incorporate capability for research in component, system, and materials technology and a nominal 10 MWe experimental, binary cycle, power generating plant.

Cold trap requirements for the Primary Heat Transfer System (PHTS) and the Intermediate Heat Transfer System (IHTS) are defined. The bases for these requirements are (1) maintaining concentrations of oxygen and hydrogen within given limits, (2) controlling the transport of tritium by coprecipitating it in cold traps together with hydrogen, and (3) providing the necessary volume capacity for collecting impurities. It is concluded that the 60 gpm, FFTF Type I, NaK cooled, cold trap will satisfy the PHTS requirements. For each of the IHTS loops a single, 60 gpm, cold trap is required; and an aircooled trap similar to the FFTF Type I design except for a 3-foot longer crystallizer section has been chosen for this service.

The objectives of this program are to: (1) conduct static and dynamic tests to demonstrate or determine the mechanical performance of full-size (cross section) FFTF fuel transfer machine and reactor vessel head seals intended for use in a sodium vapor - inert gas environment, (2) demonstrate that these FFTF seals or new seal configuration provide acceptable fission product and cover gas retention capabilities at LMFBR Clinch River Plant operating environmental conditions other than radiation, and (3) develop improved seals and seal technology for the LMFBR Clinch River Plant to support the national objective to reduce all atmospheric contaminations to low levels.

The resonance capture calculations of the HAMMER System and HAMBUR System are derived from a consistent statement of the integral slowing down equation and definitions of the resonance integral. The assumptions made in these treatments are explicitly stated, and and an attempt is made to estimate the possible error in the resonance integral arising from these assumptions. This analysis is made to pin-point those parts of the calculation that can be improved and updated. Based on the analysis of existing calculations a method of calculation is derived which avoids most of the problems encountered in HAMMER and HAMBUR. The chief improvements that result are as follows: Careful attention is paid to calculation of the resonance flux as most errors in existing calculations result from consistently overpredicting fluxes in all regions of a lattice cell. The calculation can be modified to produce as crude or detailed a resonance calculation, at the expense of computer time, as required by the user. Resonances that overlap group boundaries contribute the correct contribution to each group's reaction rates. Overlap between resonances of different isotopes is correctly accounted for. Up-to-date resonance formalisms are used including the Adler-Adler multi-level formulations. Provision is made to easily add new …

Jet impact erosion tests and high frequency fatigue tests were conducted for 2-1/4 Cr-1 Mo steel. Utilizing the relationship between the velocity of impact and number of impacts to produce visible erosion, the threshold velocities were determined as 220 and 140 fps at 10/sup 7/ and 10/sup 8/ cycles respectively. The relationship between the high frequency fatigue strength and the number of cycles to failure was determined at room temperature up to a maximum of 10/sup 9/ cycles. The high frequency endurance limit at room temperature was determined to be approximately 32,000 psi for 10/sup 8/ cycles. In addition, the ratio of high frequency fatigue strength to water hammer stress for erosion inception was also obtained as 2.75. 5 figures.

A program is proposed for the ground demonstration, development, and flight qualification of a radioisotope nuclear heated dynamic power system for use on space missions beginning in the 1980's. This type of electrical power system is based upon and combines two aerospace technologies currently under intense development; namely, the MHW isotope heat source and the closed Brayton cycle gas turbine. This power system represents the next generation of reliable, efficient economic electrical power equipment for space, and will be capable of providing 0.5 to 2.0 kW of electric power to a wide variety of spacecraft for earth orbital and interplanetary missions. The immediate design will be based upon the requirements for the Air Force SURVSATCOM mission. The proposal is presented in three volumes plus an Executive Summary. This volume describes the tasks in the technical program.

The future projected in the Project Independence Report calls heavily on nuclear energy. Validating the nuclear option will require technology improvement and implementation of new policy. But of all the issues that might compromise nuclear energy the most important now appears to be the public acceptability of this energy source.

The project is progressing under the authorizing November 12, 1973, TWX from AL to RL. It provides for removal of the retired equipment in the 234-5 Building, its packaging and burial suitable for 20-year retrieval. The building area affected will be decontaminated and made available for other purposes. Work is progressing on removal of the inspection equipment in Room 192 with two hoods having been detached from the conveyor head. No contamination exterior to the hoods has occurred. Document, Vitro-R-286 and its addendum are attached. They provide the sequence for removal of the inspection line equipment and the special procedure for removal of Hood HI-74. Twelve steel burial boxes have been received and 30 fiberglass burial boxes are in transit from Rocky Flats. No unusual problems have been encountered.

Approximately 2,000 acres of land in the center of the Hanford Reservation is contaminated with an estimated 14 Ci of /sup 137/Cs and 81 Ci of /sup 90/Sr associated with animal wastes. Approximately half of this activity is located on (or within) 2.5 centimeters of the ground surface. The source of the contamination was the B-C Cribs and trenches which were used as liquid radioactive waste disposal sites during the 1950's. The mechanism for movement of radionuclides from the disposal site to the ground surface is believed to have been burrowing by an animal (probably a badger) followed by use of the exposed material as a salt lick by rabbits and other animals. When the radioactivity was discovered, the burrow was sealed, the contaminated site was classed as a radiation zone, and surveillance initiated. The contamination site has not been a significant hazard to employees at the plant or to the public. The Atlantic Richfield Hanford Company maintained control over the surface contamination by isolation, zoning, and by continued surveillance. Methods of handling the contaminated area have been considered. Discussions of these alternatives and applicable safety analysis information are included in this document.
