The objective of the Reactor Physics Quarterly Report is to inform the scientific community in a timely manner of the technical progress made on the many phases of reactor physics work within the laboratory. The report contains brief technical discussions of accomplishments in all areas where significant progress has been made during the quarter.

This report provides detailed and timely information on the results of the isotopic fuels program and related research being conducted at the Pacific Northwest Laboratory by Battelle-Northwest for the U.S. Atomic Energy Commission. This report covers the 3-month period, February through April 1970.

The discovery of a magnetic monopole would be an important experimental result. It would give a reason for the phenomenon of exact electric charge quantization that is not explained yet any other way. Schwinger's dyon theory makes monopoles even more important because they would also be the quarks, i.e., the building blocks of the hadrons. Schwinger's scheme requires the electric charge of the monopoles to be a multiple of 1/3 of the electron charge while all magnetically neutral particles must have electric charges equal to an integer times the electron charge. Monopoles would be also responsible for CP violations.

The authors propose to use the 0{sup o} neutral beam planned for Experimental Area 2 to measure differential cross sections for np elastic scattering in the diffraction region over the energy range of from 40 to 200 GeV and also total cross sections for neutrons on protons, deuterons, and other nuclei over the same energy range. The proposed experiments would use techniques previously developed by the authors in similar experiments at the Bevatron and the AGS. Most of the apparatus already exists. The two experiments could be run in the same beam, either simultaneously or sequentially. The experiments are simple and place very modest demands on accelerator performance.

This experiment will examine muon-proton inelastic scattering for virtual-photon energies of 10 to 110 GeV and for |q{sup 2}| values of 0.2 to 20.0 (GeV/c){sup 2}. The virtual-photon total cross sections {sigma}{sub t} + {epsilon}{sigma}{sub s}, or the equivalent expression in W{sub 1} and W{sub 2}, will be measured over this range of virtual-photon energies and q{sup 2} values. Some separation of {sigma}{sub T} and {sigma}{sub S}, or equivalently W{sub 1} and W{sub 2}, will be made. The multiplicity, momentum spectra and angular spectra of the charged hadrons produced in this reaction will be measured. Some channels such as {mu} + P {yields} {mu} + P + P{sup 0} will be isolated and completely analyzed. The experiment uses a hydrogen target, wire spark chambers and an analyzing magnet of conventional design.

We discuss the possibility of using synchrotron radiation to form electron rings having a very high electric field to hold the ions inside the ring. The formulas describing bow the energy and the dimension of the ring change under the effect of synchrotron radiation are derived, and a numerical example is given.

The use of Columbia River water as a reactor coolant and the subsequent discharge of this cooling water into the River introduces a number of radioactive elements into the river environment. These radionuclides are produced by the neutron activation of stable elements in solution in the cooling water and the sloughing off of radioactive corrosion products from the surfaces of the reactor cooling tubes. The relationships of these radioactive materials to river organisms have been studied since reactor operations began in 1944 (1-10). Radioanalyses in the earlier studies (3, 4), dealing mainly with seasonal variations, species differences, and geographical distribution of radioisotopes by the river biota, were confined to the measurement of total beta emitter activity and to the estimation of relative amounts of phosphorus-32 through decay curve analysis. The purpose of this study is (1) to define the interspecies and seasonal variations in the concentration of several of the more biologically important radionuclides, and (2) to update the findings of some of the earlier investigations.
