Science and art in heavy-ion collisions
One of the more intriguing phenomena discovered in heavy-ion physics is the seeming appearance of high energy structure in the excitation spectra of inelastically scattered heavy ions. For reasons illustrated, these may well be a phenomena unique to heavy ions and their explanation perhaps unique to TDHF.

Testing and evaluation of doubly impacted simulant-fueled Milliwatt Generator heat sources
As part of the Milliwatt Generator (MWG) Program, 12 simulant-fueled heat sources were fabricated double impact tested, and evaluated at Mound. Ten assemblies were tested at approx. 80 m/sec, and two were tested at approx. 105 m/sec. None of the strength members were breached; therefore, no fuel would have been released as a result of double impacts at the velocities and orientations tested at 450/sup 0/C. There was little difference in results for duplicate tests conducted approx. 80 and approx. 105 m/sec. Ten units contained liners that were embrittled prior to testing. This resulted in cracks in some of the liner that would not have occurred in normally fueled heat sources.

Recent US target-physics-related research in heavy-ion inertial fusion: target gains and constraints on accelerator design
Inertial-fusion targets were designed for use with heavy-ion accelerators as drivers in fusion energy power plants. In the interest of providing inputs for understanding the trade-offs among accelerator designs, an initial survey was carried out regarding target gain versus parameters of relevance. This was done in two stages, firstly target gain was related to the beam energy, power, focal radius, and ion range. Secondly, a more comprehensive discussion was made by posing target gain constraints on the beam-occupied phase-space volume of the linacs. This latter discussion had included some rather simplified models of accelerator final focus and beam transport in near-vacuum fusion reaction chambers. Some further analyses of the basic assumptions of this summary are also described.

Evolution of the tandem mirror reactor concept
We discuss the evolution of the tandem mirror reactor concept from the original conceptual reactor design (1977) through the first application of the thermal barrier concept to a reactor design (1979) to the beginning of the Mirror Advanced Reactor Study (1982).

Conceptual design study FY 1981: synfuels from fusion - using the tandem mirror reactor and a thermochemical cycle to produce hydrogen
This report represents the second year's effort of a scoping and conceptual design study being conducted for the express purpose of evaluating the engineering potential of producing hydrogen by thermochemical cycles using a tandem mirror fusion driver. The hydrogen thus produced may then be used as a feedstock to produce fuels such as methane, methanol, or gasoline. The main objective of this second year's study has been to obtain some approximate cost figures for hydrogen production through a conceptual design study.

Technical evaluation report on the proposed amendment to the technical specifications on the reactor protection system and the engineered safety features actuation system for Ft. Calhoun, Unit No. 1
This report documents the technical evaluation of the application to amend the Technical Specifications for the Ft. Calhoun Unit No. 1 Nuclear Generating Plant. The review criteria are based on the Technical Specifications of St. Lucie and Calvert Cliffs, IEEE Standards, Combustion Engineering Standard Technical Specifications, and the Code of Federal Regulations. The evaluation compares the submittal made by the licensee with the NRC staff position and the review criteria and presents the reviewer's conclusion on the acceptability of the application to amend the Technical Specifications.

Calculation of the energy-dependent efficiency of gridded /sup 3/He fast-neutron ionization chambers
Research and development activities under this contract proceeded along several lines, including development of a gas jet facility for the transport and isolation of fission product activities with half lives in the range T/sub 1/2/ less than or equal to 2 sec, studies on the factors affecting the energy and timing resolution of gridded /sup 3/He ionization detectors for delayed neutron spectroscopy and the development of simple models for calculation of the beta-decay characteristics of short-lived fission products near A = 90. Brief outlines of the activities in the areas are given. (WHK)

Nuclear waste-form risk assessment for US defense waste at Savannah River Plant. Annual report FY, 1982
A network model was developed to simulate the hydrological flow and the transport of radionuclides from a deep geological repository to the biosphere subsequent to closure. By means of very efficient computational methods for solving the fundamental differential equations, a code was developed to treat in great detail the effects of waste form characteristics and of repository designs on the repository risks. It is possible to examine near field effects heretofore not attempted. Without sacrificing the essential details of description, the code can also be applied to perform probabilistic risk analyses to high confidence levels. Analytical results showed: (1) for waste form release rates greater than approximately 5 x 10/sup -7//yr, dose to man is insensitive to release rate and release rate uncertainty; (2) significant reduction in dose can be achieved through simple design modifications; (3) a basalt repository generally does not perform as well as a salt repository; and (4) disruptive events are relatively unimportant for repository safety. 82 references.

Towards a systematic format for (seismic) equipment qualification standards
As part of technical assistance to the US Nuclear Regulatory Commission (NRC, 1), a systematic format for seismic equipment qualification (EQ) was initiated. This format consists of thirty issues associated with seismic EQ. Each issue was considered as a Category of Possible Seismic EQ Requirements and Criteria. That is, seismic EQ standards might be (but presently are not formulated in terms of requirements and criteria that address each of the thirty issues. Each of the thirty issues was ranked and a minimum set identified. The current requirements in existing NRC and national standards were also evaluated against this common set of issues, and they were estimated to score 60 out of 100 overall. It is believed that the systematic format exhibited in this paper can be of assistance in obtaining a broader and more complete perspective on seismic EQ issues. This format (but especially the technique) may also be of interest in non-seismic EQ since many of the issues are common.

Brief reconnaissance study for the addition of hydropower for Mayodan Dam, Mayodan, North Carolina
The feasibility of retrofitting the Mayodan Dam near Mayodan, North Carolina for power generation was examined. This dam, which has a developable head of 20 ft., was built in 1920 for impounding a small run-of-the-river water reservoir. The study of environmental, institutional, safety and economic factors showed that hydroelectric power development at this site appears to be economically feasible. (LCL)
