“…The primary objective for integrating the minimum activity blanket into the previously designed UWMAK-I magnet envelope was twofold: (1) to dernonstrate the design feasibility, and (2) to verify by calculation that the low activity is achieved. Quantitative data regarding these features of the minimum activity blanket will be discussed in following sections.…”

“…Because the reactor design is a (1) modification of a Tokamak design developed at the University of Wisconsin (UWMAK-I), a similar evaluation of that reactor was used as a point of (2) reference for the blanket integration design study. Thus, in achieving its required objective, this report includes the design integration analysis, accident analysis, and envir onmental assessment analysis for the resulting design.…”

“…Studies of solid breeding media, conducted largely at the Brookhaven National Laboratory and in Japan, have shown that adequate breeding can be obtained with a variety of materials including lithium aluminum and lithium lead alloys, Li20 and lithium aluminates and silicates (Powell et al, 1973). These systems necessarily require that the blanket be cooled by something like helium.…”

It is widely recognized that chemical engineering has important roles to play in the development of national and worldwide energy resources through optimal utilization of fossil fuel reserves. It is much less appreciated that there are crucial chemical engineering problems in the development of energy production from other sources. In particular, the successful development of nuclear fusion power generating systems will require the solution of many problems that are uniquely suited to chemical engineers.This paper presents a brief overview of the fusion development program for magnetically confined fusion power reactors and an identification of the major technological problems remaining to be solved.

“…Subsequently, it was found that other metals, such as the vanadium alloys, would have far less activation. Powell et al (1973a) are now assessing other options in structural alloys that could yield plant operation with still lower activation of the structure. This study is not yet complete, but it indicates the benefit of early analyses being used to pinpoint potential problem areas and indicate possible alternatives prior to difficult-to-change commitments in engineering development.…”

The physics problems remaining to be solved to achieve practical fusion power by magnetic confinement techniques are believed to be well posed and soluble. A programme plan recently developed in the United States calls for progressively larger plasma confinement experiments to address these physics questions in line with a serious programme in fusion power engineering. Implementation of the plan is expected to lead to the first production of power from a deuterium–tritium-fuelled system in 1980. Thereafter, three progressively larger experimental electrical power reactors are planned, leading to fusion power commercialization in the later 1990s.The environmental characteristics of fusion reactors have been estimated by analyzing conceptual reactor designs. It is projected that the only volatile radioactive material in a fusion power-plant will be the tritium fuel. Analyses indicate that tritium leakage can be held to very low levels and accordingly should not pose a significant environmental hazard.Careful selection of the materials of construction of a fusion reactor core will minimize radioactivity induced by neutron activation. This activity will be nonvolatile, and it can be isolated from the environment by the use of existing techniques. Because this induced activity is short-lived, it does not represent a long-term storage problem.Anticipated thermal efficiencies of fusion powerplants range from present-day levels (30–40%) using standard conversion systems to about 50% when more exotic techniques (such as liquid-metal topping cycles) are utilized.
