Division Spotlight
Nuclear Installations Safety
Devoted specifically to the safety of nuclear installations and the health and safety of the public, this division seeks a better understanding of the role of safety in the design, construction and operation of nuclear installation facilities. The division also promotes engineering and scientific technology advancement associated with the safety of such facilities.

The JT-60SA project
JT-60SA (Japan Torus-60 Super Advanced) is the world’s largest superconducting tokamak device. Its goal is the earlier realization of fusion energy (see Fig. 1). Fusion is the energy that powers the Sun, and just 1 gram of deuterium-tritium (D-T) fuel produces enormous energy—the equivalent of 8 tons of crude oil.
Last fall, the JT-60SA project announced an important milestone: the achievement of the tokamak’s first plasma. This article describes the objectives of the JT-60SA project, achievements in the operation campaign for the first plasma, and next steps.

The long-term (>1000 years) hazard of radioactive waste emplaced in a geologic repository could be reduced by separating the most significant long-lived radionuclides and transmitting them to stable products by bombardment with neutrons in power reactors. A cost-risk-benefit analysis of this concept shows that, while it is technically feasible to partition and transmute the principal long-lived constituents, there are no cost-risk-benefit incentives that can be identified. The cost of partitioning and transmuting the actinide elements is estimated to be $9.2 million/ GW(electric). yr [1.28 mill/kWh(electric)]. The shortterm radiological risk is increased by 0.003 health-effect/GW(electric). yr, and the expected long-term benefit (i.e., incremental risk reduction from a repository) is 0.06 health-effect/GW(electric ).yr integrated over 1 million years. The latter is only ∼0.001% of the health effects expected from natural background radiation and is equivalent to $32 400 per person-rem saved. If nonradio logical risks are included, the short-term risk actually exceeds the long-term benefits.
