Within the framework of the International Energy Agency, an international collaborative study on fusion radioactive waste has been initiated to examine the back end of the materials cycle as an important stage in maximizing the environmental benefits of fusion as an energy provider. The study addresses the management procedures for radioactive mate…

Lithium-lead is a candidate tritium-generating material in conceptual designs of magnetic fusion power plants. Its prolonged utilization, ultimately during the entire lifetime of such a facility, has the potential to minimize amounts of active waste and improve the economic performance. Limits to a prolonged use are production of long-lived radioac…

Modelling of temperature excursions in structures of conceptual power plants during hypothetical worst-case accidents has been performed within the European Power Plant Conceptual Study (PPCS). A new, 3D finite elements (FE) based tool, coupling the different calculations to the same tokamak geometry, has been extensively used to conduct the neutro…

Tungsten is a candidate material for a protective armour on the plasma-facing first wall of a fusion power plant. In order to assess the radiological implications of this use of tungsten, two power plant models from the European Power Plant Conceptual Study (PPCS) have been extended by the addition of a 2 mm tungsten layer on the ferriticmartensiti…

The HERCULES code was designed and developed to assist in the safety and environmental analysis tasks of the European Power Plant Conceptual Study (PPCS). However, its capabilities extend beyond this kind of analysis: coupling of the different computational tools and nuclear databases to the same geometry and material compositions, automation of in…

We present calculations of the transmutation of initially pure tungsten first-wall and divertor plasma-facing armor intoW-Re-Os alloys in the European Union Power Plant Conceptual Study (PPCS) fusion plant models A, B, and AB. The fusion neutron spectrum was modeled using the MCNP Monte Carlo code including resonance self-shielding effects, and we …
