Description

The preliminary safety and operating design requirements are being defined aiming at obtaining the license for construction with a relatively large operational domain to assure an easy control and adequate availability of DEMO. The DEMO design approach is being organized, by taking into account the Nuclear Power Plant experience and the lessons learnt from ITER and GEN IV. Outstanding challenges remain in several areas with potentially large gaps beyond ITER that need to be overcome and require a pragmatic approach. Here the focus is directed mainly to evaluate and improve the readiness of technical solutions through a dedicated R&D program. Integrated Plant Design Assessments are important since the early phase to provide an integration capability of various engineering and operational options with the relevant impact on interfacing systems, e.g. primary heat transfer, electrical power supply, layout and remote maintenance. The overall DEMO plant design has to be strongly safety and operation-balance of plant oriented. The paper describes a few leading aspects of safety and balance of plant that require early attention and a continuous reanalysis at any significant design change, e.g.: (i) safety provisions required by the coolant options, including the protection and mitigation features following an in-vessel or out-of-vessel loss of coolant accident; (ii) tritium inventory limit control considering the substantial throughput of fueling; (iii) the conditions for a plasma shutdown, (iv) the pulsed operation and the relevant interfaces with the grid and with the main BoP systems; (v) the tokamak building layout that has to accommodate RM and to meet layout and environmental conditions criteria. Any effort to reduce the complexity of a Fusion Power Reactor through simplification and rationalization of the design and operation will translate into beneficial returns on safety and on operation and for a higher flexibility with respect to the integration of sub-system options.
