Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?

This paper considers the issues of safety assessment of new nuclear power plant (NPP) projects with VVER Generation III+ reactors in relation to the probability target for large release, which is subject to verification in the development of a full-scale Probabilistic Safety Assessment (PSA) Level 2. The design solutions implemented in Generation III+ reactors allow reducing the probability of a severe accident (SA) due to internal initial events to a level of 10−7/year. Exceeding the radioactive release criterion may thus be related mainly to the consequences of beyond-design external events. This places special demands both for the selection of SA scenarios to consider and the methods for modeling the accident progression and consequences. The paper presents a method for selecting the representative SAs in the frame of PSA of new VVER NPP projects and a practical example of radiological analysis for two bounding accidents at an arbitrary NPP using an advanced integrated computer code system.
