Embodiments are directed to fault-tolerant power-distribution modules (PDM). A PDM is included in a power plant to provide a portion of the power generated by the plant as a direct current (DC) signal for the operation of the plant. A power-distribution system distributes a portion of the power generated by the plant to one or more PDMs, as an alternating current (AC) signal. The PDMs provide electrical power to various plant loads. The plant loads may be related to the safety of the operation of the power plant. At least one of the plant loads is a non-safety related load. A PDM may be a DC power supply. The power plant may include one or more power-generating module (PGM) assemblies. At least one of the PGM assemblies may include a nuclear reactor. Accordingly, the power plant may be a modular nuclear power plant.
