Salem Nuclear Power Plant Proposes Approximately 200 MW Uprate: How Can Old Units Generate More Power?

For a nuclear power plant to deliver 200 MW more to the grid, construction may begin with a steam component beside the turbine. Public Service Enterprise Group (PSEG) disclosed on November 2 that the two units at the Salem Nuclear Power Plant in New Jersey are jointly proposed to add approximately 200 MW of generating capacity, of which about 112 MW would belong to PSEG. Investor materials subsequently published by the company divide the modifications across 2027 to 2029, including both an approximately 7% increase in reactor thermal power and modifications to the steam-water loop. The former figure measures the additional capacity at the grid interface, while the latter measures the change in core heat output. Only by separating these two figures can one clearly see where the additional electricity from an old nuclear...

Startup and Grid Connection Procedure for Unit 1 of the Cernavodă Nuclear Power Plant in Romania

Recently, Nuclearelectrica announced that, after meeting the minimum necessary conditions, it has initiated the procedures for reconnecting Unit 1 of the Cernavodă Nuclear Power Plant to the national power grid. This action marks a new implementation phase in the unit's return to operation; actual restoration of power supply still requires the completion of corresponding operations and compliance with nuclear safety requirements. The reconnection of a nuclear power unit to the grid is a complex operation subject to strict regulation. During the outage, the plant's professional team continued to carry out necessary work to maintain the unit in a safe state. Upon entering the grid reconnection preparation phase, all operations must still comply with applicable procedures to ensure that the return-to-service process meets nuclear safety...
