シールプラグ装置。This is a lower seal plug device for a pressure pipe that constitutes a nuclear reactor core, and includes a sealing element and a latch mechanism for a primary coolant that is inserted and locked into a pressure pipe while supporting a connecting body between a fuel body and a lower jacket plug. A pressure tube-shaped atom is characterized in that an independent fuel drop prevention plug, which is arranged in series with a seal plug provided with the seal plug and is provided with a latch mechanism at the bottom of the seal plug, is inserted and locked into the lower open end of the pressure tube. Furnace bottom seal plug device.
