Abstract: Vertical motion of nuclear reactor fuel element bundles is limited by tubular pistons which engage fuel assembly upper end fittings to thereby urge the fuel assemblies in the vertically downward direction. The tubular pistons are provided with mechanical stop means to limit their vertical motion and are disposed within guide tubes which extend between the reactor core fuel alignment plate and upper guide structure.

Abstract: A safeguard system for a nuclear power plant is disclosed that incorporates means for containing the effects of a reactor accident to protect the environs of the plant against the release of harmful contaminants. The system includes particular containment structure housing the plant and a vapor suppression pool for condensing vaporous elements released from the plant. Various core cooling apparatus are integrated into the system to provide immediate and long term cooling of the reactor following a serious accident.
