Recently, the Special Committee for Earthquake Resistant Reactor hasdiscussed on the earthquake hazard and aseismic design of a British type NuclearPower Station to be built in Japan. The aseismic design proposed at the Committeeby author is reported in this paper. As the structural parts of the reactor insidethe biological shielding structure-graphite pile, diagrid and pressure vessel etc.-where the post-operation repair work is not feasible, should be designed safelyagainst every possible damage due to the large displacement and acceleration ofthe earthquake, it is most desirable that these parts are not accelerated and de-formed by the destructive earthquake.Then the reactor is to be designed to have the low pass filter vibrating systemwith the nonlinear elasticity. That is to say, in details, the diagrid of the reactoris connected with the biological shielding concrete wall by the flexible steel wireropes and is placed on the concrete basement by the supporting columns that havehinged joints at each end. These wire ropes and columns are respectively designedas to safely resist the horizontal and vertical components of the seismic accelera-tion. Especially in Chapter 4, the low pass filter system of the reactor is analyzedand several numerical examples of it are calculated.
