For antidetonation constraint, it is located at the correct position of CRDM stroke housing, with the DRPI connecting plate groups on stroke housing
Into CRDM lateral supports.The supporting structure is connected with shroud component, and seismic (seismal is delivered to pressure vessel from drive mechanism
On top cover.
The antidetonation supporting structure disposed inboard of the system have between more DRPI plates, each DRPI plates exist it is certain between
There is also gap between gap, and DRPI plates and the supporting of CRDM antidetonations.In the case of being accumulated in gap larger position can be produced at the top of CRDM
Move, cause root to produce larger stress.Meanwhile, larger collision load can be also produced between DRPI plates under earthquake operating mode
Lotus.
Relevant design unit once used the design side that the DRPI plates that fritter is replaced with the big anti-seismic plate of monoblock are combined
The problem of formula is to reduce CRDM penetration pieces root and impact load.In this design, the overall position under earthquake operating mode at the top of CRDM
Move smaller, the collisionless load and impact load of anti-seismic plate and the quake-proof supporting structure on IHP is also smaller between DRPI plates.
But the design of this monoblock anti-seismic plate will greatly reduce the flexibility of CRDM replacings.
In a kind of patent " presurized water reactor CRDM tabular antidetonation ring " (application number：201220702271.8) in,
Utility model a kind of CRDM tabular antidetonation ring, the seismic support for CRDM.Needed to ensure to install, it is adjacent
Still there is larger gap between tabular antidetonation ring, the tabular antidetonation ring can not still solve the problems, such as the gap accumulation between each CRDM.
