摘要

It is acknowledged that Accelerator Driven System(ADS)offers interesting transmutation possibilities.The accelerator and reactor combination can be used for spent fuel transmutation utilizing high energy neutrons in reactor core.Zero-power facilities are constructed for ADS design and operational verification.During earthquake,the localized stress of mechanical structures will increase due to vibration,which is a risk for structural integrity.The detailed seismic analysis is needed for stress assessment in earthquake conditions.Three-dimensional finite element model of the ADS zero-power facilities is constructed to perform dynamic evaluation using ABAQUS/standard code.The Square Root of Square Sum(SRSS)calculation method is chosen to combine modals in response spectrum analysis.The first principal stress of vessels and bolt strength are evaluated.Both water zero-power reactor core and lead reactor core vessels meet ASME-III-ND specification.
