控制鼓系统和安全棒系统是用于空间核动力装置的重要安全设备。在空间核动力装置地面工程样机的控制鼓系统和安全棒系统不仅必须满足未来在空间运行的性能要求，还须保证在设计基准地震期间和之后执行其安全功能的能力，因此必须对其抗震性能进行验证。针对此类核安全级能动设备，须从相关的法规、标准、验证方法、试验方案及验收准则各个方面考虑，明确抗震试验的试验技术要求。鼓棒系统试验样机的抗震试验研究是其模拟件通过设备抗震鉴定、产品取证制造的重要基础。 Control-drum system (CS) and safety-rod system (RS) are important safety equipments. CS and RS for nuclear ground test must meet the expected operating requirements in space applications and assure that the safety functions can perform during and after earthquake event, therefore, their seismic performances must be validated. Seismic study on CS and RS for nuclear ground test is developed to validate safety functions during and after design basis earthquake event. Test spectrum enveloping multi-support accelerations with margin, operation settings in seismic test cases and acceptance criteria are presented according to referenced regulations and standards in this paper. This seismic experiment study on CS and RS for nuclear ground test serves as an important foundation for seismic qualification and manufacture certificate application.
