Installation of a Diverse Shutdown System (DSS) at INPP Unit 2
Description
The year 2005 was extremely important in the history of the operation of Ignalina NPP as two sufficiently redundant protection systems independent of each other and based on different principles ensured the safety of its single operational Unit (No. 2). After a detailed analysis of safety justification documents, permission was given in October 2004 for starting trial commercial operation of emergency protection sets 1 and 2, as well as the fast power reduction system.In order to ensure additional protection against common cause failures, 49 new design actuators (servo drives)1 for reactor control rods of emergency protection and fast power reduction system are to be installed at INPP Unit 2 in 2006. In all, there are 211 control rods in the reactor. After installation of the new servo drives, the recommendation regarding introduction of a DSS in reactors of RBMK type given in the safety analysis for INPP Unit 1 of 1997 will be implemented.
