Latest Patents

Among his latest patents, Zaccara's inventions include a Digital Engineered Safety Features Actuation System and a Programmable Logic Controller Seismic Support Bracket for Nuclear applications. The Digital Engineered Safety Features Actuation System is designed to establish a reliable interface between a Plant Protection System and Engineered Safety Features within a nuclear power plant. This system continuously monitors the plant protection system initiation circuit for each remotely actuated Engineered Safety Feature, allowing for prompt remedial action in response to a trip signal from the Plant Protection System. Utilizing actuation inputs from both the Plant Protection System and manual operator inputs, it controls remote equipment components such as solenoid valves, motor-operated valves, pumps, fans, and dampers.

The Programmable Logic Controller Seismic Support Bracket addresses the critical need for resilience in electrical connections during seismic and vibrational disturbances. This invention employs a bracket with two parallel side members attached to a backplane, along with a lower support bar. This structure supports the PLC modules vertically, while optional upper support bars aid in preventing any lateral movement, ensuring stability and reliability in demanding conditions.
