A feasibility study for the construction and operation of an experimental facility devoted to the simulation of the Decay Heat Removal System (DHRS) of the Advanced Lead Fast Reactor European Demonstrator (ALFRED) is developed with reference to the DHRS concept proposed by Ansaldo Nucleare, including a steam generator, an in-pool condenser (Isolation Condenser), a non-condensable gas tank, a steam and a feed water line each equipped with isolation valves. A preliminary design of the experimental plant is developed with the aim to use existing SIET facilities/infrastructures as much as possible. The main considered facilities/infrastructures are as follows: technological hall with the existing SPES-3 support frame 30 m high equipped with a suitable crane and elevator; an existing pool already installed at the requested elevation; the IETI facility with power supply and control room; auxiliary systems; an on-site calibration laboratory for the instrumentation; an on-site workshop for all the needed mechanical works. Taking into account both technical feasibility and budget constraints two different options are considered for the scaling factor of the facility. A scaling factor 16:6 is assumed for the basic design while a scaling factor 16:2 is considered for possible cost reduction. The technical feasibility of the test facility has to be checked for both the above mentioned options. The outcomes of the study are: design criteria, detailed description and drawings of the facility main components, information about the foreseen instrumentation as well as the operation basics. Time schedule and budget estimate, including the facility design, realization and operation are provided for both the facility scaling options.

Abstract

A feasibility study for the construction and operation of an experimental facility devoted to the simulation of the Decay Heat Removal System (DHRS) of the Advanced Lead Fast Reactor European Demonstrator (ALFRED) is developed with reference to the DHRS concept proposed by Ansaldo Nucleare, including a steam generator, an in-pool condenser (Isolation Condenser), a non-condensable gas tank, a steam and a feed water line each equipped with isolation valves. A preliminary design of the experimental plant is developed with the aim to use existing SIET facilities/infrastructures as much as possible. The main considered facilities/infrastructures are as follows: technological hall with the existing SPES-3 support frame 30 m high equipped with a suitable crane and elevator; an existing pool already installed at the requested elevation; the IETI facility with power supply and control room; auxiliary systems; an on-site calibration laboratory for the instrumentation; an on-site workshop for all the needed mechanical works. Taking into account both technical feasibility and budget constraints two different options are considered for the scaling factor of the facility. A scaling factor 16:6 is assumed for the basic design while a scaling factor 16:2 is considered for possible cost reduction. The technical feasibility of the test facility has to be checked for both the above mentioned options. The outcomes of the study are: design criteria, detailed description and drawings of the facility main components, information about the foreseen instrumentation as well as the operation basics. Time schedule and budget estimate, including the facility design, realization and operation are provided for both the facility scaling options.
