A microreactor system that can mix fluids at precise timing has two inlets into which fluids are introduced and merges, in a channel, a first fluid introduced from a first inlet and a second fluid introduced from a second inlet, a first pump that sends the first fluid toward the inlets, and a second pump that sends the second fluid toward the inlets, a first fluid detector that detects an arrival of the first fluid at the first inlet, and a second fluid detector that detects an arrival of the second fluid at the second inlet.

Microreactor system

In mixing of raw materials having different flow rate ratios (volume ratios) (different flow rates), in order to achieve a good mixing effect, the present invention includes: for raw materials having different flow rates, a high-flow-rate side flow path () through which a raw material on a high-flow-rate side flows; a low-flow-rate side flow path () through which a raw material on a low-flow-rate side flows; branch flow paths () which are branched from the high-flow-rate side flow path; and a residence flow path () which is a flow path after the branch flow paths () and the low-flow-rate side flow path () merge. The branch flow path () and the branch flow path () merge in a way of sandwiching the low-flow-rate side flow path ().

Neutron shielding materials and a cask for spent fuel

A dry radioactive substance storage facility stores spent fuel assemblies from nuclear power plants. The facility comprises a structure having a storage room storing storage tubes containing spent fuel assemblies. An air inlet duct defining an air inlet passage through which air is supplied into the storage room and a stack defining an air discharge passage through which air from the storage room is discharged outside are connected to the storage room. Radiation shielding members are disposed on the side of the air inlet duct and on the side of the stack, respectively, in the storage room to intercept radiation propagating toward the air inlet passage and the air discharge passage.
