Filed: 1992-08-20
Abstract: PURPOSE:To effectively utilize NOX in a reprocessing by using NOX on nitrous acid generated in the dissolution reaction for spent fuel or radiolysis reaction of nitric acid for controlling the valence of the dissolved material in nitric acid solution in the reprocessing. CONSTITUTION:In the NOX generation process 1 in a reprocessing nitrous acid is produced due to the dissolution reaction of nitric acid 2. It eventually becomes to NOX and moves to gas phase gas 6. It is transported as it is or after being purified by eliminating the co-existing matter included in it with a co-existing matter eliminating device 5 or being purified to some extent, to a valence control process 3 in the reprocessing process as NOX gas 7. In the process 3, by bowing in NOX, the valence state of solved material in the nitric acid 4 is converted into the state proportional to the electric potential of NOX. Thus, by transporting the NOX generated in the process 1 to process 3, the dissolved material in the process 3 is oxidized or reduced.

Abstract: PURPOSE:To prevent a hit to be caused when a speaking (transmitting) channel is switched to another channel by constituting a system which can communicate in parallel the same communication content by using a plural channels of plural base radio stations and mobile radio equipment. CONSTITUTION:When an S/N monitoring section 22 detects that the quality of the channel CH1 being used between a base radio station 30-1 and mobile ratio equipment drops from a level L1, the section 22 instructs the mobile radio equipment through the channel CH1 to make preparatory works for receiving radio waves from another base radio station 30-n through another channel CHn in parallel with the radio waves from the station 30-1. As a result, communication is started between the base radio station 30-n and mobile radio equipment through the channel CHn. When a radio system controller 20 confirms the channel CHn and that the quality of the channel CHn is above a fixed level L2, the controller 20 releases the channel CH1. Therefore, the communication with the mobile radio equipment can be continued without occurrence of hit.
