摘要： PURPOSE:To hold a nuclear reactor in an excellent operation state by providing an auxiliary cooling panel consisting of plural cooling pipes between a furnace pressure container and a cooling panel and adjusting the number of cooling pipes where cooling water runs according to the operation state of the nuclear reactor. CONSTITUTION:When the reactor is put in normal operation, the temperature of the auxiliary cooling panel 11 is controlled by sending water to a limited number of cooling pipes 10 and a heat removal quantity matching the operation state of the nuclear reactor is selected to maintain the panel at proper temperature. In case of a nuclear reactor forcible cooling loss accident, all inlet valves 17 - 21 and all outlet valves 22 - 26 of the auxiliary cooling panel 11 are opened to send cooling water into the cooling pipes 10 in all sections. Consequently, sufficient cooling performance is displayed and a temperature rise due to the decay heat of the nuclear reactor pressure container 3 and core 1 can be suppressed low.

摘要： PURPOSE:To remove heat at a small quantity during ordinary operation and at the increased quantity at the time of a loss of force cooling power by disposing auxiliary cooling panels between a reactor pressure vessel nd cooling panels and arbitrarily adjusting the temp. thereof. CONSTITUTION:The auxiliary cooling panels 8 which allow temp. control are installed between the reactor pressure vessel 1 and the cooling panels 2 and the temp. of the auxiliary cooling panels 8 is adjusted arbitrarily. The quantity of the heat removed from the reactor pressure vessel 1 can be adjusted as desired in this way during the ordinary operation. The temp. of the auxiliary cooling panels 8 is lowered down to about the temp. of the cooling panels 2, by which the reactor pressure vessel 1 and a reactor core 4 can be cooled in the event of the loss of the force circulating and cooling power for the reactor. The radiation heat released from the reactor pressure vessel is efficiently absorbed in this way and the temp. rise of the reactor is prevented.

摘要： PURPOSE:To enable the decrease of operators' exposure by radioactive contamination and the effective utilization of iodine adsorbents and to simplify a device by remotely controlling sepn. valves and discharging the used adsorbents by the gravity fall of the adsorbents. CONSTITUTION:A process gas flows from a process piping 10 into the lower part of a lower filter container 1b where the greater part of the iodine is adsorbed by the adsorbents 4. The gas emitted from the container 1b flows through a process piping 11 into the lower part of an upper filter container 1a where the iodine remaining in the gas is adsorbed; thereafter, the gas flows through a process piping 12 to a down stream system. The deterioration of the adsorbents 4 progresses from a lower side in such a manner. Since the outlet apertures of the piping 10 and the piping 11 are disposed to face the lower side with respect to the inlet part of the respective filter containers 1a, 1b, the clogging of the adsorbents 3, 4 in the pipings is prevented. Furthermore, the deteriorated adsorbents dropped by gravity and are housed through a screw feeder 9 into a drum 13 when the sepn. valves 7d and 7e on the container 1b side are opened.
