Abstract

PURPOSE: To improve the seal property, by means of making the inserting property of a fuel exchanger into a good condition by forming the opening direction of packings of a V letter mark shape downwardly, and of removing adhered sodiuum by setting up a scraper at the lower part.
CONSTITUTION: A plurality of ring packings 12 are overlapped in a cylindrical flange 11 by means of arranging the opening of V letter mark downward and doubled, and are set between an upper and lower flange 11a, 17 via spacers 16 by means of allowing packing glands 14, and adapters 15a, 15b ro be interposed between the packings. This seal device is put on the casing door valve. The fuel exchanger can insert smoothly into a casing owing to the directional property of the packing 12. And the adhered sodiuum when the fuel exchanger is withdrawn from the reactor and is inserted into the casing, is dropped by a scraper 19 installed at the lower flange 11a, thereby the failure of seal property can be prevented.
