§ Mr. ShoreAlthough at present there is no commercial plant or process for the removal of krypton gas available in the United Kingdom, small-scale processes for krypton 85 extraction have been tested here, and a pilot storage plant is in operation. Plant for the extraction and retention of the small amount of krypton arising from reactors is being used in the United States, and larger-scale processes are being developed and tested in pilot reprocessing plant in several other countries. The oxide reprocessing plant (THORP) is to be designed so as to enable a krypton removal plant to be incorporated.
