Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONThis specification is intended to provide the nuclear industry with a general standard for uraniumore concentrate. Material conforming to this
3、 specification will generally meet the requirements forconversion to uranium hexafluoride. However, the converter may relax or supplement this specifica-tion upon mutual agreement with the customer.1. Scope1.1 This specification covers uranium ore concentrate containing a minimum of 65 mass % uraniu
