Westinghouse Steam Generator Tube Mechanical Plugs (MPA X9-01) (TAC 73203, 73204) - Sequoyah Nuclear Plant, Units l'and 2" The' purpose of this letter is to clarify SQN's commitment to Item 2.d of the l
subject bulletin concerning Unit 2.
Please note that Enclosure 4 of j
Reference 1 stated that " procedures will be revised to preclude ~the installation of steam generator tubeLplugs made from Inconel 600 material."
This eliminates the use'of any plugs with the susceptible heat numbers. Your i
assumption in Reference 2 is correct, and the appropriate procedure has been revised.
