This request is being made for the third ten-year interval at Catawba Unit 2. The third ten-year interval began on October 15, 2005 for Unit 2 but the pressure tests in question are not required until the third period of the third ten-year interval, which begins on October 15, 2012.
The Catawba Unit 2 inservice inspection plans for the third ten-year interval will be developed according to the 1998 Edition with 2000 Addenda.
This Code Edition and Addenda erroneously lists two pressure test requirements for Class 3 systems.

Duke Energy Corporation plans to comply with the pressure and temperature hold times cited in 10 CFR 50.55a(b)(2)(xx) which requires a ten-minute holding time after attaining test pressure for Class 2 and Class 3 components that do not normally operate during operation, and no holding time is required for the remaining Class 2 and Class 3 components provided that the system has been in operation for at least four hours for insulated components or ten minutes for uninsulated components.
As noted in RIS 2004-12, licensees seeking to use later editions and addenda of the ASME Code,Section XI, pursuant to 10 CFR 50.55a(f) (4) (iv) or 10 CFR 50.55a(g)(4) (iv), are not required to seek relief pursuant to 10 CFR 50.55a(a)(3), 10 CFR 50.55a(f)(5)(iv), or 10 CFR 50.55a(g)(5)(iv).
