[

In addition to the examinations required by Technical Specification 3/4.0.5, the following inspections will be performed to detect evidence of leakage at. Unit 1 Pressurizer' Vessel Heater Sleeves (120) and Pressurizer Vessel Instrument Nozzles (7):

y.

1..

During each reactor shutdown where HOT STANDBY (MODE 3) condition is reached and a COLD SHUTDOWN (MODE 5) duration of 7 or more days is not anticipated, a visual exam (as described in ASME XI IWA-2212) shall be performed to detect evidence of leakage. The exam shall be performed' from a location that will directly view the visible portion of g
