1. The Steamline Isolation Logic and Safety Injection Logic for this trip function may be blocked in this MODE below the P-1I (Pressurizer Pressure Interlock) Setpoint.

MODES 1, 2, 3, 4, 5 and 6.

I During fuel movement within containment or the spent fuel pool.

Trip function automatically blocked above P-1 I and may be blocked below P-l I when Safety Injection on low steam line pressure is not blocked.
