A. Purpose This procedure provides actions to continue plant cooldown and depressurization to cold shutdown, with no accident in progress, under conditions that allow for the potential formation of a void in the upper head region with a vessel level system available to monitor void growth.
B. Symptoms or Entry Conditions I. This procedure is entered after completing the first ten steps of FNP-2-ESP-O.2 when the limits of FNP-2-ESP-O.2 must be exceeded; from the following:
- a. FNP-2-ESP-O.2, NATURAL CIRCULATION COOLDOWN TO PREVENT REACTOR VESSEL HEAD STEAM VOIDING, step 11
- b. FNP-2-ESP-O.2, NATURAL CIRCULATION COOLDOWN TO PREVENT REACTOR VESSEL HEAD STEAM VOIDING, step 14 Page 1 of 16
