Attention all employees!

(Important information regarding THE 2Ind reduced inventory - orange path.)

An orange path, for the key safety functions of core cooling and inventory, will be entered on Sunday, May 23, when the reactor vessel level is lowered below 55% (defined as reduced inventory or midloop) to approximately 3/4 pipe level. The Reactor Coolant System (RCS) will be drained to 3/4 pipe to facilitate installation and removal of Steam Generator (S/G) nozzle dams.

Draining the RCS to reduced inventory/midloop places the plant in a vulnerable configuration. The plant is vulnerable because there is less water in the RCS, which significantly reduces the time required to reach boiling temperatures.

Although the Outage Safety, Outage Planning processes, and Operating Procedures are designed to minimize the risk of a malfunction or error while the plant is in this configuration, it is important to minimize the time that the .plant is in reduced inventory/midloop.

What can you do to help? Don't rush. Instead, work efficiently and plan ahead to minimize the time the plant is drained to inventory/midloop. Do the job right the first time.

Attention all employees!

An orange path, for the key safety functions of core cooling and inventory, will be entered on Thursday, April 8, when the reactor vessel level is lowered below 55% (defined as reduced inventory or midloop) to approximately 3/4 pipe level. The Reactor Coolant System (RCS) will be drained to /4pipe to facilitate installation and removal of Steam Generator (S/G) nozzle dams. The nozzle dam installation will allow S/G tube inspections to take place during fuel motion.
