Subject:
Consequence Analysis, vent release points Message: In the ABWR consequence analysis, subsection 19E.3, a release height of 37 meters was used for all releases. This is considered a minimum height of release for the following reasons:
If the systems work as designed, any release will exit at the plant stack which is approximately 74 meters.
If the systems don't work as designed which results in an over pressure release then three things can happen:
- 1. The release still follows the HVAC path way and exits via the stack at 74 meters.
- 2. The release damages the pathway but still follows it and exits at the base of the stack at 37 meters.
- 3. The release destroys the pathway in which case one of two options are present
- a. If the release is on the refueling floor, the release exits via refueling floor blowout panels at the roof at 37 meters.

- b. If the release is in the reactor building below the level of the refueling floor, then a series of blowout panels will route the release upward to -
the main steam tunnel where a blowout panel to the tunnel will route the release to the tunnel. The release will travel down the tunnel to the turbine building interface where a blowout stack on the side of the turbine building will route the release to the top of the turbine building which is higher than 37 meters (it's something like 42 meters but I can't guarantee this number just that it is higher.)
