2. Title: Waste Analysis Plan for 241-Z
The WAP was revised so the facility, process and waste descriptions would match the current authorization
basis. The WAP revision does not require a USQ evaluation or decrease the safety posture of the 241-Z facility.
All changes are within the authorization basis.

BASIS: The facility, process and waste stream descriptions in the WAP were revised to match the current state of
the PFP as described in the authorization basis (sect 126.96.36.199, 188.8.131.52, 184.108.40.206, 220.127.116.11, and associated tables and

2.Does the proposed change or occurrence represent conditions that have not been analyzed in the Authorization Basis?
 N/A [X] No  Yes/Maybe
BASIS: Sampling of the 241-Z waste tanks has been analyzed. Table 9A.4, item 4 lists possible system hazards
for "failure to collect a representative sample" and "failure to safely obtain a sample." The WAP does not alter
the plant configuration, but updates the sampling activity descriptions to match the plant configuration. This
does not affect the Authorization Basis.
.Does the proposed change represent a test or experiment NOT described in the Authorization Basis that may affect the safe operation of the
