Description of Change:

The proposed change is the At Risk ECRa3100-0006-07 to the )

MachineNacuum Cooling Water System. This evaluation covers the /

/

continued installation and testing of the MachineNacuum Cooling Water System as modified by ECR-3100-0006-07. This evaluation does NOT address the operation of the modified system. An additional Change Evaluation will need to be performed against the final system design prior to placing the system into operation.

ECR-3100-0006-07 addresses the reroute of sanitary water supply line and

--, sanitary drain line from constructed installation per X-3001-9571-MP to tie-in point used during previous project on X-3001 north building wall column

line 1 for sanitary water supply and to tie-in point tower cooling water return (TCWR) line between columns B2-1.6 and B2-1.

ISA Summary Addendum 1 d~scribes the HALEU MCW and VCWsystems in Section 3.9.3. Additionally, the License Application provides a description of the MCW in Section 1.1.5.6.3 and Figure 1.1-16. The final approved system design, as modified by ECR-3100-0006-07, will be required to be reviewed against these sections prior to placing the system into operation.

Any required changes to these sections will be addressed by a future change evaluation.

Reason for the Change:

Piping is required to be rerouted due to insufficient sanitary water drain capacity per original design and additional requirement for a backllow preventer on the sanitary water supply line.
