Dear Mr. Youngblood:

Attached are the Susquehanna SES calculations to show sufficient flow capacity for all piping and valves required in the alternate shutdown path and which show that, the pump head-flow requirements for the worst path resistances are met.

These calculations complete our action to close SER Outstanding Issue 38.

Very truly
