Dear Mr. Schwencer:

In the referenced letter, PP&L agreed to performing a series of sensitivity studies to determine the appropriate plant specific'alues for the hydrodynamic mass constant (K) to b'e used in calculating the submerged structure drag loads due to LOCA steam condensation.

Based on our assessment of the results of these studies, we will be using a hydrodynamic mass constant (K) of 2 for calculating all submerged structure drag loads due to LOCA steam condensation.

The results of these studies will be formally transmitted to you in the near future.

We understand this committment will close SER Outstanding Issue 29.

Very truly yours, N.
