Dear Mr. Schwencer:
Attached are responses to additional questions received from the containment Engineering Branch.
Very truly yours, N.W. Curtis Vice President-Engineering and Construction-Nuclear cc:

~estion:
How will PP&L use La Salle in-plant test data to establish the local to bulk dT for Susquehanna SESS'Res ense:
The following table gives a comparison of suppression pool geometries for La Salle and Susquehanna SES:
Suppression Pool I.D.
Pedestal O.D.
Suppression Pool Volume (Normal Water Level)
La Salle 8ll 30'42,160 ft Susquehanna 88'9 I 9ll 126,980 ft3 No. of Quenchers' Pool Volume/Quencher Quencher Submergence (Normal Water Level) 18 7898".ft 21.5 ft 7936 ft 19.5 ft Height og Quencher Center-Line Above Base Mat 5 ft 3.5 ft Based on the similarity between Susquehanna and La Salle the local to bulk'bT established from La Salle inplant tests is also applicable to Susquehanna In addition, PP&L is continuing to fund the development of computer codes (like Bechtel's KFIX) for the prediction of SRV discharge induced suppression pool mixing processes.
The calculated temperature distributions will be compared to existing (CAORSO) and future (La Salle 5r.
Zimmer) in-plant test data.
Following satisfactory qualification of the computer codes they can then be used to extablish local to bulk temperature differences without test.
guesti.on:
What are the reactor pressure~
that correspond to quencher steam mass fluxes of 42 ibm/ft 's and 94 ibm/ft s?
~Res oese:
The reactor pressures are 163 psia and 369 ysia respectively.
