ProposedAmendment No. 281 to License NPF-14 and ProposedAmendment No. 251 to License NPF-22: "ApplicationforLicenseAmendment andRelated Techlnical Specification Changes To Implement Full-Scope Alternative Source Term In Accordance with 10 CFR 50.67, " dated October 13, 2005.
The purpose of this letter is to supplement the Reference l request for an amendment to the licensing basis for the Susquehanna Steam Electric Station (SSES) Units 1 and 2 that supports a full implementation application of an Alternative Source Term (AST) methodology.
In Reference 1, PPL indicated that the Recirculation Pump Seizure Event AST Analysis would be provided as a separate document at a later date. PPL revised the Recirculation Pump Seizure Analysis and has concluded, in accordance with 10 CFR 50.59, that NRC approval is not required. Thus, a separate submittal will not be provided to NRC for the AST impacts on the Recirculation Pump Seizure Analysis.
As discussed with the SSES Project Manager on January 10, 2006, PPL identified an error subsequent to the submittal of Reference 1. The error involved incorrect transposition of calculation results in a calculation result summary table which was then also carried into results tables presented in Sections 4.6.5 and 4.6.6 of the detailed AST Safety Assessment Report (Attachment 2 of Reference 1). Attachment l to this letter contains the markup of the Reference 1, Attachment 2 affected page showing the correct values.

Document Control Desk PLA-6055  to this letter contains the revised calculation EC-RADN-1 126, Revision 1, provided to replace the Revision 0 version of the calculation originally provided in 2 of Reference 1.
If you have any questions regarding this submittal, please contact Mr. Michael H. Crowthers at (610) 774-7766.
I declare under penalty of perjury that the foregoing is true and correct.

Attachment 2 to PLA-5963 Page 49 of 60 An unidentified unfiltered inleakage rate of 500 cfm is borservatively assumed in the RADTRAD model. This inleakage bounds the tracer gas test results (including error band) from the December 2004 SSES CRHE inleakage test.
In addition, 10 cfm of unfiltered inleakage is added to the CRHE to account for ingress/egress of personnel.
4.6.4 Radiological Transport Modeling (see Figures 4 & 11)
      'The radiological release modeled in this analysis is consistent with RG 1.183.
The activity was released from the Reactor Building via the SGTS via the environment over a 2 hour period.
The 0 - 2 hour CRHE z/Q from the SGTS exhaust vent to the Control Room outside air intake of 1.45E-03 sec/in3 was used in the analysis.
4.6.5   Results - Control Room Operator Dose The RADTRAD computer code was used to determine the Control Room operator dose for the FHA/EHA events. Table 4.6-2 shows the proposed licensing basis dose limit for the FHA/EHA compared to the regulatory limit.
