BIENNIAL 10 CFR 50.59 AND PDMS SAR REPORT Attached is the biennial report for Three Mile Island Nuclear Station, Unit 2 (TMI-2) for years 2008 and 2009. This report is being submitted in accordance with TMI-2 Technical Specification 6.8.1.4 and the requirements of 10 CFR 50.59.

TMI-10-010 Biennial 10 CFR 50.59 and PDMS SAR Report Page 1 of 2 TMI-2 PDMS ACTIVITIES DURING 2008 AND 2009 TMI-2 remained in a safe and stable condition during calendar years 2008 and 2009.

Activities included rad waste processing, routine surveillances, equipment repair, and structural repairs.

PDMS SAFETY ANALYSIS REPORT CHANGES The PDMS SAR was updated (Update 8) and submitted to the NRC in GPU Nuclear letter, TMI-09-090, dated August 24, 2009. PDMS Update 8 revises the PDMS SAR to reflect the current plant configuration and administrative processes, and to make some editorial changes.

PROCEDURE CHANGES The typical categories of procedures that were changed in 2008 and 2009 were administrative, ventilation, electrical distribution, rad waste processing, fire protection, compressed air, and Technical Specification surveillance. All procedure changes at TMI-2 are made using the Exelon 10 CFR 50.59 Review Process, which provides a screening process to determine if the change requires a written evaluation. During 2008 and 2009 there were no procedure changes which required a written evaluation.

TESTS AND EXPERIMENTS No tests or experiments not described in the PDMS SAR were performed at TMI-2 during 2008 and 2009.

TMI-10-010 Biennial 10 CFR 50.59 and PDMS SAR Report Page 2 of 2 FACILITY MODIFICATION During 2008 and 2009 there were no facility modifications that impacted the PDMS SAR, thus there were no 10 CFR 50.59 evaluations performed with regard to facility modifications. Due to the non-operating and defueled status of TMI-2 during PDMS, there are no structures, systems, or components that are required to meet the safety-related criteria. Therefore, there are no structures, systems, or components classified as safety-related at TMI-2 during PDMS. All facility modifications are made using the Exelon 10 CFR 50.59 Review Process, which provides a screening process to determine if the change requires a written evaluation. This screening process is based on, and incorporates in its entirety, the implementation guidance provided in NEI 96-07, Revision 1.
