TM I-14-022 Biennial 10 CFR 50.59 and PDMS SAR Report Page 1 of 1 TMI-2 PDMS ACTIVITIES DURING 2012 AND 2013 TMI-2 remained in a safe and stable condition during calendar years 2012 and 2013.

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

PDMS SAFETY ANALYSIS REPORT CHANGES The PDMS SAR was updated (Update 10) and submitted to the NRC in GPU Nuclear letter, TMI-13-105, dated August 23, 2013. PDMS Update 10 revised the PDMS SAR to reflect the current plant configuration, administrative processes, and editorial changes. The entire document was revised to include a complete reformatting of the PDMS SAR. All section numbers remained the same. Historical information was transferred to the back of the PDMS SAR in Appendix H, with a watermark identifying it as Historical. The only part of the document not changed were the figures that were distributed to the appropriate section or put in the same chapter in Appendix H.

PROCEDURE CHANGES The typical categories of procedures that were changed in 2012 and 2013 were administrative, ventilation, electrical distribution, rad waste processing, fire protection, 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 2012 and 2013 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 2012 and 2013.

FACILITY MODIFICATION During 2012 and 2013 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.
