TMI-13-034 Attachment 1 ATTACHMENT 1 AIRCRAFT MOVEMENTS AT THE HARRISBURG INTERNATIONAL AIRPORT (HIA)

JANUARY 1, 2012 THROUGH DECEMBER 31, 2012

1. Total Aircraft Movements - 56,405
2. Estimated total number of movements of aircraft larger than 200,000 pounds -

1306.

This estimate is composed of two parts, 1056 movements of civilian aircraft, and 250 movements of U.S. Government and military aircraft.

ATTACHMENT 2 TMI-13-034 TECHNICAL SPECIFICATION 6.9.1 .B.3 PERIODIC LEAK REDUCTION PROGRAM TEST RESULTS The results of the TMI-1 2012 periodic Leak Reduction Program Tests, which included visual inspections, are summarized in Table 1.

These tests were performed in accordance with the surveillance procedures listed.

TMI-13-034 Attachment 3 ATTACHMENT 3 PRESSURIZER POWER OPERATED RELIEF VALVE AND PRESSURIZER SAFETY VALVE CHALLENGES IN 2012 There were no challenges to the pressurizer power operated relief valve (PORV) or either of the two pressurizer (PZR) safety valves during the entire calendar year of 2012.

A review of the Reactor Coolant System (RCS) pressure indication trend data concluded that the RCS pressure operated well below the PORV set point of 2450 psig, and both PZR safety valve set points of 2500 psig throughout the calendar year of 2012. Therefore no challenges to the PORV or PZR safety valves occurred during 2012.

TMI-13-034 Attachment 4 ATTACHMENT 4 RESULTS OF SPECIFIC ACTIVITY ANALYSIS-PRIMARY COOLANT SYSTEM Technical Specification 6.9.1 .B.5 requires annual reporting of certain information regarding the results of specific activity analyses in which the primary coolant exceeded the limits of Technical Specification (TS) 3.1.4.1. The limits of TS 3.1.4.1 were not exceeded at TMI-1 at any time during the year 2012. The figure of RCS activity for 2012 shows that the limit of 0.35 microcurie/gram dose equivalent 1-131 (DEI) was not exceeded in 2012.

TMI-1 Dose Equivalent Iodine (DE) in 2012 1.OOE+00 1.OOE-01 91.OOE-02 -+DEI

TMI-1 3-034 Attachment 5 ATTACHMENT 5 MAJOR CHANGES TO RAD WASTE TREATMENT SYSTEMS Technical Specification Section 6.17 requires reporting of Major changes to Radioactive Waste Treatment Systems. Major changes are interpreted to mean changes that would alter how the system functions or changes that would affect operational exposures, offsite dose rates or integrated doses. There were no major changes to the liquid, gaseous, or solid radioactive waste treatment systems at TMI-1 during the year of 2012.
