TMI-09-013 Attachment 1 ATTACHMENT 1 AIRCRAFT MOVEMENTS AT THE HARRISBURG INTERNATIONAL AIRPORT (HIA)

JANUARY 1, 2008 THROUGH DECEMBER 31, 2008

1. Total Aircraft Movements - 66,961.

2. Estimated total number of movements of aircraft larger than 200,000 pounds -

1309.

This estimate is composed of two parts, 1284 movements of civilian aircraft, and 25 movements of military aircraft.

TMI-09-013 Attachment 2 ATTACHMENT 2 TECHNICAL SPECIFICATION 6.9.1.B.3 PERIODIC LEAK REDUCTION PROGRAM TEST RESULTS The results of the TMI-1 2008 periodic Leak Reduction Program Tests, which included visual inspections, are summarized in Table 1. These tests were performed in accordance with the referenced procedures. (See Note 1 for procedure titles.)

TMI-09-013 Attachment 3 ATTACHMENT 3 PRESSURIZER POWER OPERATED RELIEF VALVE AND PRESSURIZER SAFETY VALVE CHALLENGES IN 2008 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 2008.

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 2008. Therefore no challenges to the PORV or PZR safety valves occurred during 2008.

TMI-09-013 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 2008. The figure of RCS activity for 2008 shows that the limit of 0.35 microcurie/gram dose equivalent.l-131 (DEI) was not exceeded in 2008.

TMI-09-013 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 2008.
