Local Leak Rate Testing is performed under the Option B provisions of 10CFR50 Appendix J, and the minimum LLRT leakage value used is 20 sccm based on the low end of the calibration range of the flow instrumentation.

2. 'As-Left' testing is not required if the 'As-found' leakage was acceptable and no maintenance was performed.

3. 'As-Found' testing is not required for LLRT components not on extended test intervals nor for containment penetration flanges that are simply reinstalled at the end of an outage.

TM1-14-028 Attachment 3 ATTACHMENT 3 PRESSURIZER POWER OPERATED RELIEF VALVE AND PRESSURIZER SAFETY VALVE CHALLENGES IN 2013 There were no challenges to the pressurizer power operated relief valve (PORV) o[ either of the two pressurizer (PZR) safety valves during the entire calendar year of 2013.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 2013. Therefore no challenges to the PORV or PZR safety valves occurred during 2013.

TM1-14-028 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 ol TS 3.1.4.1 were not exceeded at TMI-1 at any time during the year 2013. The figure of RCS activity for 2013 shows that the limit of 0.35 microcurie/gram dose equivalent 1-131 (DEI) was not exceeded in 2013.TMI-1 Dose Equivalent Iodine (DEI) in 2013 1.OOE+00 1.00E-01 1.OOE-02'd)0E-03 a 1 .00E-04 Il______kj.4d

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 2013.
