Current Status of #1 - - Construction Construction Current Status of #1 The construction of Lungmen Lungmen Project has Project has The construction of almost completed. But there are still some almost completed. But there are still some deficiencies that should be improved, such as: deficiencies that should be improved, such as: The 18 construction improvement action items The 18 construction improvement action items Currently Lungmen Lungmen Project are working on the Project are working on the Currently 18 construction improvement action items to fix 18 construction improvement action items to fix the identified problems, including those of the identified problems, including those of RCCV liner, surface mounting plate, cable tray RCCV liner, surface mounting plate, cable tray seismic enhancement, and fire protection. seismic enhancement, and fire protection. 16 16

Current Status of #1 – – Testing Testing (cont.) Current Status of #1 (cont.) For verifying system function integrity and reliability, TPC promised to perform pre-op re-test for systems finishing pre- op test and approved, except ones that can’t re-build the test conditions in 2013. TPC calls senior engineers from other 3 NPPs to form the Reinforced Safety Evaluation Task Force, to perform turn- over package review, walkdown, and pre- op re-test 23 23
Current Status of #1 – – Testing Testing (cont.) Current Status of #1 (cont.) The duties of Reinforced Safety Evaluation Task Force are reviewing the system turnover package and auditing the re-test. Both of the pre-op test reports should be submitted to AEC. The first one is reference materials; the other is the formal documents. Currently, 60 pre-op re-test procedures have been fully completed. 24 24
Current Status of #1 Current Status of #1 – Improvement Action Items Improvement Action Items – The results of Post-Fukushima Safety Evaluation requires Lungmen to perform seismic and tsunami simulations, add two gas turbine generators, sea wall, and spent fuel pool instrumentation, … etc. 25 25
Fuel Loading Permit Fuel Loading Permit AEC required TPC to complete 75 tasks, including the approval of System Function Test Reports, before applying the fuel loading permit 26 26
