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

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.

• A two-step licensing review process is adopted for nuclear plant in Taiwan.
• For Lungmen Project, a construction permit was issued following a preliminary safety analysis report (PSAR) being satisfactorily reviewed in March 1999.
• AEC started the construction inspection, including resident inspection, after issuing construction permit.

• Taipower Company submitted first version of FSAR in August 2007 for AEC’s review.
• After over 3 years of review, AEC is currently preparing a draft safety evaluation report (SER).
• AEC will conduct readiness inspections for Lungmen plant to confirm the FSAR commitment before issuing fuel loading permit.

• As plant operators play a key role in their dynamic responses to normal operations and anomalies, their qualification and ability are among the main themes for nuclear safety.
• Plant operators and senior operators are required to pass stringent tests, including written examination, plant walk-through and simulator operation, before they are allowed to work at the main control room of the plant.
