  • 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.

  • 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.
