Since
1983, Tractebel Energy Engineering (TEE) has gained considerable
experience in the field of safety reassessment of NPPs. All 7 Belgian
units have already been subject to such a process carried out each
10-years of operation. TEE approach is pragmatic, cost-effective,
global and integrated.
At the end of
2000, a new important milestone has been achieved in the "Doel 1/2
second ten-yearly Safety Reassessment" project: the revision of
the Synthetic Report has been presented to the competent authorities.
Already more than half of the subjects
have been closed, which is quite a success considering the thoroughness
of the Inspection Organisation's scrutiny of this project.
The most salient event of past year
was the approval of the accident reassessments, which makes it possible
for new key parameters to be applied in core management. As a result,
core-management performance is substantially enhanced, achieving
savings of an average of four fresh fuel elements per cycle for
both units.
Other tasks carried out in the framework
of this project were related to ageing of electrical and mechanical
components, availability of safety systems, equipment qualification,
fire protection, diesel reliability, QA, operating feedback.
