Sizewell pressuriser - a unique issue<br />
successfully resolved<br />
• Defects relate to Pressuriser heater<br />
well inserts<br />
• There are 78 heater well inserts which<br />
allow insertion of heater elements into<br />
the pressuriser<br />
• The heater well inserts are the<br />
Westinghouse Type 3 design manufactured<br />
from a single piece stainless steel forging<br />
and are of unique design<br />
• During the next outage in 2011 these<br />
heaters are expected to be replaced<br />
with a problem free design<br />
• We do not therefore expect further<br />
losses due to this issue<br />
