AI summary
- The Nova Scotia Utility And Review Board approved CI# 38724 for Nova Scotia Power Inc in the amount of $796,383, covering replacement of the secondary superheater, reheater, and boiler drain system components at Trenton Unit 5 (TRE5).
- The approved amount represents a significant reduction from the originally planned $1,549,614 capital expenditure included in the 2010 ACE Plan; the Board found the decrease justified by a reduced scope of work identified through more recent inspections, with replacement of the blowdown tank and drains deferred.
- The project originated from the 2006 Life Extension Study of Trenton Unit 5, which had recommended broader component replacements; updated inspections confirmed a narrower scope was sufficient.
- The Board had previously withheld approval via Order dated May 11, 2010, requiring NSPI to submit a separate request with appropriate justification; Information Requests issued December 21, 2010 were answered January 12, 2011 before approval was granted.
- The Board accepted the project as reasonable on the basis that the component replacements are justified for prevention of unplanned outages and were timed to coincide with a planned steam turbine outage in 2010.
