Licensee/Facility: Notification:
Tennessee Valley Authority MR Number: H-00-0076
Sequoyah 2 Date: 12/13/00
Soddy-Daisy,Tennessee
Dockets: 50-328
PWR/W-4-LP
Subject: Fuel Assembly Leakage at Sequoyah
Discussion:
The Tennessee Valley Authority (TVA) determined, during the Sequoyah Unit
2 October 2000 refueling outage, that one fuel rod in one of four lead
test assemblies (LTAs) containing fuel pellets made with blended-down
highly enriched uranium (HEU) had been leaking during the last operating
cycle. The LTAs were manufactured by Framatome Cogema Fuels (FCF) as part
of a Department of Energy (DOE)-sponsored program to use HEU as fuel in
one or more of the TVA nuclear reactors. There are 264 fuel rods in each
of the four LTAs, or 1056 rods total.
The LTAs had been in the core since the last refueling outage in April
1999 and had burnup of approximately 24,000 mwd/mtu. TVA discovered the
leakage while conducting In-Mast fuel assembly sipping during core
off-load activities. The licensee sipped all 193 fuel assemblies and also
found a non-HEU fuel assembly, manufactured by Westinghouse, that had
several leaking rods. The Westinghouse assembly had been in the reactor
core for three operating cycles. The licensee removed the leaking LTA
from the core, as well as the other three assemblies.
FCF performed ultrasonic testing on the LTAs to determine the extent of
the problem and determined that only a single fuel rod in the LTA had
been leaking. FCF was unable to observe the defect using fiber optic
visual inspection. They did observe, however, that the defective fuel rod
had elongated by about 0.5 inch. FCF also performed high magnification
visual testing to look for other indications of possible failure
mechanisms such as bad welds, presence of foreign material, or other
manufacturing defects. FCF is presently reviewing the LTA manufacturing
records for evidence of a possible manufacturing error. Both TVA and FCF
are in the process of attempting to determine the root cause of the
defect and FCF will publish a report by the end of January 2001 with the
results of its root cause analysis. Currently, TVA sees no correlation
between the subject rod developing a leak and the fact that the rod
contains HEU.
The staff has preliminarily concluded that there is no safety issue
related to this failure. During the operating cycle, reactor coolant
system radioactivity level remained below 50 percent of the Sequoyah
Technical Specification limit for Dose Equivalent Iodine-131, which is
0.35 microcuries per gram. TVA believes that this rod failure will have
no long-term programmatic effect on the DOE plan to use HEU as reactor
fuel in one or more TVA reactors, which may start as early as 2005.
