This is the more conservative position for the rod as it is one of the things that reduces fission, but it needs to be withdrawn to make power. Major Repairs are underway and the Miami herald has a story on it. Interesting stuff.....
''This is certainly not something that you see every day,'' said Roger Hannah, the Atlanta-based spokesman for the Nuclear Regulatory Commission.
Hannah said the situation started earlier this week when the nuclear operators were attempting to return Turkey Point Unit 3 to service after a routine outage for refueling.
To get the reactor functioning again, mechanisms lift from the core control rods that absorb neutrons. The rods keep the reactor dormant during the refueling.
In this case, one of the control rods ''appeared to be stuck — and could not be moved out of the reactor vessel,'' said Hanna. That meant that the reactor had to be cooled back down since it would unsafe to operate with a rod in the core.
Because this was a rare event, any attempt to remove the rod from the core fell outside the technical specifications approved by the NRC. That meant FPL had to seek a ''technical specifications amendment from the NRC,'' said Hannah.
That amendment was granted, and a power saw was used on Friday to cut the mechanism that lifts the rods and part of the rod from the rest of the rod, which remains in the core.
It remains unclear what FPL plans to do about the rod remaining in the core and whether the mechanism that lifts the rods will be need to be replaced, Hannah said." Link to Original Source top
