(1)
Degas at A.
Lower pressure ( A -* A ' ) while degassing, then return to A.
(2)
Continue design / installation of static & active systems for primary makeup / level control and secondary cooling system for S/G "B".
(3)
Reduce temperature ( A - B) by steaming on "A" S/G.
Verify operability of secondary cooling system for "B" S/G.
(4)
At B, establish solid coolino to "B" S/G, and when stable, isolate "A" S/G.
(5)
Reduce temperature ( B -+ C ) with S/G "B".
As soon as possible, start solid operation with "A" S/G, with modification pkg to be determined.
(6)
At C, trip RC Pump "A" and establish natural circulation in "A"
and "B"
loops.
W (7)
Reduce primary pressure to value to be determined (C-tD)-
(8)
Take primary system solid - activate new MU/ pressure control system.
