CTS

Question 1

what is the purpose of the CTS system

Answer 1

limit containment peak pressure to less than the design pressure (12psig) during an LOCA and a SLBA.
And it removes radioactive iodine isotopes which would be released during into containment during a LOCA.

Question 2

What will auto start a CTS pump?

Answer 2

A containment phase B signal (lower containment pressure HI HI at 2.8psi on 2 of 4 channels)

Question 3

what does NaOH do for us?

Answer 3

It raises PH higher which helps keep iodine in solution.

Question 4

What is the CTS pump normal pressure and flow?

Answer 4

250psig.

3200gpm

Question 5

where is the NaOH from the spray additive tank get delivered to in the CTS system?

Answer 5

through the educator to the suction of the pump.

Question 6

what are the CTS suction sources?

Answer 6

RWST then the recirc. sump.

Question 7

what cools CTS?

Answer 7

ESW through the shell side of the HX. @3300gpm

Question 8

What signal opens the CTS valves?

Answer 8

CTS signal ( the spray add valves will close on a low low level in the spay add tank).
