When is Tref and Program Tavg equal?

A

100% RTP

Program Tavg is linear when going from 0% to 100% and Tref is not.

  • Note:*
  • Rod motion can occur in as little as 0.3 ˚F temperature mismatch.*

When should the a condensate pump and a FW booster pump be secured?

A

≈ 40% Rx Power

17
Q

    • *

When should zinc injection be secured?

A
  • After Rx Trip:*
  • *As soon as practical**
  • Planned Rx Shutdown:*
  • *At least 1 day prior**

For a power reduction of > 72 hrs, may reduce zinc injection.

Note:
If CVCS demin taken offline for > 2 hrs or letdown flow is changed by > 20%, then zinc injection should be evaluated by chemistry.
