Follow-up Re: Follow-up Re: 1L16 Through 1L20 experiencing CRFP Oscillations
It's the dehumidifier behind Exit Stair 1.
Went out and took a look at NL2 MDP. It also powers the breaker panel inside Exit Stair 1, so I was immediately suspicious. Checked outside the building and, sure enough, there was a dehumidifier. I called the control room and got an estimate for when the oscillations would start again and stood outside by the dehumidifier for that length of time. The dehumidifier turned on and I called the control room back to confirm if the forward power oscillations started again. They had.
