This latest leak is not from a seal, but appears to be "through-wall." Entergy has reported to the Nuclear Regulatory Commission (NRC) "The leak…appears to be coming from an area of the CRD with no bolted connections. Leakage from this area is unexpected and the mechanism of failure is not understood at this time." Apparently, this leak has been occurring since Palisades' July 11 restart, after its month-long, SIRW-related shutdown. Entergy admits this current month-long leak was at a rate of 0.3 gallons per minute, but "had been recently trending upwards."
