Dear Mr. Vassallo:
In a telephone conversation with your staff on May 15, 1984, Carolina Power &

Specifically, historical calibration data for the new Brunswick-1 containment hydrogen and oxygen monitors was requested for the purpose of determining instrument setpoint stability (i.e., long-term drift). Attached is CP&L's response to this request. Should you have any further questions, please contact Mr. John S. Dietrich at (919) 836-6154.
