ATTACHMENT COMMONWEALTH EDISON CO WANY RESPONSE TO NOTICE OF VIOLATION Item of Non-compliance 10 CFR 50.72 (G)(2)(ii) requires that any event that results in manual or automatic actuation of any Engineered Safety Feature, including the Reactor Protection System, be reported to NRC within four hours.
Contrary to the above, while in a Refueling Outage, Unit 2 scrammed at 1515 hrs. on March 28, 1985, and this scram was not reported to the NRC within the required time frame of four hours.
Discussion On March 28, 1985, Unit Two was shutdown for the End of Cycle Seven Refueling and Maintenance Outage. At 1515 hours0.0175 days <br />0.421 hours <br />0.0025 weeks <br />5.764575e-4 months <br /> a Reactor scram signal was initiated from a Main Steam Line High Radiation signal. An investigation revealed that the scram was caused by radiography being performed in the vicinity of the Main Steam Line Radiation detectors. The scram was considered " pre-planned" because the Shift Engineer had been given prior notification that radiography was about to be performed in the MSIV room.
On March 29, 1985, the scram of the previous day was discussed with the NRC Resident Inspector. At this time, the Resident Inspector informed the Station that a formal procedure was necessary for the scram to be considered as a " pre-planned sequence of events". The NRC must be notified within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> of any scram which is not a " pre-planned sequence".
Corrective Actions Taken and Results Achieved On March 29, 1985, at 0921 hours0.0107 days <br />0.256 hours <br />0.00152 weeks <br />3.504405e-4 months <br />, the NRC was notified using the Emergency Notification System of the scram the previous day.
Corrective Action Taken to Avoid Further Noncompliance In order to prevent reoccurrences of this type, an administrative procedure was immediately put into effect in the form of temporary piocedure 2470. This procedure has since been superceded by a permanent procedure, QAP 900-5 "In-Plant Radiography -- Required Notifications and Actions." The new procedure documents the actions to be taken by the radiographer, Shift Engineer and Radiation Protection Foreman prior to radiographic operations in the plant.
Date When Full Compliance Will be Achieved The Station is currently in full compliance.
