On July 13, 1987, the Shearon Harris Nuclear Power Plant was operating at full power. Axial flux difference (AFD) monitoring and logging was ongoing in accordance with Technical Specifications. This logging was necessary because the automatic AFD c";.;uter alarm was not operable. At 1230, the AFD reading was missed because the operator was distracted by a power escalation after a 3S NW turbine runback. This error was discovered during the next shift's review of the logged data.
The cause of the event was personnel. error. Actions taken to prevent recurrence were (1) the operator was counseled and (2) repairs are in progress to repair the automatic AFD monitor.

Des" i tion of Event On July 13, 1987, the Shearon Harris Nuclear Power Plant was operating at full poweia The automatic axial flux difference (AFD) monitor (EIIS:ID) was not in service. At approximately 1100, a turbine runback of approximately 35 MW occurred. Around 1200, a power increase back to full power using dilution was commenced. Technical Specification 4.2.1.1.b requires monitoring and logging the indicated axial flux difference (AFD) for each operable excore channel (EIIS:IG) at least once per 30 minutes when the AFD monitor alarm is inoperable. This monitoring and logging had been ongoing, but the 1230 reading was missed by the reactor operator. The plant was operating at ap"r"ximately 99/.'ower at this time. The 1300 reading was taken. The missed reading was discovered during the back shift's review of procedur'es.
Cause The cause of the event was personnel error, an action contrary to an approved procedure. Procedure OST-1070, "AFD Monitoring and Logging," was in progress. The operator was distracted by the power escalation and missed taking the 1230 reading.
~Anal aia This event is being reported in accordance with 10CFR50.73(a)(2)(i)(B) due to a missed Technical Specification surveillance.
There are no safety consequences as a result of this event. The logged AFD before and after the missed surveillance were both -3.5. This value is well within the target band of -1.6 to -11.6. There was very little rod motion through the event and therefore no reason to assume that AFD was not
=aintained within band dur'ng "=e hour interval.
There have been no previous LERs that deal with missing this event related surveillance. Other event related surveillances have been missed in 1987 due to personnel errors', refer to LER Nos.87-015, 87-022,87-036, and 87-040.
Corrective Actions
- 1. The operator was counseled o prevent recurrence.
- 2. Repairs are in progress ior the au omatic AFD monitor.

Catawba Nuclear Station, Units 1 and 2 Docket Nos. 50-413 and 50-414 McGuire Nuclear Station, Units 1 and 2 Docket Nos. 50-369 and 50-370 Technical Specification Amendment Ice Condenser Lower Inlet Door Surveillance
Dear Sir:
By letters dated July 12, 1985, August 7, 1985, November 8, 1985, April 14, 1986, September 18, 1986 and March 16, 1987 Duke Power proposed and provided justification for an increase to the required surveillance interval for the ice condenser lower inlet doors.
During telephone conferences with members of the NRC Staff several questions were posed.
The NRC has requested a response to the following:
In the July 12, 1985 and April 14, 1986 letter to the NRC, Duke Power stated, "The doors are expected to rupture during an accident if they fail to open...". Address the possibility/probability and consequences of sump blockage due to fragments of ruptured doors and insulation.
~Res esse:
This statement assumed that an ice condenser door was incapable of opening.
Engineering judgement led to the conclusion that the door would rupture before the crane wall would.
Westinghouse conducted lower inlet door acceptance tests at 140K Design Basis Accident forces, which generated, no door missles or fragments. These tests are documented in WCAP-8110 Supplement 1 dated April 30, 1973.
g.2.:
Address long term performance of the door hinges and related hardware given the exposure to the containment and/or ice condenser atmosphere given that the surveillance interval will be lengthened.

~Res ense:
The atmosphere in the ice bed environment is at 10'P - 20'F and the absolute humidity is very low. Therefore, corrosion of uncoated carbon steel is negligible.
To ensure that corrosion is minimized while the components of the ice condenser are in operation in the Containment, components are either galvanized, painted, or placed in a protective container. Galvanizing is in accordance with ASTM, A123, or A386.
Materials such as stainless steels with low corrosion rates have been used without protective coatings.
Corrosion has been considered in the detailed design of the ice condenser components, and it has been determined that the performance characteristics of the ice condenser materials of construction are not impaired by long term exposure to the ice condenser environment.
Since metal corrosion rates are directly proportional to temperature and humidity, corrosion of ice condenser components at operating temperatures has been almost non-existent.
Based on Duke Power experience, there has not been a problematical, out of compliance condition with the lower inlet door opening tests. Our experience includes four ice condenser units, the oldest of which has been in service 10 years since initial ice load.
Based on the previously provided information and the response to the questions presented here, Duke Power believes that an extension to the lower inlet door surveillance interval is justified.
If you need further clarification or have any other questions, please advise.
Very truly yours, Hal B. Tucker RWO/101/sbn
