SUBJECT:

RELIEF FROM REQUIREMENTS OF SECTION XI-0F THE'AMERICAN SOCIETY 0F MECHANICAL ENGINEERS (ASME) BOILER AND PRESSURE VESSEL CODE-By_ letter dated October 24, 1986, you requested relief from the requirements set forth in Section XI, Rules.for Inservice Inspection of Nuclear Power Plant Components, of the ASME Boiler and Pressure Vessel Code for the Fort Calhoun Station, Unit No. 1.

In your letter, you' identified a specific ASME Code requirement that you determined to be impractical to perform and you requested relief from this requirement pursuant to 10 CFR 50.55a(g)(5)(iii).

The relief request proposes to eliminate the visual examination of the accessible areas of the reactor pressure vessel at approximately 3 year intervals.

The NRC staff has completed its review of the information you provided to sup-port your determination.

A copy of the staff's Safety Evaluation is enclosed.

Pursuant to 10 CFR 50.55a(g)(6)(i), the staff concludes that relief may be granted as requested to eliminate the VT-3 visual examination of the reactor vessel interior, except when the core support barrel is' removed, provided that you implement an alternative program consisting of performing the Examination Category B-N-1, Item ~No. B13.10 requirement each time the core support barrel is removed.

The staff has determined that this action is authorized by law and will not endanger life or property or the common defense and security and is otherwise in the public interest, giving due consideration to the. burden upon the licensee that could result if the code' requirements were imposed on the facilir.y.

Sincerely, Original sigend by:
