SUBJECT:
SAFETY EVALUATION OF STEAM GENERATOR GIRTH WELD INSPECTION RESULTS ZION NUCLEAR POWER STATION, UNITS 1 AND 2 (TAC NOS. M89181 AND M89182)
Dear Mr. Farrar:
In a letter dated March 16, 1994, Commonwealth Edison Company (Comed or the licensee) reported its disposition of indications found in girth welds between the upner shell to transition cone of the steam generators of Zion Nuclear Power Station, Units 1 and 2.
Using the acceptance criteria of the ASME Code,Section XI, and fracture mechanics, the licensee dispositioned as acceptable all indications found during the dual unit outage examinations.
In letters dated May 26, 1994, and August 2,1994, the licensee submitted additional information in response to the staff's questions related to the girth weld inspections.
As stated in the attached safety evaluation, the staff concluded that the steam generators at Zion Nuclear Power Station, Units 1 and 2, are acceptable for continued service because the licensee has satisfactorily dispositioned flaws found in the upper shell to transition cone girth welds in the steam generators.
