==SUBJECT:==
GENERIC LETTER 95-03, "CIRCUMFERENTIAL CRACKING OF STEAM GENERATOR TUBES," COMPLETION OF LICENSING ACTION (TAC NO. M92273)
 
==Dear Mr. Feigenbaum:==
On April 28, 1995, the U.S. Nuclear Regulatory Commission (NRC) issued Generic Letter (GL) 95-03, "Circamferential Cracking of Steam Generator Tubes," to all holders of operating licenses or construction permits for pressurized-water reactors. The NRC issued GL 95-03 for three principal reasons:
i (1)
Notify addressees about the safety significance of the w.ent steam generator tube inspection findings at Maine Yankee Atomic Power Station, (2)
Request that all addressees implement the actions described within the generic letter, and (3)
Require that all addressees submit to the hRC a written response regarding implementation of the requested actions.
In addition, GL 95-03 alerted addressees to the importance of performing comprehensive examinations of steam generator tubes using techniques and equipment capable of reliably detecting the types of degradation to which the steam generator tubes could be susceptible. The staff also noted that the performance of steam generator tube examinations is controlled, in part, by Appendix B to Title 10 Part 50, of the Code of federal Regularfons (10 CFR Part 50).
In GL 95-03, the NRC staff tb o requested that licensees take the following actions:
(1)
Evaluate recent operating experience with respect to the detection and 4
sizing of circumferential indications to determine the applicability to gl" their plants, (2)
On the basis of the evaluation in Item (1) above, as well as past 0
inspection scope and results, susceptibility to circumferential I
cracking, threshold of detection, expected or inferred crack growth rates, and other relevant factors, develop a saie g assessment justifying continued operation until the next scheduled steam generator tube inspections, 9708130355 970807 PDR ADOCK 05000443 RBC ME CENTER COPY lillillIquilJIUllllilli

Mr. Ted C..Feigenbaum 1 (3)
Develop plans for the next-steam generator tube inspections as they pertain to the detection of circumferential cracking. The inspection plans should address, but not be limited to, scope (including sample expansion criteria, if applicable), methods, equipment, and criteria (including personnel training and qualification).
To document the outcome of these actions, the NRC staff requested that addressees prepare and submit:
-(1).
A safety assessment justifying continued operation, predicated on the evaluation performed in accordance with requested actions 1 and 2 (above),and (2)
A summary of the inspection plans developed in accordance with requested action 3 (above) and a schedule for the next planned inspection.
Mr. John Opeka's {{letter dated|date=June 27, 1995|text=letter dated June 27, 1995}}, and your {{letter dated|date=October 23, 1995|text=letter dated October 23, 1995}}, provided the information requested by GL 95-03, and therefore TAC No.
M92273 is closed.
For your information, the staff's findings regarding this issue are contained in NUREG-1604, "Circumferential Cracking of Steam-Generator Tubes."
