Subject: CRACK IN WELD AREA OF REACTOR COOLANT SYSTEM (RCS)
Reportable Event Number: 37423

Discussion:

On October 7, 2000, Summer shut down the reactor for a scheduled
refueling outage.  During a containment inspection, a large quantity of
boron was discovered on an RCS hot leg pipe at the primary shield wall
penetration. On October 12, when investigating the source of leakage, a
dye penetrant test revealed a 4-inch long circumferential, hairline crack
in the weld between the reactor vessel nozzle and the "A" hot leg piping
(29-inch inside diameter and 2 1/2-inch nominal thickness).  The licensee
is continuing with their scheduled refueling outage activities, including
a full core offload.  The licensee is evaluating repair strategies and
available vendors to accomplish the repair which will occur prior to
reloading fuel. Additional information is available in 10 CFR 50.72
notification (Event Number 37423).


Regional Action:

Region II plans to conduct a conference call with the licensee and
appropriate NRC personnel to discuss the licensee's continuing
investigation efforts and the repair plans.  Region II plans to perform
followup inspection on this issue.
