Chou, Rich Tuesday, December 01, 2009 9:39 AM Powell, Sid Franke, Mark; Sykes, Marvin; Morrissey, Thomas; Reyes, Rogerio; Lake, Louis; Chou, Rich; Ninh, Son FW: Monday NCRs 368472.pdf; 368282.pdf; 368351.pdf; 368389.pdf; 368470.pdf Sid:
NCR 368389 identified a crack in the containment wall inside the Intermediate Building in the area below the equipment hatch based on the Impulse Response (IR) Testing and confirmed by Core Boring. The Core Boring was in the vicinity of the highest average IR mobility value and the crack width or gap was measured at 0.009" to 0.016" which is equivalent to 1/64". Please provide the picture or drawing to show the exact location and more detail information.
As I understood when I observed the IR testing and discussed with CTL Testing Engineer, he said that the higher value of the IR is the higher or wider gap. There was a maximum gap of 2 and 1/4" identified in the Containment wall. This small gap identified might not be the real size of the gap. It is potentially that there is a bigger gap nearby and is not identified yet.

CONTAINMENT WALL ANOMALY IDENTIFIED BELOW EQUIPMENT HATCH
==
Description:==
PROCEDURE PT-407T, REACTOR BUILDING CONCRETE EXAMINATION AND TESTING, IS BEING USED TO DOCUMENT THE REACTOR BUILDING CONCRETE EXAMINATION AND TESTING IN SUPPORT OF THE EVENTS SURROUNDING THE CONCRETE DEGRADATION IDENTIFIED DURING REFUELING OUTAGE R16 (REF. NCR 358724, CR3 SGR HYDRODEMOLITION EXPOSED CRACKS).
NONDESTRUCTIVE TESTING (NDT) HAS BEEN PERFORMED INSIDE THE INTERMEDIATE BUILDING IN THE AREA BELOW THE EQUIPMENT HATCH. IMPULSE RESPONSE (IR)
TESTING INDICATED AN ANOMALY, WHICH WAS CONFIRMED BY CORE BORING A 4" DIAMETER BY 12" LONG HOLE IN THE VICINITY OF THE HIGHEST AVERAGE IR MOBILITY VALUE. EVIDENCE OF A CRACK HAS BEEN DETECTED USING A BOROSCOPE AND VISUAL INSPECTION OF THE REMOVED CONCRETE. CRACK WIDTH MEASUREMENTS OF THE CONCRETE SAMPLE HAVE BEEN MEASURED AT 0.009" TO 0.016". THERE ARE NO SIGNS OF MATERIAL DISTRESS OR DEGRADATION. THE EXPOSED SURFACES WITHIN THE CORE APPEAR TO HAVE LIGHT TO MODERATE AMOUNTS OF AGGREGATE COMPARED TO THE MAJORITY OF CORE BORE LOCATIONS. THE CRACKS DO NOT EXHIBIT CHARACTERISTICS REMOTELY SIMILAR TO THE DELAMINATION SEEN BETWEEN BUTTRESSES 3 AND 4. EXCEPT FOR THE DELAMINATED AREA, THIS IS THE ONLY LOCATION THAT A CRACK HAS BEEN DETECTED WITH IR TESTING AND CONFIRMED BY DESTRUCTIVE TESTING. THE TOTAL SURFACE AREA SCANNED WAS IN EXCESS OF 34,000 SQ. FT. INCLUDING OVER 100 CORE BORES.
