26 Fracture Tughness fr Pressure Tubes CNSC Regulatry Oversight (3/3) During Part 1 Hearing, the Cmmissin requested CNSC staff t strengthen the licence cnditin n fracture tughness mdel fr HEQ in excess f 120 ppm: Updated: Befre hydrgen equivalent cncentratins exceed 120 ppm, the licensee shall demnstrate that pressure tube fracture tughness will be sufficient fr safe peratin beynd 120 ppm. Cmpliance verificatin criteria fr the Licence Cnditin are defined in the Licence Cnditins Handbk CNSC staff will reprt t the Cmmissin n status f the pressure tubes thrugh the annual Regulatry Oversight Reprt (ROR) fr Canadian Nuclear Pwer Generating Sites Bruce Pwer will nt be allwed t perate beynd 120 ppm HEQ until the fracture tughness mdels have been accepted by CNSC staff nuclearsafety.gc.ca 26

27 Fracture Tughness fr Pressure Tubes CNSC staff recmmendatin CNSC staff recmmend that the Cmmissin apprve peratin up t a maximum f 300,000 EFPH and add a new Licence Cnditin n HEQ in excess n 120 ppm Staff recmmendatin is based n: 1. Adequate safety margins will always be maintained 2. Strng knwledge f degradatin mechanisms f pressure tubes 3. Bruce Pwer has an effective pressure tube inspectin and mnitring prgram 4.
