l CHANGE No. 45 TO THE TECHNICAI,SPECIFICATIONg LICENSE NO. DPR-4 CONSUMERS POWER COHPANY DOCKET NO. 50-155

1. Add a new item 3 to Paragraph 4.1.2(c) to read as follows:

"3. The high energy line sections identified in Table 9-3b shall be maintained free of visually observable through-wall leaks.

(a) If a leak is detected by the surveillance program of 4.6 k., efforts to idantify the source of the leak shall be started immediately. ,

(b) If the source of leakage cannot be identified within eight hours of detection or if the leak is found to be from a break in the sections identified in Table 9-3b, the reactor shall be in a cold abutdown within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />."

2. Change item 9.1 to read as follows:

9.1 APPLICABILITY ,

Applies to in-service structural surveillance of primary -

system components and high energy piping (outside containment).

3. Add the following item a to Paragraph 9.3 "e. The structural integrity of the high energy line sections identified in Table 9.3(b) shall be maintained at the level required by Section XI of the ASME Boiler and Pressure Vessel i u:6 , 1974, Article IWB 3000."

4. Add to 9.4 Basis the following paragraphs Intensive analysis and review has shown that there are distinct areas of concern where failure of high energy piping systems could preclude the possibility of a safe cold shutdown using safeguards equipment. t This conclusion is based on utilising the basic AEC high energy line pipe break criteria.

it therefore becomes necessary to apply additional naasures to enhance the detection of piping system weaknesses in order to mitigate the effects of a pipe rupture. The inservice examination and the frequency '

of inspection will provide a means for titxily dstection and need only be in effect until required modifications are complete.

5. Add the attached Table 9.3(b) to the end of Section 9.
