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 identify the source of the leak shall be started im:nediately.
(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 shutdown 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 folless:
9.1 APPLICABILITY Applies to in-service structural surveillance of primary system components and high energy piping (outside containment).
3.
Add the following item o to Paragraph 9.3 "e.
The structural integrity of the high energy line sect. ions identified in Table 9.3(b) shall be unintained at the level
{
required by Section XI of the ASME Boiler and Pressure Vessel ucde, 1974, Article IWB 3000."
4.
Add to 9.4 Basis the following paragraph:
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.
This conclusion is based on utilizing the basic AEC high energy line pipe break criteria.

it therefore becoms necessary to apply additional ceasures to enhance the detection of piping system weaknessos in order to nitigate the offects of a pipe rupture. The inservice encination and the frequency of inspection will provide a ueans for tinely dotection and need only be in effect until required nodifications are complete.
