onductor,” should include the stranding configuration (i.e., round, compressed or compact). (3) Clauses 6.2.1.8 and 6.2.2.6, “Identification,” should include the date of applicable manufacturing standards and the date of manufacture. (4) Clause 6.4.4 (b) should be supplemented with the following: “The qualification type tests for coaxial, triaxial and twinaxial cables should include sufficient testing of cable’s critical electrical performance characteristics to permit an adequate analysis of the compatibility of the coaxial, triaxial and twinaxial cables for the specific application, as appropriate.” (5) Clause 9.1, “General,” should be supplemented to include the following: “Documentation should also include manufacturer’s inspection and maintenance requirements.” (6) Programs for monitoring of environmental conditions (such as temperature, radiation levels), and condition monitoring should be implemented for safety-related power, instrumentation, and control cables. Condition monitoring programs may include any appropriate technique(s), supplemented with walkdowns to look for visible signs of anomalies attributable to aging with particular emphasis on the identification of localized adverse environments or “hot spots.” For safety-related power cables that are inaccessible or installed underground, appropriate inspection, testing and monitoring programs should be implemented to detect degradation. The condition monitoring and its frequency may be adjusted based on the cable performance. IEEE Standard 383-2003 references several industry codes and standards. If a referenced code or standard has been separately incorporated into the regulations, licensees and applicants must comply with RG 1.211, Page 4 the standard as set forth in the regulations. By contrast, if the NRC staff has endorsed a referenced standard in a regulatory guide, that standard constitutes an acceptable method of meeting a regulatory requirement as described in the
