ENCLOSURE 1 NOTICE OF VIOLATION Carolina Power and Light Company Docket No. 50-261 Robinson 2 License No. DPR-23 The following violation was identified during an inspection conducted on June 24 - 28, 1985. The Severity Level was assigned in accordance with the NRC Enforcement Policy (Title 10, Code of Federal Regulations Part 2, Appendix C).
Title 10 Code of Federal Regulations, Part 50.55a(g) requires that inservice testing, to verify operational readiness of pumps and valves whose function is required for safety, be accomplished in accordance with Section XI of the ASME Boiler and Pressure Vessel (B and PV)
Code.
ASME B and PV Code,Section XI, 1977 edition through Summer 1978 addenda, has been identified as the applicable code for inservice testing.
For a pump with a vibration amplitude of.86 mils, Table IWP-3100-2 of ASME B and PV Code,Section XI, specifies the following allowable ranges of test quantities:
Acceptable Range - zero to two mils, Alert Range - two to three mils, and Required Action Range - greater than three mils. Paragraph IWP-4120 of the ASME B and PV Code,Section XI, states that "the full-scale range of each instru ment shall be three times the reference value or less".
Contrary to the above, inservice testing of pumps and valves was not accomplished in accordance with the ASME B and PV Code,Section XI, in that the following was noted:

less than or equal to five mils, Alert Range - greater than five mils, but less than six mils, and Required Action Range - equal to or greater than six mils.
Seven gauges used in CP&L Procedure Nos. OST-251, OST-403 and OST 908 had range to pressure ratios of 3.85 to 8.85.
This is a Severity Level IV violation (Supplement I).
