Appendix NOTICE OF VIOLATION Illinois Power Company Docket No. 50-461 As a result of the inspection conducted on August 26 through September 27, 1985, and in accordance with the General Policy and Procedures for NRC Enforcement Actions (10 CFR Part 2, Appendix C), the following violation was identified:
10 CFR 50, Appendix B, Criterion XI, as implemented by Illinois Power's Nuclear Power Construction Quality Assurance Manual, Chapter 11, " Test Control," requires that a testing program be established to assure that all testing required to demonstrate that structures, systems and components will perform satisfactorily in service is identified and performed in accordance with written test procedures which incorporate the requirements and acceptance limits contained in applicable design documents.
Regulatory Guide 1.68, Revision 2, Apr,endix A, Paragraph 1.b(3), (committed to by the licensee in the Final Safety Analysis Report, Table 1.8-1), requires that proper mixing of solution and adequacy of the sampling system for the Standby Liquid Control System (SLCS) be demonstrated as part of the preoperational tett program.
Contrary to the above, the following example of a failure to confirm the design safety requirements of the Standby Liquid Control System (SLCS) as a result of inadequate preoperational test program implementation was identified:
The test methodology used in PTP-SC-01, " Standby Liquid Control System," to demonstrate that the Standby Liquid Control System (SLCS) boron solution storage tank air sparger would perform as designed was' inadequate in that it did not demonstrate that it was capable of mixing the boron solution after the maximum time allowed between Technical Specification (TS) surveillances (38-39 days).
In addition, it did not determine how much sparging time is required to ensure that the samples taken for the TS surveillances are representative
,
of the tank contents (461/85048-01).
'
This preoperational test has been performed (with the exception of initial fill with sodium pentaborate solution), received all required reviews and been signed-off as completed; the system has been turned over to the operations organization.
This is a Severity Level IV violation (Supplement II).
