Illinois Power Company Docket'No. 50-461 As a result of the inspection conducted on October 20-23, 1981, and in accordance with the Interim Enforcement Policy, 45 FR 66754 (October 7, 1980), the following violation was identified:
10 CFR 50 Appendix B, Criterion III, states, in part, " Measures shall be established to assure that applicable regulatory requirements and the design basis, as defined in-50.2 and as specified in the license applica-tion...are correctly translated into specifications, drawings, procedures, and instructions."
The Illinois Power Company Quality Assurance Manual, Chapter 3 states in part that, design bases and regulatory requirements shall be adequately translated into the various design documents.
The following instances of failure to correctly translate PSAR requirements into specifications, drawings, procedures, and instructions were identified:
a.
Paragraph 8.3.1.4.2.2.3 of the Clinton Power Station PSAR states in part, "Open raceways assigned to different Divisions shall be separated by at least (a) one foot of horit:ntal free air space, (b) three feet of vertical free air space, or (c) a fire-resistant barrier with dimen-sions sufficient to maintain the minimum free air spacing of (a) and (b). This spacing shall apply if both raceways are open."
Contrary to this requirement, eight installed Class 1E cable trays were physically separated from non-Class 1E cable trays by less than the required three foot vertical separation. The licensee stated that it was the design intent to install fire protection barriers in accordance with PSAR requirements. The applicable S&L cable tray installation drawings did not specify the use of fire resistant barriers in these instances.
b.
Pa ragraph 8.3.1.4.4.3.4 of the Clinton Power Station PSAR states in part, " Instrumentation cables shall be installed in separate conduit or in separate nonventilated solid trays with covers to provide elec-tromagnetic shielding." Contrary to this requirement, two installed.
Class 1E instrumentation cable trays were of the open ladder type.
NeitL-r S&L drawings nor other documents specified the use of solid trays.
This is a Severity Level VI violation (Supplement II).
