a x ENCLOSURE 1 NOTICE OF VIOLATION Tennessee Valley Authority Docket Nos. 50-327 and 50-328 Sequoyah License Nos. DPR-77 and DPR-79 The .following violation was identified during an inspection conducted on December 6, 1985 - January 5, 1986. The Severity Level was assigned in accordance with the NRC Enforcement Policy (10 CFR Part 2, Appendix C).

Technical Specification 6.8.1 requires that written procedures be established, implemented, and maintained covering safety-related activities stated in Appendix A of Regulatory Guide 1.33, Revision 2.

a. Work Plan (WP) 11850 was established to implement a' modification to the Essential Raw Cooling Water System (ERCW) including the installation of check valves 2-VLV-67-786A, -786B, -786C, and -7860. The WP required the disassembly of the check valves in accordance with MI 11.4,

-Maintenance of CSSC Valves.

Contrary to the above, the WP was not adequately implemented in that the disassembly of valves 2-VLV-67-786A and -786C was not documented in accordance with MI 11.4.

b. Radiological Control Instruction RCI-14, Radiation Work Permit (RWP)

Program, was established to implement requirements for entry or work in an area of known or potential radiological hazard including the requirements for anti-contamination clothing. RWP 02-0-86668, which was written in accordance with this program, required workers entering the area near the boric acid transfer pump for removal of water on the floor to wear a top and bottom plastic suit.

Contrary to the above, two workers who entered the area on RWP 02-0-86668 did not implement the procedure in that they had unfastened

~

the top front ~ portion of the plastic suit, thereby increasing the potential for skin contamination. The workers' actions were being observed by their foreman at the time.

c. Maintenance Request (MR) A593499 was established, in part, to replace a NAMCO limit switch on the Unit 2 number 3 steam generator blowdown isolation valve. Maintenance Instruction (MI) 10.37, NAMCO Limit Switches, was prescribed by MR A593499 and implemented during the NAMCO limit switch replacement. MI 10.37 step 5.2 prescribed the use of Measuring and Test Equipment (M&TE), specifically a 0-30 inch r ound torque screwdriver.

Contrary to the above, the torque svewdriver used to accomplish step l- 6.1.1.2 was not a 0-30 inch pound torque screwdriver, and a "non-l intent" change to.MI 10.37 was not made per Administrative Instruction

'AI-4 to reflect as such.
