10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, as implemented by approved FPL Topical Quality Assurance Report TQAR 1-76A Rev. 15, TQR 5.0, Instructions, Procedures, and Drawings, and further implemented by TQAR Appendix C commitment to ANSI N18-7, 1976, paragraph 5.2.7, Maintenance and Modifications, require that maintenance or modifications which may effect functioning of safety-related structures, systems, or components shall be performed in a manner to ensure quality at least equivalent to that specified in original design bases and requirements,      materials    specifications,    and    inspection requirements.
10 CFR 50, Appendix B, Criterion VIII, Identification and Control of Materials, Parts and Components, as implemented by approved FPL Topical  Quality    Assurance  Report  1-76A,  Rev  15,  TQR  8.0, Identification and Control of Materials, Parts, and Components, requires that measures be designed to provent the use of incorrect materials, parts or components.      This is further implemented on site by procedure QI-PR/PSL-8.1, Rev 11, Identification Control of Materials, Parts, and Components.
Contrary to the above, in the two safety-related repair examples cited below, the licensee failed to control material and ensure quality at least equivalent to that specified in original design bases and requirements, materials specifications, and inspection requirements in that:
: 1. The equipment manual for the Reactor Protection System channel "C"  cabinet failed to specify approved replacement wire
)                material. As a result, on August 21, 1990, non-authorizp.
wire material was installed in the Unit 2 cabinet during the replacement of the reactor coolant pump mode selector switch.
The licensee did not establish qualification by other means.
l
: 2. On August 24,1990, a non-authorized sealant was used on a 1A Component Cooling Water (CCW) pump shaf t mechanical seal leak.
The unapproved sealant was applied to the joint after an "O" ring at the seal retaining collar was compressed, causing a minor leak at the collar-to-pump casing joint.        "O" ring replacement sculd have required partial pump disassembly.
In each instance, subsequent engineering evaluation was requested after repair completion and NRC inquiry.          These evaluations concluded that the repairs were acceptable, but this was not known at the time of the repair. The CCW system was in operation during the evaluation but the RPS channel remained out of service until authorized material was obtained and installed.

: a. Interim Measures:
Until the procedure changes can be made and training conducted              the    following      interim    measures  will  be
!                                        implemented:
(1)  The Maintenance Superintendent has issued a letter describing the requirements for material control.
All parts or material used in safety-related component repairs will be verified to conform to i
requiremente (i.e. . Technical Manuals, drawings, i
procedures,. procurement specifications, or stores material identification sheets) .                      If material can not be verified work will be stopped until a written              F.tgineering disposition is received.
(2)  These              instructions .will        be  reviewed  with  all Maintenance Personnel tg ensure compliance.
: b. Program Corrections:
1 l
(1)  The work control procedure will be revised to
!                                              provide the detail to properly implement the plant quality instructions.
(2)  Our programs to control chemicals and consumable materials                will    be    reviewed and revised as necessary.
(3)  Training . vill be held for all Maintenance Personnel on the revised material control procedures.
