1.0 PURPOSE AND SCOPE The purpose of this procedure is to establish and maintain an effective plant component labeling program. This procedure outlines responsibilities and requirements for a labeling program that provides clear, permanent, and consistent identification of plant components. Labels should provide operators and maintenance personnel with sufficient information to help ensure positive identification. Since experience indicates that labels will be lost, removed, or misplaced during plant operation, a strong commitment to labeling must be maintained.

This procedure does not address building and facility general labels such as FIRE DOOR labels and EXIT signs.

This procedure is supplemental to the plant design documents and is not intended to replace those designations.

1. Supply component description for EDBS.
2. Revi'ew equipment tagging sheets for concurrence with recommended tag numbers.

3.3 Quality Assurance Unit

1. Verify the correctness of each tag.

3.4 Harris Plant En ineerin Section t

1. Update SFD's in a timely manner to incorporate Operations tag numbers.

2~ Issue Instrumen't Details showing tubing configuration and instrument valves.

3. Update Construction Control System with EDB nomenclature and Operations tag numbers.

4 ' DEFINITIONS/ABBREVIATIONS HPES- Harris Plant Engineering Section HPOS Harris Plant Operations Section QA/QC- Quality Assurance/Quality Control EDBS Equipment Data Base System HPCS- Harris Plant Construction Section 5 ' GENERAL 5.1 General Practice 5.1 '1 Labels shall be positioned so they are readily visible and, wherever possible, in a horizontal position. Large equipment, e.g. st'earn generators, feedwater heaters and tanks, may be labeled in multiple locations, and stencilled when .possible.

5 ~ 1'2-"","- Labels shall be attached in a manner that eliminates any possible confusion as to the item being identified.

Labels shall not obscure other items nearby.

513" Colored labels (when used) shall provide high contrast between characters and background to ensure legibility.

5.1.4 Labels shall be permanently attached and designed to withstand wear and erosion.

PLP-610 Rev. 1 Page 4 of 9

Osl e 5.1 Ceneral Practice (Cont'd) 515 ~ Label content shall be defined in EDB. The Operations tag numbers and descriptions shall be compatible with identifying information found on system valve lineup sheets, plant piping and instrument drawings (Flow Diagrams) or Simplified Flow Diagrams, and plant procedures.

5.1.6 Abbreviations shall be plant-specific, and understood by plant personnel.

5.1.7 Background colors used in color coding labels shall be assigned only one meaning per color or color combination and shall be consistent with the requirements of FSAR Section 8.3.1.3 ~

5.1.8 Labels and their attaching devices shall be of limited halogen c'ontent when directly attached to stainless steel piping or components. See ANSI N45.2.1 for limits.

5 '.9 Label material should be plastic for tags on electrical switchboards'lastj.c or stainless tags may be used on electrical panels and instrumentation racks'tainless should be used for all other component labels.

Non-stainless steel components inside containment should be stencilled when possible to eliminate the possibility of labels becoming irradiated and/or contaminated, plugging strainers and drains, or entering pump suctions.

CAUTION:

Special care must be taken for tags within containment. Inside containment only qualified coatings and materials are allowed.

Contact'EMC to,determine if..4 material is acceptable for use insi'de".,containment. An exadple of a problem material would be" the use;.'of';,'a1'uminum tags inside containment. The amount of aluminum inside,'.containment. is limited to meet design basis accident scenar'ios. 'Adding aluminum tags would violate this basis. The same is true of certain types of paint and coatings.

The valve tag number format consists of unit, system designation and number, e.g. 1SM-120, where 1 denotes unit 1, SM denotes Service Mater System and 120 denotes denotes valve number. See PLP-610 Rev 1 Page 5 of 9

OS1 Table 1 for approved system designations. The tag format for Butterfly Valves and Dampers in HVAC systems should consist of the Ebasco tag numbers.

Plant valves should be tagged regardless of function or proximity to other equipment. The valve tag should be an embossed stainless steel tag and include valve tag number and valve nomenclature.

The tag may also include the EDB identifiers, or an Ebasco tag number for information only.

Valve tags shall be. attached securely. However, valve tags should remain visible and should not interfere with maintenance or valve operation.

S.3 Instrument & Instrument Valve Ta in The instrument tag number shall be listed in the instrument list. Instrument tags that provide visual operator information should include the tag number and instrument description. Other instruments shall only be tagged with the instrument number. The instrument tag shall be attached to the instrument rack or hung on the instrument. Instruments on Control Panels shall be tagged as appropriate for the panels The instrument valve tag number format consists of the instrument root valve tag number, a descriptive suffix and a number (when necessary), e.g. 1SW-61-HV1, where 1SW-61 denotes the root valve number. See Table 2 for approved descriptive suffixes. For instruments that do not have a root valve, the instrument valve format should consist of the instrument number and descriptive suffix and number as indicated above. The instrument and instrument valve tags will be an embossed, stainless steel tag, and will contain the respectiver tag number except as noted above.

'Pags shall be attached securely and shall not interfere with instrument visibility or valve operation.

5.4 E ui ent Ta in

/

Equipment may include, but not be limited to, pumps, tanks, heat exchangers', fan units, etc. The format for equipment tag numbers should "consist of unit, system designation, E for equipment, and an identifying number, e.g. 1SW-8009, where 1 denotes unit, SW denotes Service Water System and 8009 denotes the equipment identifier. Major equipment defined by Operations Unit may be assigned a tag number consisting of unit, system designation, and the mnemonics derived from the equipment nomenclature, e.g. 1CE-CBPA, where 1 denotes the unit, CE denotes Condensate System and CBPA denotes Condensate Booster Pump A.

PLP-610 Rev. 1 Page 6 of 9

OS1 5.4 E ui ment Ta in (Cont'd)

A stainless steel tag should be embossed with the equipment tag number and EDB description, and securely attached to the equipment. Whenever possible, equipment tag numbers and descriptions 'should also be stencilled on the equipment using paint that has been "approved for contact with stainless steel or reactor coolant".

6.0 IMPLEMENTATION Valve tags shall be hung after systems are released for test to the Startup Group in accordance with the Startup Manual.

Tags may be hung by Operations or Technical Support.

Instrument tags shall be hung, if required, after systems are released for test to the Startup Group.

Tags may be hung by Operations, Technical Support or Maintenance, (Maintenance will label relays and fuses).

6.4 E ui ment Ta in Equipment tagging or stenciling shall be performed after systems are released for test,to the Startup Group.

Tags may be hung by Operations, Maintenance or Technical Support.
