MONTICELLO NUCLEAR GENERATING PLANT 4 AWI-01.03.03 TITLE: COLOR CODED P&ID Q-LIST EXTENSION Revision 4 Page 8 of 22 5.0 FIGURES FIGURE 5.1 Color Code RED (Quality Group "A") 5.1.1 Systems and components within this quality group are part of the Reactor Coolant Pressure Boundary. This boundary extends to and includes the outermost containment isolation valve in the main steam and feedwater piping. 5.1.2 Quality Group "A" includes pressure vessels, piping, pumps and valves that are either: A. Part of the Reactor Coolant System, OR B. Connected to the Reactor Coolant System up to and including any and all of the following:

1.

The outermost containment isolation valve (in system piping that penetrates primary reactor containment).

2.

The second of two valves normally closed during normal reactor operation (in system piping that does not penetrate primary reactor containment).

3.

The Reactor Coolant System safety and relief valves. NOTE: The discharge lines of all Safety Related safety and relief valves are classified as functionally Safety Related and are color coded BROWN (see FIGURE 5.5). C. EXCEPTIONS: Certain components that are connected to the Reactor Coolant System, and therefore form part of the reactor coolant pressure boundary, may be classified as Quality Group "B" in lieu of "A" provided:

1.

In the event of postulated failure of the component during normal reactor operation, the reactor can be shut down and cooled down in an orderly manner, assuming make-up is provided by the reactor coolant make-up system (at Monticello, this is interpreted to mean 1" and smaller lines and equipment attached to these lines); OR I/djm

MONTICELLO NUCLEAR GENERATING PLANT 4 AWI-01.03.03 TITLE: COLOR CODED P&ID Q-LIST EXTENSION Revision 4 Page 9 of 22 FIGURE 5.1 Color Code RED (Quality Group "A") (Cont'd)

2.

The component is or can be isolated from the Reactor Coolant System by two valves in series (both closed, both open, or one closed and the other open). Each valve must be capable of automatic actuation and, assuming the other valve is open, its closure time must be such that, in the event of postulated failure of the component during normal reactor operation, each valve remains operable and the reactor can be shut down and cooled down in an orderly manner, assuming make-up is provided by the reactor coolant make-up system(s) only (at Monticello, this is interpreted to mean 1" and smaller lines and equipment attached to these lines). I/djm

Emergency core cooling,

2.

Post-accident containment heat removal,

3.

Post-accident containment atmosphere cleanup,

4.

Residual heat removal from the reactor and from the spent fuel storage pool (including primary and secondary cooling systems), or

5.

Spent fuel storage pool make-up water system. NOTE: Portions of these systems that are required for safety functions and that either do not operate during any normal mode of reactor operation or cannot be tested adequately, should be classified as Quality Group B". B. Cooling water and seal water systems or portions of these systems important to safety that are designed to ensure the proper functioning of other components important to safety, such as the emergency diesel generators and the control room. C. Systems or portions of systems that are connected to the reactor coolant boundary and are capable of being isolated from that boundary during all modes of normal reactor operation by two valves, each of which is normally closed or capable of automatic closure. Components in effluent lines may be classified as Quality Group "D" (see FIGURE 5.4) provided they are capable of being isolated from the reactor coolant pressure boundary by an additional valve which has a high leaktight integrity.

MONTICELLO NUCLEAR GENERATING PLANT 4 AWI-01.03.03 TITLE: COLOR CODED P&ID Q-LIST EXTENSION Revision 4 Page 12 of 22 FIGURE 5.3 Color Code GREEN (Quality Group "C") (Cont'd) D. Systems, other than radioactive waste management systems, not covered by 5.3.1.A., B., or C. above that contain or may contain radioactive material and whose postulated failure would result in conservatively calculated off-site doses (using meteorology as recommended by NRC Reg Guide 1.3) that exceed 0.5 rem to the whole body or its equivalent to any part of the body. For those items located in Seismic Category I structures, only single component failures need be assuMed. NOTE: No credit for automatic isolation from other components in the system or for treatment of released material should be taken unless the isolation or treatment capability is designed to the appropriate seismic and quality group standards and can withstand loss of off-site power and a single failure of an active component. 5.3.2 Instruments and instrument lines are classified as described in FIGURE 5.6 of this instruction. I/djm

MONTICELLO NUCLEAR GENERATING PLANT 4 AWI-01.03.03 TITLE: COLOR CODED P&ID Q-LIST EXTENSION Revision 4 Page 13 of 22 FIGURE 5.4 Color Code YELLOW (Quality Group "D") 5.4.1 Quality Group "D" includes water-and steam-containing components that are not included in Quality Groups "A", "B", or "C", but that are part of Safety Related systems or portions of Safety Related systems that contain or may contain radioactive material. 5.4.2 For sample lines connected to Safety Related systems, this Quality Group applies to: A. The portion of the sample line that is not isolated from the Safety Related system by a valve that is normally closed or is capable of automatic or remote closure. (This is classified as safety related). OR B. The portion of the sample line to and including any component that would serve to adequately restrict flow in the event of a downstream sample line break such that previously analyzed release rates are not exceeded. (This is classified as non-safety related). NOTE: The Safety Evaluation for Modification 89Z003 documents that 1/4" diameter and smaller lines provide adequate flow restriction. See the 12/18/90 QLEC minutes. 5.4.3 Instruments and instrument lines are classified as described in FIGURE 5.6 of this instruction. I/djm

MONTICELLO NUCLEAR GENERATING PLANT 4 AWI-01.03.031 TITLE: COLOR CODED P&ID Q-LIST EXTENSION Revision 4 Page 14 of 22 FIGURE 5.5 Color Codes PURPLE & BROWN (Quality Group "F") 5.5.1 Quality Group "F" consists of systems and components whose function prevents or mitigates the consequences of postulated nuclear accidents that could cause undue risk to the health and safety of the general public. 5.5.2 Two color codes have been established to identify Quality Group "F" systems and components: A. PURPLE is used to identify functionally Safety Related electrical/electronic items, and B. BROWN is used to identify other types of functionally Safety Related equipment (piping, mechanical, etc.) C. Systems or components that are Safety Related due to both pressure integrity (Quality Groups "A", 'B", "C", or "D") AND function SHALL be colored RED, BLUE, GREEN, or YELLOW (as applicable) and outlined in BROWN. 5.5.3 A series of Functional Codes has been created to further define the role of systems and components that are classified as Quality Group "F". These functional codes do not appear on the color coded P&lDs, but may occasionally be encountered in various documents (meeting minutes, memorandums, etc.) regarding the Color Coded P&ID Q-List Extension. A. The most notable Quality Group "F" systems and components and their associated functional codes are as follows: Functional Code

1.

Electrical/Electronic systems and F-1 components that:

a.

Provide an independent safety function, or

b.

In the event of failure (grounding, open circuiting, electrical shorting, or mechanical failure) could prevent a safety system from performing its intended safety function. See the electrical and instrumentation system component exclusion criteria of 4 AWI-01.03.01 (QUALITY ASSURANCE PROGRAM BOUNDARY) for further information. I/djm

b.

Instruments that monitor or control the operation of Safety Related equipment, or whose failure could cause a malfunction of the associated Safety Related equipment SHALL be classified as functionally Safety Related.

c.

Annunciators, indicators, alarms, and recorders are NOT considered Safety Related if their malfunction does not interfere with the function of Safety-Related circuitry.

d.

Instruments that are Safety Related due to their function only SHALL be colored BROWN.

e.

Instruments that are Safety Related due to both pressure integrity AND function SHALL be colored RED, BLUE, GREEN, or YELLOW (as applicable) and outlined in BROWN.

3.

Safety Related safety and relief valve F-3 discharge lines.

4.

The Quality Group designation of a component F-4 support is dependent on its relationship with its associated pressure retaining component. Hangers and component supports including non-safety related piping up to the first hanger or support beyond the associated safety-related component NOTE: Hangers and supports are not shown on Color Coded P&ID Q-List Extension drawings.

MONTICELLO NUCLEAR GENERATING PLANT 4 AWI-01.03.03 TITLE: COLOR CODED P&ID Q-LIST EXTENSION Revision 4 Page 17 of 22 FIGURE 5.6 Color Coding of Instrument Lines 5.6.1 Instrument lines connected to Safety Related systems SHALL be classified as follows: A. If the instrument line is used to actuate a safety system, the line and sensing instrumentation SHALL be of the same Quality Group Designation ("A", "B", "C", "D", or "F") as the system to which it is attached. In this situation, the sensing instrument should be either colored solid BROWN or circled in BROWN per the direction of Section 5.5.3.A.2. of this Instruction. (These instrument lines are classified as safety related). B. If the instrument line is not used to actuate a safety system, but is connected via a common header with instrumentation that is functionally Safety Related, the line and sensing instrumentation SHALL be of the same pressure integrity Quality Group Designation ("A", "B", or "C") as the system to which the header is attached. (This instrument line is classified as safety related). C. If the instrument line is not used to actuate a safety system and is not connected with functionally Safety Related instrumentation via a common header, (e.g., the instrument line is classified as non-safety related):

1.

It SHALL be of the same Quality Group Designation as the system to which it is attached from the point of connection up to and including the root valve or instrument isolation valve.

2.

MONTICELLO NUCLEAR GENERATING PLANT 4 AWI-01.03.03 TITLE: COLOR CODED P&ID Q-LIST EXTENSION Revision 4 Page 18 of 22 FIGURE 5.7 Color Code ORANGE (Special Concern) 5.7.1 As a result of Open Item No. 9 of NRC Inspection Report 50-263/87005 (Core Spray SSFI Report), NSP committed (Licensee Commitment Numbers M87028A and M87071A) to: A. Include items related to Regulatory Guide 1.97, ATWS, ASDS, High Energy Line Break and other special concern items deemed appropriate by Site Management for designation with an additional color code, B. Provide a requirement that the system engineers be consulted for non-routine maintenance, modification and procurement activities associated with these items, and C. Conduct a systematic approach to update the involved color coded P&lDs. As a result of these commitments, the ORANGE color code was established for use on the color coded P&lDs (Q-List Extension) to recognize those items of "special regulatory and/or management concern." NOTE: The CHAMPS database identifies the listing of all the "special concern codes" for equipment identified in the database. 5.7.2 If the designated equipment meets the criteria in Section 5.7.1, it will be color coded in the following manner: A. Equipment that is not Safety Related, but for which some special concern exists, should be colored solid ORANGE. B. Equipment that is Safety Related, and for which an additional special concern exists, SHALL be colored RED, BLUE, GREEN, YELLOW, BROWN or PURPLE as applicable, and should be outlined in ORANGE.
