ATTACHMENT 1 INSTRUCTIONS TO DETERMINE PART CLASSIFICAION FOR AQ-CLASS EQUIPMENT 2 PART LIST FORM TC 4X – 1 (Final) Appendix 4X Rev. 0 1.0 GENERAL 1.1 Scope The Scope of this Appendix is to determine the quality classification of parts used in equipment. The purpose is to utilize the classification method practically and efficiently for the receipt/storage building operation and management. 2.0 DEFINITIONS 2.1 Equipment An assembly of components designed and manufactured to perform specific functions 2.2 Component An assembly of parts to have independent function (e.g., pump, motor) 2.3 Part Minimum unit of maintenance or replacement as a basic unit of equipment or component (e.g., gasket, relay, capacitor, switch, stem) 3.0 REQUIREMENTS FOR PART CLASSIFICATION 3.1 The supplier shall identify and determine appropriate quality class of each part. Part classification depends on design function and quality class of its parent equipment. Therefore, if the quality class of equipment is AQ, the classification of the parts shall follow Section 3.2. The rest of equipment, which is considered as NQ, are not classified. All parts of NQ class equipment are also considered as quality class NQ. However, part list shall be prepared in accordance with Section 3.4. 3.2 Requirements of part classification for AQ-Class equipment 3.2.1 For the parts used in AQ-Class parent equipment (that is, augmented-quality component),

after confirming component’s regulatory requirements or special requirement imposed by the utility, parts which perform or impact to their component (equipment)’s design functions are classified as quality class AQ. 3.2.2 Suppliers shall identify the required information for all components and complete Form1 of attachment 1. 3.2.3 If the information about parent components has been changed, the supplier should be informed about Attachment 1, Form 1 from A/E. 3.2.4 Supplier shall identify and evaluate the function of each part using Form2 of attachment 1. If a part is not required for design function of parent component directly, the quality class of part is determined as NQ. 4X - 1 Appendix 4X Rev. 0 3.2.5 All parts described in the part list shall be properly designated quality class with an alpha  numeric character (AQ or NQ) and the definition is as follows: A. Augmented Quality(AQ) AQ is assigned to those parts which are provided as non-safety-related items for which regulatory requirements or special requirements imposed by the utility exist that establish design, procurement, maintenance, or quality assurance requirements. None of these requirements constitutes a safety-related functions or classification. However, because of these requirements certain items are classified as AQ in order to ensure that these requirements are preserved while operating, maintaining, or modifying the items.

B. Non-Quality(NQ) NQ is assigned to those parts that do not effect nor degrade the equipment/component safety function performance or availability. This category consists of non-safety-related items that are not subject to any special requirements.

Referring to following instructions supplier shall identify and provide the required information for all components using Form 1 of this attachment.

4X-A1-5 Appendix 4X Rev. 0 2. Instructions for Preparing Part Classification Work Sheet If the parent component is Augment-quality(AQ) the associated function of parts shall be evaluated to determine whether any special regulatory or site specific requirements apply which would require classification of the part as AQ. Referring to following instructions supplier shall identify the required information and evaluate the results for the questions using Form 2 of this attachment.
