Appendix D to Part 52-- Design Certification Rule for the AP1000 DesignI. Introduction Appendix D constitutes the standard design certification for the AP1000 1 design, in accordance with 10 CFR part 52, subpart B. The applicant for certification of the AP1000 design is Westinghouse Electric Company LLC. II. Definitions A. Generic design control document
(generic DCD) means the document
containing the Tier 1 and Tier 2 information B. Generic technical specifications means the information required by 10 CFR 50.36 and 50.36a for the portion of the plant that is within the scope of this appendix. C. Plant-specific DCD means the document maintained by an applicant or licensee who references this appendix consisting of the information in the generic DCD as modified and supplemented by the plant-specific departures and exemptions made under Section VIII of this appendix. D. Tier 1 means the portion of the design-related information contained in the generic DCD that is approved and certified by this appendix (Tier 1 information). The design descriptions, interface requirements, and site parameters are derived from Tier 2 information. Tier 1 information includes: 1. Definitions and general provisions; 2. Design descriptions; 3. Inspections, tests, analyses, and acceptance criteria (ITAAC); 4. Significant site parameters; and 5. Significant interface requirements. E. Tier 2 means the portion of the design-related information contained in the generic DCD that is approved but not certified by this appendix (Tier 2 information). Compliance with Tier 2 is required, but generic changes to and plant-specific departures from Tier 2 are governed by Section VIII of this appendix. Compliance with Tier 2 provides a sufficient, but not the only acceptable, method for complying with Tier 1.Compliance methods differing from Tier 2 must satisfy the change process in Section VIII of this appendix. Regardless of these differences, an applicant or licensee must meet the requirement in Section III.B of this appendix to reference Tier 2 when referencing Tier 1. Tier 2 information includes: 1. Information required by §§ 52.47(a) and 52.47(c), with the exception of generic technical specifications and conceptual design information; 2. Supporting information on the inspections, tests, and analyses that will be performed to demonstrate that the acceptance criteria in the ITAAC have been met; and 3. Combined license (COL) action items (COL license information), which identify certain matters that must be addressed in the site-specific portion of the final safety analysis report (FSAR) by an applicant who references this appendix. These items constitute information requirements but are not the only acceptable set of information in the FSAR. An applicant may depart from or omit these items, provided that the departure or omission is identified and justified in the FSAR. After issuance of a construction permit or COL, these items are not requirements for the licensee unless such items are restated in the FSAR. 4. The investment protection short-term availability controls in Section 16.3 of the DCD. F. Tier 2* means the portion of the Tier 2 information, designated as such in the generic DCD, which is subject to the change process in Section VIII.B.6 of this appendix. This designation expires for some Tier 2* information under paragraph VIII.B.6. G. Departure from a method of evaluation described in the plant-specific DCD used in establishing the design bases or in the safety analyses means: 1. Changing any of the elements of the method described in the plant-specific DCD unless the results of the analysis are conservative or essentially the same; or 2. Changing from a method described in the plant-specific DCD to another method unless that method has been approved by the NRC for the intended application. H. All other terms in this appendix have the meaning set out in 10 CFR 50.2, or 52.1, or Section 11 of the Atomic Energy Act of 1954, as amended, as applicable. III. Scope and Contents A. Tier 1, Tier 2 (including the investment
protection short-term availability controls in
Section 16.3), and the generic TS in the
AP1000 DCD (Revision 15, dated December
8, 2005) are approved for incorporation by
reference by the Director of the Office of the
Federal Register on February 27, 2006, under
5 U.S.C. 552(a) and 1 CFR part 51. Copies of
the generic DCD may be obtained from
Ronald P. Vijuk, Manager, Passive Plant
Engineering, Westinghouse Electric B. An applicant or licensee referencing this
appendix, in accordance with Section IV of
this appendix, shall incorporate by reference
and comply with the requirements of this
appendix, including Tier 1, Tier 2 (including
the investment protection short-term
availability controls in Section 16.3 of the
DCD), and the generic TS except as otherwise C. If there is a conflict between Tier 1 and Tier 2 of the DCD, then Tier 1 controls. D. If there is a conflict between the generic DCD and either the application for design certification of the AP1000 design or NUREG–1793, "Final Safety Evaluation Report Related to Certification of the AP1000 Standard Design," (FSER) and Supplement No. 1, then the generic DCD controls. E. Design activities for structures, systems, and components that are wholly outside the scope of this appendix may be performed using site characteristics, provided the design activities do not affect the DCD or conflict with the interface requirements. IV. Additional Requirements and Restrictions A. An applicant for a combined license
that wishes to reference this appendix shall,
in addition to complying with the 1. Incorporate by reference, as part of its application, this appendix. 2. Include, as part of its application: a. A plant-specific DCD containing the same type of information and using the same organization and numbering as the generic DCD for the AP1000 design, as modified and supplemented by the applicant's exemptions and departures; b. The reports on departures from and updates to the plant-specific DCD required by paragraph X.B of this appendix; c. Plant-specific TS, consisting of the generic and site-specific TS that are required by 10 CFR 50.36 and 50.36a; d. Information demonstrating compliance with the site parameters and interface requirements; e. Information that addresses the COL action items; and f. Information required by 10 CFR 52.47(a) that is not within the scope of this appendix. 3. Include, in the plant-specific DCD, the proprietary information and safeguards information referenced in the AP1000 DCD. B.

compliance with the Commission's
regulations applicable and in effect at the b. Special circumstances as defined in 10 CFR 50.12(a) are present. 4. An applicant or licensee who references
this appendix may request an exemption
from Tier 2 information. The Commission
may grant such a request only if it determines
that the exemption will comply with the
requirements of 10 CFR 50.12(a). The
Commission will deny a request for an
exemption from Tier 2, if it finds that the
design change will result in a significant
decrease in the level of safety otherwise
provided by the design. The grant of an
exemption to an applicant must be subject to
litigation in the same manner as other issues
material to the license hearing. The grant of 5.a. An applicant or licensee who
references this appendix may depart from
Tier 2 information, without prior NRC b. A proposed departure from Tier 2, other than one affecting resolution of a severe accident issue identified in the plant-specific DCD, requires a license amendment if it would: (1) Result in more than a minimal increase in the frequency of occurrence of an accident previously evaluated in the plant-specific DCD; (2) Result in more than a minimal increase
in the likelihood of occurrence of a
malfunction of a structure, system, or (3) Result in more than a minimal increase
in the consequences of an accident
previously evaluated in the plant-specific (4) Result in more than a minimal increase in the consequences of a malfunction of an SSC important to safety previously evaluated in the plant-specific DCD; (5) Create a possibility for an accident of a different type than any evaluated previously in the plant-specific DCD; (6) Create a possibility for a malfunction of an SSC important to safety with a different result than any evaluated previously in the plant-specific DCD; (7) Result in a design basis limit for a fission product barrier as described in the plant-specific DCD being exceeded or altered; or (8) Result in a departure from a method of evaluation described in the plant-specific DCD used in establishing the design bases or in the safety analyses. c. A proposed departure from Tier 2
affecting resolution of an ex-vessel severe
accident design feature identified in the (1) There is a substantial increase in the probability of an ex-vessel severe accident such that a particular ex-vessel severe accident previously reviewed and determined to be not credible could become credible; or (2) There is a substantial increase in the consequences to the public of a particular exvessel severe accident previously reviewed. d. If a departure requires a license amendment under paragraph B.5.b or B.5.c of this section, it is governed by 10 CFR 50.90. e. A departure from Tier 2 information that is made under paragraph B.5 of this section does not require an exemption from this appendix. f. A party to an adjudicatory proceeding for
either the issuance, amendment, or renewal
of a license or for operation under 10 CFR 52.103(a), who believes that an applicant or
licensee who references this appendix has
not complied with paragraph VIII.B.5 of this
appendix when departing from Tier 2
information, may petition to admit into the 6.a. An applicant who references this
appendix may not depart from Tier 2*
information, which is designated with b. A licensee who references this appendix may not depart from the following Tier 2* matters without prior NRC approval. A request for a departure will be treated as a request for a license amendment under 10 CFR 50.90. (1) Maximum fuel rod average burn-up. (2) Fuel principal design requirements.

(14) Containment vessel design parameters. d. Departures from Tier 2* information that are made under paragraph B.6 of this section do not require an exemption from this appendix. C. Operational requirements. 1. Generic changes to generic TS and other operational requirements that were completely reviewed and approved in the design certification rulemaking and do not require a change to a design feature in the generic DCD are governed by the requirements in 10 CFR 50.109. Generic changes that require a change to a design feature in the generic DCD are governed by the requirements in paragraphs A or B of this section. 2. Generic changes to generic TS and other operational requirements are applicable to all applicants who reference this appendix, except those for which the change has been rendered technically irrelevant by action taken under paragraphs C.3 or C.4 of this section. 3. The Commission may require plant-specific
departures on generic TS and other
operational requirements that were 4. An applicant who references this appendix may request an exemption from the generic technical specifications or other operational requirements. The Commission may grant such a request only if it determines that the exemption will comply with the requirements of 10 CFR 52.7. The grant of an exemption must be subject to litigation in the same manner as other issues material to the license hearing. 5. A party to an adjudicatory proceeding
for either the issuance, amendment, or
renewal of a license, or for operation under
10 CFR 52.103(a), who believes that an
operational requirement approved in the
DCD or a TS derived from the generic TS
must be changed may petition to admit such
a contention into the proceeding. The
petition must comply with the general
requirements of 10 CFR 2.309 and must
demonstrate why special circumstances as
defined in 10 CFR 2.335 are present, or
demonstrate compliance with the
Commission's regulations in effect at the time
this appendix was approved, as set forth in
Section V of this appendix. Any other party
may file a response to the petition. If, on the 6. After issuance of a license, the generic TS have no further effect on the plant-specific TS. Changes to the plant-specific TS will be treated as license amendments under 10 CFR 50.90. IX. Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC) A.1. An applicant or licensee who
references this appendix shall perform and
demonstrate conformance with the ITAAC 2. The licensee who references this
appendix shall notify the NRC that the
required inspections, tests, and analyses in 3. If an activity is subject to an ITAAC and
the applicant or licensee who references this
appendix has not demonstrated that the
ITAAC has been met, the applicant or
licensee may either take corrective actions to
successfully complete that ITAAC, request an
exemption from the ITAAC under Section
VIII of this appendix and 10 CFR 52.97(b), or B.1. The NRC shall ensure that the required
inspections, tests, and analyses in the ITAAC
are performed. The NRC shall verify that the
inspections, tests, and analyses referenced by
the licensee have been successfully
completed and, based solely thereon, find
that the prescribed acceptance criteria have
been met. At appropriate intervals during 2. In accordance with 10 CFR 52.103(g), the Commission shall find that the acceptance criteria in the ITAAC for the license are met before fuel load. 3. After the Commission has made the finding required by 10 CFR 52.103(g), the ITAAC do not, by virtue of their inclusion within the DCD, constitute regulatory requirements either for licensees or for renewal of the license; except for specific ITAAC, which are the subject of a § 52.103(a) hearing, their expiration will occur upon final Commission action in such a proceeding. However, subsequent modifications must comply with the Tier 1 and Tier 2 design descriptions in the plantspecific DCD unless the licensee has complied with the applicable requirements of 10 CFR 52.98 and Section VIII of this appendix. X. Records and Reporting A. Records 1. The applicant for this appendix shall maintain a copy of the generic DCD that includes all generic changes to Tier 1, Tier 2, and the generic TS and other operational requirements. The applicant shall maintain the proprietary and safeguards information referenced in the generic DCD for the period that this appendix may be referenced, as specified in Section VII of this appendix. 2. An applicant or licensee who references
this appendix shall maintain the plant-specific
DCD to accurately reflect both 3. An applicant or licensee who references this appendix shall prepare and maintain written evaluations which provide the bases for the determinations required by Section VIII of this appendix. These evaluations must be retained throughout the period of application and for the term of the license (including any period of renewal). B. Reporting 1. An applicant or licensee who references this appendix shall submit a report to the NRC containing a brief description of any plant-specific departures from the DCD, including a summary of the evaluation of each. This report must be filed in accordance with the filing requirements applicable to reports in 10 CFR 52.3. 2. An applicant or licensee who references
this appendix shall submit updates to its
DCD, which reflect the generic changes to
and plant-specific departures from the
generic DCD made under Section VIII of this
appendix. These updates must be filed under
the filing requirements applicable to final
safety analysis report updates in 10 CFR 52.3 3. The reports and updates required by paragraphs X.B.1 and X.B.2 must be submitted as follows: a. On the date that an application for a
license referencing this appendix is
submitted, the application must include the b. During the interval from the date of application for a license to the date the Commission makes its findings required by 10 CFR 52.103(g), the report must be submitted semi-annually. Updates to the plant-specific DCD must be submitted annually and may be submitted along with amendments to the application. c.
