NUCLEAR COMPATIBILITY CERTIFICATION OF NUCLEAR WEAPON SYSTEMS, SUBSYSTEMS AND SUPPORT EQUIPMENT
|Publication Date:||11 January 2017|
General. This document outlines the specific tasks, analyses, and tests that are necessary to assure nuclear compatibility between nuclear mission stores and nuclear combat delivery weapon systems (excluding nuclear facilities). Specific requirements to ensure compatibility are under the purview of interface control documents and interface specifications and must take into consideration the Stockpile-to-Target Sequence. Nuclear weapon system compatibility certification authority is derived from Air Force Instruction (AFI) 63-125, Nuclear Certification Program.
a. The Air Force Nuclear Certification Process is described in detail in AFI 63-125. Major elements of nuclear certification are: design certification and operational certification. Components of design certification are: compatibility certification, nuclear safety design certification, safety rules development, and technical order certification. Although all components of design certification are closely related and arguably difficult to totally separate, this document will focus on nuclear compatibility certification. The Master Nuclear Certification List (MNCL) is the sole authority for determining equipment certification status and is managed by the AFNWC's certification management organization.
b. Nuclear Weapon System Compatibility is the capability of two or more nuclear weapon system components of equipment or materiel to exist or function in the same system or environment without mutual interference. Nuclear weapon system compatibility evaluations are a component of Operational Suitability as established in AFI 63-101/20-101. Release of the Nuclear Compatibility Certification Statement (NCCS) constitutes nuclear compatibility certification of the delivery system with the specific weapon indicated. Release of a Statement of Compatibility (SOC) letter by Sandia National Laboratory (SNL) documents the nuclear weapon system is compatible with a specific weapon. SNL will then publish an Aircraft Compatibility Control Drawing (ACCD) for nuclear gravity weapons and/or Compatibility Certification (CC) drawing for air launched missile warheads once compatibility certification activities have been completed.
c. Nuclear safety design certification requirements are closely related to compatibility requirements. They are described in detail in Air Force Manual (AFMAN) 91-118, Safety Design and Evaluation Criteria for Nuclear Weapon Systems, and AFMAN 91-119, Safety Design and Evaluation Criteria for Nuclear Weapon Systems Software, and are not repeated here. Once a Nuclear Safety Analysis Report (DI-NUOR-81405) is approved by the AFSEC, a nuclear safety design certification letter is issued at the completion of all safety design certification tasks. Where an NSAR is neither required nor appropriate, an Engineering Evaluation Report (DI-NUOR- 81411) supports nuclear certification requirements.
d. Department of Defense Instruction (DoDI) 3150.09, Chemical, Biological, Radiological, and Nuclear (CBRN) Survivability Policy, 1.b, "Establishes policy, assigns responsibilities, and establishes procedures for the execution of the DoD CBRN Survivability Policy (including electromagnetic pulse (EMP))." AFI 10-2607, Air Force CBRN Survivability, 1.1.2, "The Lead Command/Sponsor must ensure nuclear systems, nuclear command and control (NC2) systems, and associated facilities and equipment are hardened against CBRN attacks and have a continuing nuclear hardness maintenance and hardness surveillance (HM/HS) program." Survivable nuclear weapons need survivable support equipment. To address the interrelation of survivability with safety and security, AFNWC established the Nuclear Technology Analysis (NTA) division, which provides scientific oversight of the RN part of the CBRN (Chemical, Biological, Radiological, Nuclear) survivability mission. NTA monitors development and modification of nuclear weapons, their components, or subassemblies for compliance with military characteristics and stockpile-to-target sequence survivability requirements.
e. Handbook MIL-HDBK-526 (formerly AFNWCH63-100) provides reference information for understanding the nuclear weapon compatibility certification process for USAF aircraft. This handbook references MIL-STD-1822 requirements and the aircraft compatibility certification portion of AFI 63-125.
Purpose. This military standard identifies the requirements that are necessary to assure compatibility between National Nuclear Security Administration (NNSA) developed nuclear weapons and DoD operational nuclear weapon delivery systems and support equipment. Requirements for evaluation and reporting for nuclear compatibility certification are also delineated.
Applicability. This document applies to Air Force nuclear weapon systems. Modified portions of nuclear weapon systems will also comply with this document. This document complements AFI 63-125.
This document is intended for use in the procurement or modification of Air Force nuclear weapon systems, subsystems and support equipment.
