Radioactive Sources Carried on Payloads


In addition to the design requirements noted in 9.1.1, radioactive materials carried on payloads shall meet the following requirements:

C







9.2.1. Radioactive Sources Carried on Payloads General Design Requirements:

C







9.2.1.1. Radioactive materials carried aboard payloads shall be compatible with and have no adverse safety effects on ordnance items, propellants, high pressure systems, critical structural components, or FTSs.

C







9.2.1.2. Radioactive materials carried aboard payloads shall be designed so that they may be installed as late in the countdown as possible, particularly if personnel will be required to work within the system controlled radiation area (as defined in 45 SWI 40-201 and 30 SWI 40-101) while performing other tasks on payloads.

C







9.2.2. Radioactive Sources Carried on Payloads Test Requirements:

C







9.2.2.1. General. To launch radioactive materials, adequate tests shall be performed to characterize the survivability of the radioactive materials and any containment system, in the launch, abort, and destruct environments. The payload project shall also quantify any release of radioactive materials from these environments and provide the information to the appropriate local safety authority as identified by the PSWG and Range Safety.

C







Abort and destruct environments may induce damaging effects due to reentry, ground impact, explosion and fragment impact, fire, or mechanical crushing.

I







9.2.2.2. Test Plans, Test Analyses, and Test Results:

I







9.2.2.2.1. The appropriate local safety authority as identified by the PSWG and Range Safety shall approve test plans, analyses, and results.

C







9.2.2.2.2. The payload projects shall perform and document the results of radiation surveys of their radioactive sources before coming to the payload processing facility and launch site area.

C







9.2.2.2.3. The payload project shall coordinate and allow an initial radiation survey to be performed by the RPO/RSO the first time the source arrives at the payload processing facility and launch site area. Follow-on surveys may be required by the RPO/RSO and shall be coordinated and allowed.

C







9.2.2.2.1. The appropriate local safety authority as identified by the PSWG and Range Safety shall approve test plans, analyses, and results.

C







9.2.3. Radioactive Sources Carried on Payloads Launch Approval Requirements:

I







9.2.3.1. A payload project contemplating launch of any radioactive source shall notify Range Safety and PSWG of any intended launch of radioactive materials during the concept phase of the program and comply with AFI 91-110.

C







9.2.3.2. The payload projects shall also comply with 30 SW Supplement 1 to AFI 91-110 and 30 SWI 40-101 on the WR or 45 SWI 40-201 on the ER.

C







9.2.3.3. Certification of compliance with an equivalent government agency safety review and launch approval process is required for all payload projects.

C







9.2.3.4. NPR 8715.3 Chapter 6 and Presidential Directive/National Security Council (NSC) 25, dated 08 May 1996, Scientific or Technological Experiments with Possible Large-Scale Adverse Environmental Effects and Launch of Nuclear Systems into Space provide requirements for all payload projects proposing to use radioactive sources.

C







PD/NSC-25 establishes an Interagency Nuclear Safety Review Panel (INSRP) for major sources. Range Safety is a member to provide launch abort data and evaluation; therefore, some failure mode, breakup, and blast data may be obtained from Range Safety.

I







9.2.4. Radioactive Sources Launch Approval Data Requirements. Radioactive sources launch approval data requirements shall be submitted in accordance with Attachment 1, A1.2.4.11 of this volume.

C







9.2.5. Radiation Producing Equipment and Devices Data Requirements. Radiation producing equipment and devices data requirements shall be submitted in accordance with Attachment 1, A1.2.5.13 of this volume.
