For new systems, the applicant should provide items (a) through
(e) above to the SCA for review and/or approval prior to
conducting formal design reviews.
Items (f) through (k) should be forwarded to the SCA by the
applicant at least 60 days prior to convening each formal design
review or as required by the MES. The number and scope of formal
design reviews will be governed by the size and complexity of the
system and can be negotiated between the applicant and the SCA.
3.2.1
System Scope of Certification and Milestone Event
Schedule. The applicant should submit the SOC and MES (both
described in Section 2) to the SCA for review and approval.
Summary Description of the System. To aid the SCA in
3.2.2
performing a safety evaluation, the applicant should submit a
summary description of the pressure vessel system including
design and construction details. A written explanation of the
features of the system, along with appropriate schematic drawings
should be included. The content of the summary description should
be commensurate with the complexity of the system. Simple
systems need only brief summary descriptions; complex systems
obviously require more detail.
Subsystem Descriptions. Each subsystem within the SOC
3.2.3
should be described. These subsystems normally include fluid
systems, electrical systems, compressed air and gas systems, and
other significant mechanical, electrical, or structural features
required for the complete operation of the facility.
Each subsystem design submitted must include both a written
description and a function or flowchart diagram. The description
should clearly delineate objectives of the design. Safety
considerations should also be included. It should also include
an analysis of the consequences of a failure or loss in the
normal operating mode. The diagram should clearly show how the
subsystem accomplishes its intended function. Sufficient
information should be included to identify the specific
components and their location, size, material, etc.
Design Parameters. Design parameters of the system
3.2.4
must be identified. Design parameters provide the basis for
evaluating system adequacy. Design parameters that the applicant
must consider and which will be evaluated by the SCA include:
a)
Design safety factors
b)
Design life and service period (useful life, number
