The PV/S Program and Staff are now part of KSC Safety and Mission Assurance Directorate (SA)
The NASA PV/S program is lead by the pressure systems manager (PSM).
The PSM is responsible for ensuring compliance to KNPR 8715.3 Attachment
E, which complies with NASA policy's NPR 1710.5 and NASA-STD-8719.17. The
PSM holds quarterly PV/S Safety Committee meetings with the O&M contractors,
and NASA systems engineers to discuss current certification and inspection
status, important code or policy changes, any incidents in the previous
quarter, or other PV/S issues.
NASA PV/S is charged with ensuring all new designs and procurements comply
with the ASME Boiler and Pressure Codes, and the appropriate piping standard.
Designers should be sure to include PV/S representation on their 30/60/90
and 100% design reviews to ensure PV/S certification requirements are met
before installation and operation.
The PV/S program covers both internal and external (vacuum) pressure vessels
and pressure systems. There are very few exemptions to certification, and
those can be found in KNPR 8715.3, but exemptions must be cleared through
the PSM and documented. Mobile Equipment operated and maintained on KSC
are 49 CFR compliant.
Examples of covered PV/S include:
- Cryogenic Dewars
- Pipelines/Piping Systems
- Large air receivers
- Vacuum vessels
- Pressure vessels
KSC has approximately 3,000 pressure vessels and related systems.
The certification is a review of the related manufacturing documentation,
an inspection of the vessel or system, and its operating history. The
certification also includes a schedule for inspections and recertification
PV/S questions or concerns should be directed to the Pressure
