Background

The SMiRF facility currently utilizes a Dynavac Cryoshroud assembly to control the environmental temperature in our test chamber. The test chamber has two lids that allow for simultaneous build-up and testing of hardware for multiple test programs. The facility currently utilizes one Cryoshroud top section that needs to be moved between the two test tank lids during test build up. The procurement of this top section is to be an exact replica of the current hardware, to be installed onto the second lid for faster integration of test specific items into the chamber. This will allow the team to build up for future testing efforts, while the existing top section is used for testing.

No environmental impacts.

Pressure Vessels and Systems

Does this work include pressure vessels and systems? Yes

The cold wall is considered a pressurized system. This component is a part of the Liquid Nitrogen system in building 402, all subsequent certifications and inspections will be included in this systems renewal process (System# 414-0402-01N). Since we are obtaining a replica of an existing system, no design or operational procedures are necessary for the fabrication of the hardware. Several tests will be performed during the fabrication process to confirm the safety and functionality of the top section component (see below for specific tests).

APPENDIX A: GROUND-BASED PRESSURE VESSEL AND SYSTEMS PURCHASES

NASA policy requires that the Pressure Systems Manager (PSM) review ground-based pressure vessel and systems (PVS) design and procurement specifications for compliance with NPD 8710.5 and NASA Standard 8719.17, which require that all new PVS be designed, acquired, fabricated, inspected, tested, installed, repaired, altered, operated, and maintained in accordance with the applicable codes, standards, guides, and regulations. Further, all flexible hose purchases shall conform to Glenn Safety Manual Chapter 7, paragraph 6.3.

The GRC PSM grants technical review authority to the PVS owner’s organization. However, to avoid potential cost and schedule delays resulting from PVS that are not compliant with NPD 8710.5 and NASA Standard 8719.17, PVS requesters are strongly encouraged to involve the Pressure Systems Office (PSO) as early in the project effort as possible (e.g. – invite the PSO to participate in all reviews, seek the feedback of the PSO on specifications prior to the purchase of significant PVS), instead of waiting to obtain PSO concurrence during the safety permitting and recertification process.

If a PVS requester is unsure regarding the PVS’s code compliance, and/or proper application of the PVS in an existing or new system (i.e. design pressure/ Maximum Allowable Working Pressure (MAWP), minimum design metal temperature, maximum design temperature, commodity compatibility, etc.) it is best to request a PSO review prior to initiating a procurement activity.

A PSO review may be requested by calling the Contact the PSO Help Line at (216) 433-2973 or by e-mail at grc-pso@mail.nasa.gov. All requests should include the following pertinent information:

http://pso.grc.nasa.gov/DocumentFiles/PSODocs/7330/New Construction Documentation Checklist 6- 1-2010.pdf. Electronic files can be transmitted via e-mail and hardcopies can be sent to the PSO at MS 6-8. Where the review request involves the replacement of existing recertified PVS, please provide the recertification tag numbers of the PVS being replaced.
