- THIS NOTICE CONSTITUTES MODIFICATION NO. 2 TO THE COMBINED SYNOPSIS/RFQ FOR BELLOWS-STYLE XENON PUMP. Companies shall acknowledge all amendment(s) in their solicitation. This notice serves as the official amendment to subject Request For Proposal and a written amendment will not be issued. The purpose of this modification is to release the updated specification with the following changes: Cover: A couple of the names in the signature blocks have changed. Table of Contents and List of figures: Page numbers updated. Section 1. Scope, 3rd sentence, The pump shall be designed/fabricated Section 3.2.1.2 The pump shall have a maximum expected operating pressure (MEOP) of no less than 1950 psig. Section 3.2.1.3 The pump shall be capable of pressurizing the working media up to at least 1750 psia. Section 3.2.1.4 The pump shall be capable of operating with an inlet pressure of 100 psia or lower. Section 3.2.1.9.1 System contains 2 tanks, one for supply and one for delivery, both of which are initially at 600 psia & -10 to +20 degrees Celsius and contain xenon. Each tank has a water volume of 1 L (0.035ft3). Section 3.2.1.10 The pump shall have a flow rate such that the above operational cycle can be achieved within no less than 20 minutes and no more than 2 hours. Section 3.2.2.5 The pump shall measure no more than 14 x 10 x 4 (or equivalent volume approved by NASA). Section 3.2.2.6 The pump should draw no more than 45 watts of power but shall not draw more than 60 watts of power. Section 3.2.2.7 The pump assembly should weigh no more than 8 pounds but shall not weigh more than 12 pounds. Section 3.3.5Class A welds are all pressure containing welds with the exception of edge-welded bellows seams (if used). This line was added to be clear on subsequent requirements. All subsequent lines within section 3.3 are indexed up 1 number. Section 3.3.7All non-Class A welds on pressure containing parts must be 100% Non-Destructive Evaluation (NDE) volumetric inspected or equivalent methods ensuring similar quality such as automated processes / alternative NDE such as destructive evaluation of sample welds with metallurgical cross-sections under magnification. Section 3.3.8Welded parts of the pump housing shall have an allowable leakage of less than 1 x 10-9 standard cc/sec gaseous helium when pressurized to 675 psia for 30 minutes and to be inspected with a mass spectrometer rated to 1 x 10-10 standard cc/sec gaseous helium of better. (section added due to lessons learned in previous procurement) Section 3.3.8.1 Welded parts of the bellows shall have an allowable internal and external leakage of less than 1 x 10-9 standard cc/sec gaseous helium when pressurized to 150 psia for 30 minutes and to be inspected with a mass spectrometer rated to 1 x 10-10 standard cc/sec gaseous helium or better. (section added due to lessons learned in previous procurement) Section 3.3.9Mechanical joints on the pump housing shall have an allowable leakage of less than 1 x 10-6 standard cc/sec gaseous helium when pressurized to 675 psia for 30 minutes and to be inspected with a mass spectrometer rated to 1 x 10-7 standard cc/sec gaseous helium of better (section added due to lessons learned in previous procurement) Section 4.1 Burst Test moved to end of section (and consequently to end of Table 1). Content remains unchanged. Done for clarity (and per instruction by Chief Engineer). The due date for receipt of offers is not extended. Companies shall provide the information stated in the synopsis/RFQ posted on the NASA Acquisition Internet Service (NAIS) on September 2, 2014. Documents related to this procurement are available over the Internet. These documents reside on a World Wide Web (WWW) server which may be accessed using a WWW browser application.
