If it meets certain minimum requirements (stored energy, pressure, fluid etc) certain actions must be taken. Relief calculations are just one of the requirements. Assigning a Design Authority another. Depending on the characteristics of the system, a Pressure System number may need to be defined as well as the accompanying documentation. The Design Engineer can make this call.<br></div><br><div>Cheers,<br></div><br><br><div>Tim Whitlatch<br>Hall D Engineer<br>Jefferson Lab<br>600 KELVIN DR STE 5<br>Newport News, VA 23606-4468 <br>757-269-5087</div><br><hr id="zwchr"><div><b>From: </b>"Amrit Yegneswaran" <yeg@jlab.org><br><b>To: </b>"David Kashy" <kashy@jlab.org>, "Timothy Whitlatch" <whitey@jlab.org>, "dsg-rich" <dsg-rich@jlab.org><br><b>Cc: </b>"Patrizia Rossi" <rossi@jlab.org><br><b>Sent: </b>Tuesday, November 8, 2016 1:07:26 PM<br><b>Subject: </b>Fwd: List of Design Authority for Pressure Systems<br></div><br><div><div style="font-family: tahoma,new york,times,serif; font-size: 14pt; color: #009900" data-mce-style="font-family: tahoma,new york,times,serif; font-size: 14pt; color: #009900;"><div><span style="color: rgb(0, 0, 255);" data-mce-style="color: #0000ff;">hello everyone,</span><br></div><div><span style="color: rgb(0, 0, 255);" data-mce-style="color: #0000ff;">i'm at a complete loss. <br></span></div><div><span style="color: rgb(0, 0, 255);" data-mce-style="color: #0000ff;">saptarshi's e-mail from july 13, 2017 shows that saptarshi had done the calculation and that joe matalevich, was supposed to check the calcs. i asked saptarshi to charge the bops account. <br></span></div><div><span style="color: rgb(0, 0, 255);" data-mce-style="color: #0000ff;">so, in principle the calcs have been done and should have been checked buy joe.<br></span></div><div><span style="color: rgb(0, 0, 255);" data-mce-style="color: #0000ff;">we need to send this over to tim, right?<br></span></div><div><span style="color: rgb(0, 0, 255);" data-mce-style="color: #0000ff;">or am i missing something?<br></span></div><div><span style="color: rgb(0, 0, 255);" data-mce-style="color: #0000ff;">amrit<br></span></div><br><hr id="zwchr"><div><b>From: </b>"Saptarshi Mandal" <mandal@jlab.org><br><b>To: </b>"Amrit Yegneswaran" <yeg@jlab.org><br><b>Sent: </b>Wednesday, July 13, 2016 10:04:11 AM<br><b>Subject: </b>Re: List of Design Authority for Pressure Systems<br></div><br><div>Hi Amrit,<br><br>Joe Matalevich from the Engineering group has agreed to verify my relief <br>valve calculations for the RICH cooling system but he needs a charge <br>code for it.
