<p class="MsoNormal">Looking for alignment with the Industry in regards to handling the source in the Explosive Monitors. The tag below is from the type of Explosive Monitor “Entry Scan 4” that TVA has in use. The 10 mCi Ni-63 source in the explosive monitors
are exempt from any regulatory requirement per 10 CFR 32.27 although we have kept them on our inventory list. We eliminated conducting leak tests on these sources a few years ago based on this exemption although we still inventory them every six months. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Q. - For the plants which have the “Entry Scan 4” do you keep them on your sealed source inventory list?<o:p></o:p></p>
<p class="MsoNormal">Q. - Did you remove them completely or did you change their status to “stored not in use”?
<o:p></o:p></p>
<p class="MsoNormal">Q. - Do you perform any type of leak test (either routine or maintenance)?<o:p></o:p></p>
