Fort Calhoun is evaluating the implications of switching to a different TLD vendor. A change would most likely result in changing from the Panasonic UD-802 TLD to Landauer OSL or Harshaw 760 as they are the most prevalent in the industry.
Would appreciate any light you can shed on these questions, or anything else I failed to ask here that you think is relevant - 1) If you have switched TLD vendors within the last several years, what process did you follow and what were your experiences making this transition? What recommendations would you have to make this a smooth transition? 2) If you have changed the type of TLD you used, same question as above 3) If you use either Landauer OSL or Harshaw 760 TLDs, what is your experience with them for normal use? 4) What is your experience for measuring neutron during containment entries at power or dry cask storage activities? 5) Do you use the OSL or Harshaw with the lithium on one of the elements or the CR-39 chip, or both? Your experience with neutron measurement using these TLDs? 6) If you use Mirion or Landauer as a TLD vendor, how would you rate their performance and abilities? Any areas where they excel or are lacking? 7) If you use the Harshaw, do you use the copper doped version? If not, how come? 8) What TLD do you use for area monitoring? What impact did changing vendors or TLDs have on area TLD results? Feel free to reply to powernet, or email or contact me directly. Documentation you are willing to share is also welcome.
