Re: quench water sampling

Its only 9 sample for all. The 3 days is only to make sure the tests were not done on same day. This is a rearrangement of the instructions that may make it more clear.

"Perform three tests (three samples each test, where each test is on a separate day) over a minimum of 20 quenches. Take the water samples immediately after quenching."

On your other question, you are correct: "Essentially, I cannot conduct grabs during three consecutive quenches and be done."  Your example is good. Could be 1, 10, 20 quench# or any number close to #10 in between. And any number of 20. So, #1, #20, #40 is also fine.

From page 17 of the Enclosure 2 under TDS sampling: Perform three tests (three samples each test) over a minimum of 20 quenches, which occur on at least three (3) separate test days. Take the water samples immediately after quenching.5

I'm reading that as 3 tests x 3 samples per test x 3 days = 27 samples, hence my request for clarification.  The TDS sampling requirement was written differently from the other parameters, which lead me to believe it was >9 samples.

Thanks,

Where do you see the "3 times per day" in Enclosure 2?

Subject: quench water sampling

Dr. Jones,

I'd like to get some clarification quench water sampling during the ICR testing.

To make sure my math is right... we're collecting 3 grab samples, 3 times per day for 3 days.  That's 27 total grab samples for TDS.  For all the other quench water parameters like HCl, semi-vols, etc. the minimum number of samples is 9 (3 grab samples for 3 days).  Is that correct?

On page 17 of the 6/24/16 redline version of Enclosure 2 there is a requirement to collect TDS samples "...over a minimum of 20 quenches.."  I'm interpreting that as all 3 tests on that day can be collected between quench 1 and quench 20 in any given sequence, e.g., collect 3 samples on quench #1, quench #10, and quench #20.  Essentially, I cannot conduct grabs during three consecutive quenches and be done.  Can you clarify?  Maybe an example of what you'd like to see would explain it better.

Thanks for the help.
