The Question:
This element is 4.5 times heavier than air. This element is the most
significant (and unwanted) neutron absorber in nuclear reactors. The
element is emitted from some mineral springs. The planet Jupiter has an
abundance of this element in its atmosphere. The World Anti Doping Agency
(WADA) added this element to its list of prohibited substances. Which
element is being described?
The Answer:
The element is Xenon (Xe)! Xenon derives its name from the Greek word
"xenos" meaning 'foreign(er)', 'strange(r)', or 'guest'. Xenon has a huge
cross section for thermal neutrons and operates as a neutron absorber or
"poison" that can slow or stop the chain reaction after a period of
operation. This was discovered in the earliest nuclear reactors built by
the American Manhattan Project for plutonium production. Fortunately the
designers had made provisions in the design to increase the reactor's
reactivity (the number of neutrons per fission that go on to fission other
atoms of nuclear fuel). Xe reactor poisoning was a major factor in the
Chernobyl disaster. A shutdown or decrease of power of a reactor can result
in buildup of 135Xe, with reactor operation going into a condition known as
the iodine pit. Inhaling a xenon/oxygen mixture activates production of the
transcription factor HIF-1-alpha, which may lead to increased production of
erythropoietin. The latter hormone is known to increase red blood cell
production and athletic performance.
The winner of the quiz is Leland Woodall and he will get the services
of Clumpy
and Kloumpios for the week.
The EQAB reviewed Doug's submission of "Stupidium" and unfortunately had to
disqualify his reponse. Detailed discussions with NASA failed to confirm
the information he provided. Additionally, a review of the global spectral
databases failed to show a spectral fingerprint for the "Stupidium"
element. EQAB is pursuing a possible connection of his half fraction
element and some government offices but that assessment has not been
completed.
So far Clumpy and Kloumpios have done the following:

Week 56 Mordechai Kirshenbaum
- I picked the boys from Ben Gurion Airport after a 24 hr delay. I shall
let them to overcome the Jet Lag, but tomorrow they are going to work hard
at my labs. I hope they will enjoy their stay
Week 57 Steve Herring, Pennatronics Corp
- We have two new SPI's being installed and validated next week, so I'm
sure we can use the help. I hope they are brushed up on statistics and
Minitab, as a whole lot of number crunching will be going on!
Week 58 Leland Woodall
- The boys will be doing a round of golf tomorrow morning, yard work
tomorrow afternoon, and we'll all be eating grilled burgers tomorrow evening
while watching the Kansas race. I want them to relax a bit before they
continue helping me perform more TS to IATF document conversion next week.
Week 59 Drew Meyer, Benchmark
- Wow! Simply amazing timing. Our leader will be gone next week so we
will be two people doing the work of three. The boys will be greatly
appreciated. The good news for them is that we finally have some decent
weather here. Will have to get them some time outside to enjoy it!
Week 60 Leland Woodall
- assisted with ????
I hope everyone has a awesome week! (no quiz next week due the US holiday
and I am whitewater kayaking so the boys are hauling my boat)
