Uranium-238 quiz: 3 questions
Three questions on the Uranium-238 card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
Unlike uranium-235, it is non-fissile, which means it cannot sustain a chain ______ in a thermal-neutron reactor.
Answer
reaction. Unlike uranium-235, it is non-fissile, which means it cannot sustain a chain reaction in a thermal-neutron reactor. From the Uranium-238 article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
Uranium-238. Uranium-238 67 · Jeremy Hansen 62 · Conor Woodman 59 · Milecastle 35 47 ATK in WikiCards.
Which of these Wikipedia articles is read the most in a year?
Answer
Jeremy Hansen. Jeremy Hansen 1,300,000 · Richard Proenneke 340,000 · Uranium-238 120,000 · Milecastle 35 470 Wikipedia reads over a year.
In a duel, each round asks a question like these about the opposing card, with 15 seconds to answer.
The facts on the card
The card carries these facts from its Wikipedia article.
- Unlike uranium-235, it is non-fissile, which means it cannot sustain a chain reaction in a thermal-neutron reactor.
- However, it is fissionable by fast neutrons, and is fertile, meaning it can be transmuted to fissile plutonium-239.
- 238U cannot support a chain reaction because inelastic scattering reduces neutron energy below the range where fast fission of one or more next-generation nuclei is probable.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Uranium-238 article was read about 120,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 67 and blocks with 36: each hit it takes is cut by 14 %.
How to get Uranium-238
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
