That is often repeated, but incorrect.
It would indeed multiply the price of uranium about 4 times, but the end result is that the price of electricity produced by the nuclear power plants would increase with less than 1 cent per kWh, and that's what matters. For comparison, the average retail price of electricity in the US is about 15 cents per kWh.
Here's the math, if you are curious: on average a PWR nuclear power plant produces 50 GW-day of electricity from one ton of enriched uranium, and you need about 10 tons of natural uranium to get that, so that's 5 GWd per ton of raw uranium. The current market price of uranium is $74/pound [1], or $163/kg. It is estimated that it would take $640/kg to extract uranium from sea water [2]. So, this is roughly $480/kg more expensive. 1 kg of Uranium results in 5 MWd or 120 MWh, so the increase in uranium price would result in $4 more for 1 MWh, or 0.4 cents per kWh.
