That's hardly a valid concern. "The elevation of the Fukushima site is approximately 20 feet [6m] above sea level, while Diablo Canyon sits on a bluff 85 feet [26m] above sea level." [Wikipedia]
Furthermore, people seem to ignore one of the very favorable attributes of Diablo Canyon - it was designed to be paired with a large pumped storage facility, so that power generated overnight is available for peak use during the day.
"The Helms Pumped Storage project was designed to be used with the Diablo Canyon Nuclear Power Plant, also owned by PG&E, in the 1970s, when Diablo Canyon was being designed and permitted. It is connected to that power plant by a dedicated high-tension power line." [Wikipedia]
Demand is higher during the day. solar matches this better than the flat production of nuclear, so less storage per watt of production is needed for cheap solar energy when used to pump hydro storage, and even non pumped hydro can be varied to complement solar production and demand needs (within certain limits). And seasonally hydro and solar complement each other.
The land usage of pumped hydro isn't great, but since that's the same between both we'll ignore it for now.
Since the solar can be placed on top of the hydro dam water, or on the top of buildings, or used to shelter crops, the land use can and should be negative.
I very much doubt nuclear takes less material resources, but I don't have any good numbers for that off hand. Generally, cost is a reasonable proxy for energy and material input though (in the absence of large externalities) and solar costs less.
Again, hydro isn't super good for the environment, substiantially worse than nuclear and solar, but if you're going to build it to help nuclear deal with it's unhelpful power supply timing then you might as well use it for cheap solar.
And that's when you use hydro and batteries.
Here's the historical yearly peaks: https://www.caiso.com/documents/californiaisopeakloadhistory...
Note, in recent years this ignores home based solar, which also reduce the grid seen demand during the day, but the new peak is still before sunset.
The local grid refers to this post solar/wind demand as 'net demand peak':
> Net demand is the total electricity demand minus utility-scale solar and wind generation at a given time, and the net demand peak (the “net peak” for short) typically occurs later in the evening than the total demand peak.

> Initially, net demand peaked around the same time as total demand. Wind, which tends to pick up in the evenings, was responsible for most of the renewable generation. In 2013, solar began to eclipse wind. By 2016, the average timing of the net demand peak shifted from before 5:00 p.m. to around 7:30 p.m., where it has remained. (The total demand peak has also moved later in the evening to a lesser extent, driven by customer-owned solar.) Grid operators can’t turn to solar after the sun sets to meet the resulting net peak.
Luckily California has big plans for offshore wind, but that'll take about a decade. In the meantime solar and demand management is probably still the low hanging fruit.
Like Kamala Harris, he would make more sense as a VP nominee (although he would similarly be a bad choice overall). His politics and California provenance would be an albatross around any Presidential candidate's neck, but access to the lucrative California establishment Democrat donor network might outweigh the electoral deadweight.

> Kinney is well known around the state Capitol as a strategist, ghostwriter of Newsom’s speeches and unofficial fixer summoned to help loosen the governor from political jams. His dual roles as an advisor to Newsom and a lobbyist paid by companies to influence the governor and his staff have raised questions about potential conflicts of interest for the administration.
