We can&amp;#x27;t build it!&lt;p&gt;Why is this plant shutting down? Not because of some sort of hate of nuclear technology, as many would have us believe.&lt;p&gt;No, the real reason this plant is shutting down is because, like every other thermal generation plant, extending its lifetime past the original license means complying with environmental impact laws on waste heat. Once-through waste heat systems are no longer legal [1]. So why not just build a waste heat system and keep it running? Because when the utility tried to come up with one, the cost of  &lt;i&gt;the cooling system alone&lt;/i&gt; ran into the billions of dollars!&lt;p&gt;Much better to just by a few billion dollars worth of batteries and site them on location. At current costs, today, $1B gets you 5GWh at 1.25GW, roughly. The very cheapest estimate for a cooling system was $7B and they ran to over $10B for a new cooling system [2]. So even without the inevitable cost overruns, one could purchase 35-50GWh and 9-12GW of batteries.&lt;p&gt;A 40GWh&amp;#x2F;10GW battery would be a far better grid asset for California, and massive increase reliability far beyond what Diablo Canyon could ever produce.&lt;p&gt;When the mere cooling system for nuclear is more expensive than a better battery, the technology is dead, dead, dead. We don&amp;#x27;t need it and we have better alternatives.&lt;p&gt;[1] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.sanluisobispo.com&amp;#x2F;news&amp;#x2F;local&amp;#x2F;environment&amp;#x2F;article39459930.html&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.sanluisobispo.com&amp;#x2F;news&amp;#x2F;local&amp;#x2F;environment&amp;#x2F;article...&lt;/a&gt;&lt;p&gt;[2] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.waterboards.ca.gov&amp;#x2F;water_issues&amp;#x2F;programs&amp;#x2F;ocean&amp;#x2F;cwa316&amp;#x2F;rcnfpp&amp;#x2F;docs&amp;#x2F;subbechcom_111314.pdf&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.waterboards.ca.gov&amp;#x2F;water_issues&amp;#x2F;programs&amp;#x2F;ocean&amp;#x2F;c...&lt;/a&gt;</text></comment>
