<h3>Key Developments</h3>
<ul>
<li>IAEA observed heightened activity at a “key complex” suspected to house the new enrichment plant.</li>
<li>Experts note that <span class="key-term" data-definition="Uranium enrichment — the process of raising the concentration of U‑235 isotope, enabling both civilian reactor fuel and weapons‑grade material (GS3: Energy)">uranium enrichment</span> offers a more efficient route to weapons‑grade material than the traditional reprocessing of <span class="key-term" data-definition="Spent plutonium reprocessing — extracting plutonium from used nuclear fuel to produce fissile material (GS3: Energy)">spent plutonium</span>.</li>
<li>The IAEA’s assessment follows a series of satellite‑imagery reports indicating construction of large‑scale centrifuge halls.</li>
</ul>
<h3>Important Facts</h3>
<p>The enrichment route bypasses the need for a large stockpile of plutonium, allowing faster accumulation of <strong>weapons‑grade uranium</strong>. The new facility, if operational, could increase North Korea’s fissile material output by an estimated <strong>30‑40 %</strong>, according to unnamed experts. This development comes amid ongoing UN sanctions and diplomatic efforts to curb Pyongyang’s nuclear programme.</p>
