छोटे मॉड्यूलर रिएक्टर परमाणु विखंडन ऊर्जा प्रणालियाँ हैं जिनकी विद्युत उत्पादन क्षमता आमतौर पर 300 मेगावाट प्रति इकाई से कम होती है, जिन्हें शुरू से ही मानकीकृत मॉड्यूल के कारखाने में निर्माण, सड़क या रेल द्वारा स्थल तक परिवहन और त्वरित निर्माण समय-सारणी के लिए डिज़ाइन किया गया है - यह गीगावाट-पैमाने के कस्टम-निर्मित परमाणु संयंत्रों का एक जानबूझकर किया गया संरचनात्मक उलटफेर है, जिनकी पूंजीगत लागत में वृद्धि और दशकों लंबी निर्माण समय-सीमा ने 1980 के दशक के बाद पश्चिमी बाजारों में नए परमाणु संयंत्रों की तैनाती को प्रभावी रूप से रोक दिया था।
डिजाइन पोर्टफोलियो में रिएक्टर भौतिकी और शीतलक रसायन विज्ञान में काफी भिन्नता पाई जाती है - उन्नत हल्के जल रिएक्टर जो सिद्ध दबावयुक्त जल प्रौद्योगिकी को कम पैमाने पर विस्तारित करते हैं, पिघले हुए नमक रिएक्टर जो ईंधन को सीधे फ्लोराइड या क्लोराइड शीतलक में घोलते हैं, हीलियम और TRISO ईंधन कणों का उपयोग करने वाले उच्च तापमान गैस-शीतित रिएक्टर, सोडियम-शीतित और सीसा-शीतित तीव्र स्पेक्ट्रम डिजाइन, और 10 मेगावाट से कम के दूरस्थ औद्योगिक या सैन्य स्थलों को लक्षित करने वाले थर्मल माइक्रोरेक्टर।
