Telaah – Perkembangan Nuklir Indonesia

Oleh: Adjar Irawan S Hidayat, pemerhati nuklir, alumni Fisika ITB tahun 1967, operator angkatan pertama reaktor Triga Mark II tahun 1964, dan Ketua Asosiasi PBB Indonesia (United Nations Association in Indonesia) sejak 1973-sekarang. Dia juga peraih Piagam Pembawa Pesan Perdamaian (Peace Messenger) PBB tahun 1994.

Bulan Oktober 1964, bangsa Indonesia mulai berbicara tentang reaktor nuklir, terhitung sejak “criticality-experiment” terhadap reaktor nuklir pertama Triga Mark II di Bandung berhasil dilakukan dengan baik.

Pemimpin percobaan Djali Ahimsa menulis dalam “log-book” tertanggal 16 Oktober 1964 : 18.37,5?, predict 57,5 critical. Catatan itu menunjukkan bahwa pada jam tersebut sebanyak 57,5 batang elemen bakar nuklir (berisi 2,3 kg U-235) telah dipancingkan ke dalam teras reaktor dan pada kondisi itu reaksi inti yang berkesinambungan tepat sudah bisa terjadi. Besaran 2,3 kg U-235 disebut bobot-kritis. Kritis di sini tidak ada kaitannya dengan bahaya. Jauh hari kemudian, kepala proyek pembangunan reaktor Triga, Djali Ahimsa, menjadi Dirjen Batan. Ketika itu, para pakar yang terlibat bersorak gembira dan lega.

Study “Nuclear Engineering” in Korea

Nuclear power in Korea has become a big industry since their first nuclear power plant, Kori 1, put into commercial operation in 1978. Currently 20 nuclear power plants are operating; 4 units of PWRs at Kori, 4 units of PHWRs at Wolsung, 6 units of PWRs at Youngkwang and 6 more units of PWRs at Uljin; and eight units of PWRs are under construction or on order. Korea’s nuclear power generation technology has continuously advanced, and today, its nuclear technology has reached to a standard that is on par with the most advanced countries of the world.

The total capacity of Korea’s nuclear power plant generation is 17.716 MWe. These nuclear power reactors are supplying about 40.3% of the total electric power demand. Its capacity is approximately 28.4% of Korea’s total electric power generation. In 2005 the capacity factor for South Korean power reactors averaged 96.5% – one of the highest in the world. And most important, there is no severe nuclear accident recorded in Korea.
