Abstract

In 2000, the TRIGA 2000 reactor in Bandung completed a commissioning program and received an operating license at 2000 kW. The Indonesia regulatory body (BAPETEN) issued a 15-year license, to operate the reactor at 2000 kW. During the commissioning tests, bubbling at the reactor core was observed and considered acceptable by General Atomic experts. The sub-cooled boiling observed during the commissiong tests confirmed the predictions of the thermal hydraulics calculations performed by General Atomics and presented in the safety analysis report. In 2004 the operating staff of the Bandung TRIGA 2000 Reactor observed an increase in the amount and size of the bubbles emanating from the core and in January 2005 the BAPETEN after an inspection and discussion with the operating irganization decided to limit the reactor power to 1250 kW. In January 2005, IAEA team mission organize a favt-finding mission to have a better understanding of the safety implications of the reactor bubbling and to propose an action plan to address and solve the issue. Followint this obligation, BATAN submitted to the Agency the current verison of the SAR at the end of 2007. In March 2007, IAEA team mission came to Indonesia di review the SAR was combined with the follow-up on the recommendation from previous mission on investigation of core bubbling phenomena,

Abstract

Lingkup studi eksperimental dalam makalah ini mencakup aspek termohidralik berkas empat pipa susunan sebaris pada fasilitas NILO I. Aspek termohidrolik dalam reaktor nuklir memegang peranan yang sangat penting ,karena berkaitan dengan keselamatan reakto. Pada penelitian ini dilakukan pengamatan secara eksperimen aspek termohidrolik sub-buluh denganmempergunakan tabung pipa uji yang terdiri dari empat pemanas. Sub-buluh pada penelitian ini dibagi ke dalam tiga bagian, sub-buluh tengah, sub-buluh pinggir, dun sub-buluh pojok. Setiap sub-buluh dibagi ke dalam delapan uni! sel dalam arah aksial. Data hasil pengamatan eksperimental distribusi temperatur yang didapatkan dibandingkan dengan hasil analisis numerik sub-buluh. Distribusi koefisien perpindahan panas lokal pada setiap sub-buluh dihitung berdasarkan data percobaan, kemudian dicari korelasi antara bilangan Nusselt, ReynoIds dan Prandtl. Distribusi temperatur dari hasil percobaan lebih rendah dibandingkan dengan hasil simulasi numerik, sedangkan korelasi antara bilangan Nusselt, Reynolds dan Prandtl yang didapat dari hasil percobaan tidak sesuai dengan korelasi yang ditunjukkan oleh Dittus-Boelter.
