Abstract

ABSTRACT
ANALYSIS OF PRESSURE LOSS IN CHANNEL EXPERIMENTAL FACILITY. Channel
Experiment Facility (ExNal) is an experimentation facility that can be used to simulate the
flow rate of coolant to the research reactor. ExNal can be used to understand the potential
occurrence of vibration in the fuel plate. Potential vibration is necessary to know due to
vibration can accelerate materials fatique and ultimately could lead to material damage such
as cracked fuel and even rupture. From previous research facilities have not been able to
achieve the critical speed of 18.062 m/s. The purpose of this study is to analyze the loss of
pressure that occurs in parts ExNal. That methodology of research done by calculating the
pressure loss through the approach of critical velocity coolant flow that can be known pump
efficiency at the ExNal facility. The result showed 0.64 bar of total loss pressure and 64% of
pump efficiency. Therefore, parameters such as fluid velocity, flow rate and pressure has not
approached the expected results, the capacity of the pump must be improved.
Keywords: experimental channel, the pressure loss, pump efficiency, critical speed, vibration
ABSTRAK
ANALISIS KERUGIAN TEKANAN PADA FASILITAS EKSPERIMEN KANAL. Fasilitas
Eksperimen Kanal (ExNal) adalah sebuah fasilitas eskperimen yang dapat digunakan untuk
mensimulasikan kecepatan aliran pendingin pada reaktor riset. ExNal mampu digunakan
untuk memahami potensi terjadinya vibrasi pada pelat bahan bakar. Potensi vibrasi ini perlu
diketahui karena vibrasi dapat mempercepat kelelahan material dan akhirnya akan dapat
memicu terjadinya kerusakan material bahan bakar seperti retak dan bahkan pecah. Dari
penelitian sebelumnya fasilitas ini belum mampu mencapai kecepatan kritis sebesar 18,062
m/s. Tujuan dari penelitian ini adalah menganalisis rugi-rugi tekanan yang terjadi pada
bagian-bagian ExNal. Metodologi penelitian dilakukan dengan perhitungan kerugian tekanan
melalui pendekatan kecepatan kritis aliran pendingin sehingga dapat diketahui efisiensi
pompa pada fasilitas ExNal. Dari hasil penelitian diperoleh kerugian tekanan total sebesar
0,64 bar dan efisiensi pompa sebesar 64%. Oleh karena parameter-parameter seperti
kecepatan fluida, debit aliran dan tekanan belum mendekati hasil yang diharapkan,maka
kapasitas pompa harus ditingkatkan.
Kata kunci : eksperimen kanal, rugi tekanan, efisiensi pompa, kecepatan kritis, vibrasi
