ABSTRAK
PENGEMBANGAN SISTEM KENDALI PEMANAS BERBASIS LABVIEW UNTUK
EKSPERIMEN KONDISI TUNAK PADA FASSIP-02. Semenjak kejadian kecelakaan pada
PLTN Fukushima Daiichi, Maret 2011 di Jepang, pengembangan desain keselamatan
pembangkit listrik tenaga nuklir terus dilakukan. Salah satunya adalah aplikasi sistem
pendingin pasif (SPP) yang digunakan untuk keadaan darurat (transien) maupun recovery
akibat kecelakaan. Pusat Teknologi dan Keselamatan Reaktor Nuklir BATAN sejak tahun
2014 telah membangun fasilitas eksperimen untuk penelitian SPP antara lain FASSIP-01
dan FASSIP-02. Beberapa eksperimen menggunakan untai FASSIP-02 telah dilakukan pada
kondisi transien. Sangat diperlukan adanya sistem kendali pemanas untuk dapat dilakukan
eksperimen pada kondisi tunak. Pada kegiatan ini dilakukan pembuatan sistem kendali
pemanas. Tujuan kegiatan untuk mengontrol daya pemanas, sehingga diperoleh temperatur
WHT yang stabil sesuai temperatur seting. Daya pemanas mengalir melalui SSR yang
dikontrol. Sinyal kontrol SSR diberikan melalui modul NI-9476 berdasarkan program
berbasis LabVIEW. Sinyal kontrol diberikan ketika temperatur WHT dibawah temperatur
seting. Sinyal kontrol otomatis terhenti ketika temperatur WHT sama atau lebih tinggi dari
temperatur seting. Pengkondisian tersebut berlangsung secara terus menerus, sehingga
temperatur WHT stabil sesuai temperatur seting. Validasi sistem kendali dilakukan dengan
simulasi program dan eksperimen. Dari hasil simulasi program dan eksperimen dapat
disimpulkan bahwa temperatur WHT dapat dijaga stabil sesuai temperatur seting. Panas
sisa daya terkontrol dapat menaikkan temperatur WHT sebesar 0,870C.

ABSTRACT
DEVELOPMENT OF HEATER CONTROL SYSTEM BASED ON LABVIEW FOR
EXPERIMENTS OF STEADY STATE CONDITIONS IN FASSIP-02. Since the accident at
the Fukushima Daiichi nuclear power plant in March 2011 in Japan, the development of the
design of nuclear power plant safety has continued. One of them is the application of a
passive cooling system (SPP) that is used for emergencies (transients) and recovery due to
accidents. The Technology Reactor and Safety Center of BATAN's Nuclear since 2014 has
built experimental facilities for SPP research including FASSIP-01 and FASSIP-02. Some
experiments using the FASSIP-02 strand have been carried out in transient conditions. It is
very necessary to have a heating control system to be able to do experiments in steady state
conditions. In this activity a heating control system is made. The purpose of the activity is to
control the heating power, so as to obtain a stable WHT temperature according to the setting
temperature. Heating power flows through a controlled SSR. The SSR control signal is given
via the NI-9476 module based on LabVIEW based programs. The control signal is given
when the WHT temperature is below the setting temperature. The control signal
automatically stops when the WHT temperature is equal to or higher than the setting
temperature. The conditioning takes place continuously, so that the WHT temperature is
stable according to the setting temperature. Validation of the control system is done by
program and experimental simulations. From the results of program and experimental
simulations it can be concluded that the WHT temperature can be kept stable according to
the setting temperature. The controlled heat remaining power can increase the WHT
temperature by 0.870C.
