“…The system component heights and elevations have been preserved to simulate gravity dominated natural circulation flow processes correctly. The original facility description is made available by Tuunanen et al in [4] and presented also by Purhonen et al in [1][2][3]. Some of the PACTEL facility characteristics compared with the reference reactor are shown in Table 1.…”

“…During the years, the PACTEL facility has gone through several structural changes due to the different objectives and scaling requirements of the individual test programs. Equipment upgrades dictated by maintenance needs as well as instrumentation and software upgrades to take advantage of the developments in the field of measurements and data acquisition have also been made as presented in [2,3].…”

“…As described in Chapter 2.1, PACTEL has introduced already two sets of different steam generators, the original long and narrow ones and the present short and thick ones described by Purhonen et al in [1][2][3][4]. Recently, the core channel construction has also been refurbished and renovated, yet the geometry and core configuration principles [1][2][3]. However, the fundamental and original PACTEL construction has been restored each time.…”

“…Experimental work with the separate effect test facilities and the large integral test facility has generated a wide data base containing about 900 experiments. Along the years the cooperation with Technical Research Centre of Finland (VTT) induced the decisions to build many of the test facilities utilized at LUT, including the largest one, that is, the parallel channel test facility (PACTEL), described in [1][2][3][4].…”

This paper describes construction and experimental research activities with two test facilities, PACTEL and PWR PACTEL. The PACTEL facility, comprising of reactor pressure vessel parts, three loops with horizontal steam generators, a pressurizer, and emergency core cooling systems, was designed to model the thermal-hydraulic behaviour of VVER-440-type reactors. The facility has been utilized in miscellaneous applications and experiments, for example, in the OECD International Standard Problem ISP-33. PACTEL has been upgraded and modified on a case-by-case basis. The latest facility configuration, the PWR PACTEL facility, was constructed for research activities associated with the EPR-type reactor. A significant design basis is to utilize certain parts of PACTEL, and at the same time, to focus on a proper construction of two new loops and vertical steam generators with an extensive instrumentation. The PWR PACTEL benchmark exercise was launched in 2010 with a small break loss-of-coolant accident test as the chosen transient. Both facilities, PACTEL and PWR PACTEL, are maintained fully operational side by side.
