4 JAERI-M 7737 ROSA-II Test Data Report- 13 -Improved ECCS Injection Method- (Runs 502, 505, 506, 507) ROSA Group, Reactor Safety Laboratory 1 Division of Reactor Safety, Tokai Research Establishment, JAERI (Received June 6, 1978) Results of the ROSA-II test simulating a loss-of-coolant accident(loca) in a PWR are presented, including test conditions and interpretations of phenomena observed in test runs 502, 505, 506 and 507. Development tests were performed to find a more effective ECCS injection method than the existing one based on cold leg injection. A combined injection of hot water into upper plenum in early stage of blowdown and subsequent cold water into lower plenum is the most effective method for a cold leg break. A hot leg injection of a low pressure injection system is effective for direct core cooling and early reflooding. The generalization witì~ for actual reactors will require analyses with a reliable code.

7 JAERI M 7737 Summary The objective of the ROSA-II (Rig of Safety Assessment) test program is to investigate blowdown phenomena and ECCS (Emergency Core Cooling System) performance during a loss-of-coolant accident (LOCA) postulated to occur in a pressurized water reactor. For that purpose, a simulated experiment of LOCA including ECCS operation is performed with the use of the ROSA-II test facility which is designed to simulate the TROJAN reactor in terms of thermal hydraulic response. The facility consists of a pressure vessel with a simulated core, one operating primary loop and one blowdown primary loop both with a steam generator and a pump in addition to a pressurizer attached to the operating intact loop. ECCS is also provided to the facility with several injection locations. Normal operating conditions of the facility are 160 atg and 325 C in hot legs and break configuration and ECC water injection conditions can be chosen as experimental parameters. The details of the ROSA-II program and the description of the facility should be reffered to the previously published reports' '>' 2^. In the present report, part of the ROSA-II experimental results is given with interpretations of the data. The ovjective of test runs described in the present report is to verify improved ECCS injection methods which have been proposed by considering previous tests or results of preliminary analyses. One of the four runs was performed as a standard run with the same injection method as an actual PWR for comparison of effectiveness. The injection methods for each run are as."jllows: Run Upper Plenum Injection System Accumulator Low Pressure Coolant Injection 502 None Hot legs Lower plenum & blowdown loop hot leg 505 Upper plenum Lower plenum Hot legs with 124 C water 506 None Cold legs Cold legs 507 Upper plenum Cold legs Hot legs with 124 C water with larger flow Run 506 in the above table is the standard case and Run 502 is the analytically predicted effective case with accumulator (ACC) and low V

8 faerf-m pressure coolant injection (LPCI) system only similar to an actual PWR. The injection of LPCI into blowdown loop beside the lower plenum was added owing to a piping error in the actual test Run 502. Run 505 is the case with upper plenum injection system (UPIS) with hot water in addition to ACC and LPCI. Run 507 slightly altered from Run 505, is the case that might be applicable to existing PWRs with a slight design change. Experimental conditions for the four runs are almost the same and break condition in common is a double-ended cold leg guilotine break. HPCI was not used to clarify the effect of the injection method since effect of HPCI is insignificant in case of a large break. The following conclusions were drawn from the comparison of the results of each test run with the ROSA-II facility. (1) Injection method of Run 506 (ACC-cold legs, LPCI-cold legs) This combination of ECC injection shows the least contribution of accumulator to refilling. Furthermore the downward flow in the core is accelerated due to its condensation effect and thus core exposure becomes earlier. Reflooding of the core by LPCI is too late to prevent temperature rise of fuel rods and flow oscillation occurs between the core and the intact loop steam generator during reflooding the high temperature core by LPCI even after power termination. The oscillation is due to the fact that the two heat sources, i.e. core and steam generator alternately reject the injected water. This results in oscillation of accumulated water in longer period and gradual increase of the accumulated water level accompanied with quenched core from the bottom. (2) Injection method of Run 502 (ACC-hot legs, LPCI-lower plenum & blowdown loop hot leg) During accumulator injection, the injected water causes oscillation of pressure and flow in the blowdown loop steam generator since steam is generated from the water or alternately the water condenses steam when it flows through the steam generator. On the other hand, the water injected into the intact loop hot leg penetrates the core to the lower plenum maintaining its subcooling and cools fuel rods except several rods exposed to steam early by the injection initiation. However, the whole core is finally reflooded. After termination of accumulator injection, the water hold-up in the core decreases and portion of the core shows temperature rise again VI

9 JABRI-M until water hold-up recovers by LPCI injection and the core is reflooded. In the process of LPCI injection, a portion of the injected subcooled water into blowdown loop hot leg intermittently flows back into the upper plenum and causes violent condensation to result in repeated temporal rise of core water level. (3) Injection method of Run 505 (UPIS-upper plenum, ACC-lower plenum, ACC-lower plenum, LPCI-hot legs) The water accumulation in the core is not evidently increased directly by the UPIS injection. The whole core, however, is fully cooled by the injected water without sustaining exposure due to condensation effect. The effect of subsequent accumulator to UPIS is not clear since total amount of injected water from ACC was quite small. However, at least it can be said that exposure of fuel rods was not observed much. During LPCI injection, water accumulation rate was faster than the cold leg injection case and all rods were continuously cooled directly by falling water until reflooding. (4) Injection method of Run 507 (UPIS-upper plenum, ACC-cold legs with larger flow, LPCI-hot legs) Since the increase of accumulator flow rate was not enough, its injection did not contribute to water accumulation in the vessel and its suction effect of residual water by condensation appeared more dominantly. Thus early core exposure was resulted. However, both exposed region and risen temperature were relatively small since the injected UPIS water prior to ACC injection was drawn into the core. As the result of the draw-out of residual water, flashing in the lower plenum was weekened and fall down rate of LPCI water into the core became large leading to faster water accumulation rate than the case of Run 505. Fuel rods showing temperature rise was quenched not by reflooding with low density mixture but by falling water from the top. (5) Comparing fuel temperature behavior and other observed parameters, the best combination of ECCS injection among the four is combination (3) above followed by combinations (2), (4) and (1) in order. Effectiveness of ECCS using the three combinations except the reference combination (1) was experimentally verifitd with the ROSA-il facility as predicted. Application of the present conclusion to actual reactor should be made only after assessment of the system effect of the facility by a reliable analytical code. VII
