U. S. NRC Regulation Guide 1.52 regulating ESF ACS in nuclear power plants has been revised to revision 3. To apply reduction of operability test time, allowance of alternative challenge agents for in-place leak test of HEPA filters, and upgrade of Methyl Iodide penetration acceptance criterion in activated carbon performance test suggested in Reg. Guide 1.52(Rev.3) on Yonggwang units 5 and 6 ESF ACSes, technical feasibility study was carried out with on-site experiments as well as experiments with a lab-scale model. It was confirmed that the moisture in the system returned to the level before the test in 1 or 4 days even though the moisture was removed during the operability test lasting more than 10 hours. Therefore, it is appropriate to perform monthly operability test in 15 minutes just long enough to check the operability of equipment. To change challenge material for in-place HEPA filter leak test, size of aerosol, production rate, and leak detection capability were compared for DOP and PAO. It was concluded that PAO can be substituted for DOP in nuclear power plants. The upgrade of Methyl Iodide penetration acceptance criterion from 0.175 % to 0.5 % in active carbon filter bed deeper than 4 inches was to conform to the change of activated carbon performance test method to ASTM D3803(1989). It was confirmed that Methyl Iodide penetration acceptance criterion of 0.5 % under $30^{\circ}C$, relative humidity 95 % condition was conservatively good enough for testing performance of active carbon insitu. The licence change of Yonggwang units 5 and 6 has been completed based on this study.

A nuclear plant ESF ACS simulator was designed, built, and verified to perform experiment related to ESF ACS of nuclear power plants. The dimension of 3D CAD model was based on drawings of the main control room(MCR) of Yonggwang units 5 and 6. The CFD analysis was performed based on the measurement of the actual flow rate of ESF ACS. The air flowing in ACS was assumed to have $30^{\circ}C$ and uniform flow. The flow rate across the HEPA filter was estimated to be 1.83 m/s based on the MCR ACS flow rate of 12,986 CFM and HEPA filter area of 9 filters having effective area of $610{\times}610mm^2$ each. When MCR ACS was modeled, air flow blocking filter frames were considered for better simulation of the real ACS. In CFD analysis, the air flow rate in the lower part of the active carbon adsorber was simulated separately at higher than 7 m/s to reflect the measured value of 8 m/s. Through the CFD analyses of the ACSes of fuel building emergency ventilation system, emergency core cooling system equipment room ventilation cleanup system, it was confirmed that all three EFS ACSes can be simulated by controlling the flow rate of the simulator. After the CFD analysis, the simulator was built in nuclear grade and its reliability was verified through air flow distribution tests before it was used in main tests. The verification result showed that distribution of the internal flow was uniform except near the filter frames when medium filter was installed. The simulator was used in the tests to confirm the revised contents in Reg. Guide 1.52 (Rev. 3).

Background: The efficacy of tumescent liposuction in the treatment of axillary osmidrosis has been widely established. But there have been few studies that have conducted a comparative analysis according to the level of dermal curettage with respect to the efficacy and safety. Objective: The aim of this study was to evaluate the clinical efficacy and complications of tumescent liposuction according to the degree of dermal curettage. Methods: From September 2004 through August 2009, a total of 33 patients with axillary osmidrosis (66 axillae) were included in this study. Twelve patients (24 axillae) were treated by tumescent liposuction with dermal curettage at the level of the mid-dermis (the classical technique group), and the other 21 patients (42 axillae) were treated by tumescent liposuction with dermal curettage at the level of the dermo-subcutis junction (the modified technique group). The preoperative and postoperative disease severity was measured as 0, 1, 2 and 3. The improvement of symptoms was graded by the patient as excellent, good, fair and poor. We also evaluated the postoperative complications, including skin necrosis, scar, hematoma, sensory disturbance and infection. Biopsies of the axillary skin were performed in 7 patients to confirm the level of dermal curettage and the reduction of apocrine glands after treatment. Results: The follow-up ranged from 6 to 60 months. Six months after treatment, 95.8% (23/24) of the axillae in the classical technique group and 95.2% (40/42) of the axillae in the modified technique group had reduced disease severity below 1. Among the 12 patients treated with the classical technique, 11 (91.7%) had excellent to good results, while 95.2% (20/21) of the patients treated with the modified technique had excellent to good results by the patients` own grading. The complications included skin necrosis, scar and hematoma. In the classical technique group and the modified technique group, the incidence of skin necrosis was 12.5% (3/24) and 2.4% (1/42), respectively, the incidence of scar formation was 4.2% (1/24) and 0%, respectively, and the incidence of hematoma was 8.3% (2/24) and 0%, respectively. The postoperative histologic examinations confirmed that the dermal curettage level was at the mid-dermis in the classical technique and at the dermo-subcutis junction in the modified technique. Interestingly, the histologic examination from the classical technique group revealed vacuolar alteration of keratinocytes and partial separation of the dermo-epidermal junction. Conclusion: The efficacy of the modified technique is compatible with that of the classical technique, but the modified technique offers fewer complications. So, the modified technique may improve the cosmetic outcome without reducing the treatment efficacy for the patient with axillary osmidrosis. (Korean J Dermatol 2010;48(9):741~748)
