NRC Inspections of Power Operated Valve Programs

NRC

Source: Nuclear Regulatory Commission (NRC).

The Nuclear Regulatory Commission (NRC) is conducting detailed focused engineering inspections (FEIs) of power-operated valve programs at US nuclear plants as part of their Design Bases Assurance Inspection (DBAI) process. These inspections are rigorous and based on NRC Inspection Procedure 71111 Attachment 21N.02.

Dr. Kalsi, President and Founder, is an industry leader on valve programs, issues, troubleshooting, and regulatory interface with over 40 years of experience. Kalsi Engineering is author/principal investigator for over thirty EPRI publications on valve subjects, including the Performance Prediction Methodology (PPM) gate and butterfly valve model developers. Kalsi Engineering is actively involved in promoting technical leadership on valve issues with frequent MOV/AOV Users’ Group presentations, ASME committee membership, BWROG VTRG project contractor, and other technical forums.

With offices in Sugar Land, TX and Charlotte, NC, the Kalsi staff offers over 220 years of combined experience supporting valve programs and issues at nuclear plants and includes staff members that are former fleet and plant AOV/MOV program leads.
