Engineering Experience

Nuclear Power Engineering
Madhumohan has significant credentials in the nuclear power industry of Canada, as the Responsible Design Engineer (RDE) for Class I & II power systems consisting of the power conversion equipment, DC switchgear and the battery banks, along with the safety-related critical loads to ensure uninterrupted power to the nuclear reactor under all normal, abnormal and accident conditions. He has successfully completed the new battery sizing calculations; short-circuit analysis, technical specifications, testing and maintenance procedures and installation of the replacement batteries as per the IEEE Standards and the Nuclear Safety Codes. He was instrumental in guarantying the continued safe operation of the four-unit Bruce-B CANDU nuclear power plant in Ontario, Canada, by effective engineering analysis, calculations and judgment applied to the aged nuclear-grade, last-line-of-defense battery system before its replacement, as per the CNSC regulations. Taking several breaks to pursue his music and musicological interests, he has continued in the nuclear power industry as an expert electrical design engineering consultant with significant contributions in the Bruce 1&2 Restart Project. Before joining the nuclear power industry, he worked in several other engineering firms in different areas in Canada. At one time, he even held both Microsoft Certified Systems Engineer (MCSE) and Novells’ Certified Network Engineer (CNE) certifications.

Technical Documents
Ontario Power Generation / Bruce Nuclear Power at Bruce-B, Ontario, Canada

• Nuclear-grade (class 1E) Battery Maintenance Manuals. Battery maintenance program was reassessed and revised per the IEEE 450 industry standard.
• Technical Specification for the replacement of the EPG batteries (in response to the SCR B-1999-05020). This was based on the revised duty cycle as specified in the new Design calculation (NK29-CALC-54300-00001). Seismic and Nuclear qualifications per the industry standards which were necessary but not included in the previous specification have been clearly specified.
• DCRs (416 & 417) were issued to correct drawings NK29-D3S-65437-6001-002 and –6002-002 to reflect the field reality concerning the 48 VDC supplies for the Boiler Steam Relief Valves (in response to the SCR B-2000-00384).
• Hydrogen gas estimation (of 211 hours before the hydrogen gas builds up to the allowable 2 % concentration) in the EPG battery rooms in case of ventilation failure. An electronic PAR was raised (in response to the SCR B-1999-05788).
• Technical explanation to show that the electrical equipment installations in the battery rooms that are adequately ventilated need not be of hazardous type (in response to the SCR B-1999-04270).
• Hydrogen gas build-up assessment in the SMR. It was shown to be safe, based on the calculations done per the IEEE standard and the Ontario Electrical Safety Code.
• CAP was submitted to resolve SCR B-2000-01151. This was to update the drawing NK29-EDN-66400-703-003 and the Flow Sheet, NK29-FXX-53520-0005-10.
• Technical explanation to declare the battery bank, BY11 healthy and thereby to enable continued safe operation of the 4-unit nuclear plant at Bruce B. This was in response to the TOE as a result of inoperability of the station battery bank BY12, 2000-06-30
• Black Start tests for the EPG and SG batteries conducted to acquire the latest data on the correct inrush currents so that the battery sizing could be verified and validated.
