Report on EMI at APS Palo Verde Nuclear Generating Station

by | Mar 5, 2017 | Our Blog

Executive Summary

This is a report on the electromagnetic interference (EMI) measurements at Arizona Public Service Company (APS), Palo Verde Nuclear Generating Station conducted in 2013 as it relates to employees with an implanted medical device.   APS, Palo Verde Nuclear Generating Station requested a survey be done for electromagnetic field interference (EMI) with regard to the proper functioning of implanted medical devices, such as a cardiac defibrillator or pacemaker or an electronic insulin pump.  The electromagnetic field testing was done with the assistance of the Plant Safety Manager.

The diagram at the end of this document, “Diagram of All Areas Tested for EMI as Measured on March 15, 2013” shows those areas that exceeded heart device guidelines.

The following recommendations are made to enhance safety for employees with implanted medical devices:

  • Restrict Access: Limit access to high-EMI areas for employees with implanted medical devices. Implement clear signage and guidelines to ensure these employees are aware of the potential risks.
  • Shielding Measures: Install electromagnetic shielding in critical areas to reduce EMI levels. Shielding can be applied to walls, floors, and ceilings in high-EMI zones to contain and block electromagnetic fields.
  • Regular Monitoring: Conduct regular EMI monitoring to track changes in electromagnetic field levels over time. Periodic assessments will help ensure that EMI levels remain within safe limits and that new sources of interference are promptly identified and addressed.
  • Employee Training: Provide training for all employees on the potential risks associated with EMI and the proper use of personal protective equipment. Ensure that employees with implanted medical devices are fully informed about the areas to avoid and the measures in place to protect them.
  • Emergency Protocols: Develop and implement emergency protocols specifically for incidents involving EMI interference with implanted medical devices. These protocols should include immediate response actions and medical support procedures.
