LOSS OF EMERGENCY ASSESSEMENT CAPABILITY
"This report is made for a loss of Emergency Assessment Capability associated with Emergency Action Levels for Toxic and Flammable Gas and is reportable under 10 CFR 50.72(b)(3)(xiii). During an emergency equipment inventory, it was identified that methods were not available to detect levels of toxic or flammable gas at the IDLH (Immediately Dangerous to Life and Health) level for a number of substances due to the detector having an unsuitable range. The IDLH is used to assess the Emergency Action Level Alert Range.
"The ability of the Control Room Staff to detect and respond to the presence of toxic or flammable gas is unaffected.
"Because there have been no chemical spills or releases that would require sampling to be performed, the health and safety of the public was not affected.
"The resident NRC Inspector has been notified."
The licensee will be notifying the state of Minnesota.
