IE Information Notice No. 80-09 POSSIBLE OCCUPATIONAL HEALTH HAZARD ASSOCIATED WITH CLOSED COOLING SYSTEMS FOR
OPERATING POWER PLANTS
As a result of information that the causative agent for meningoencephalitis, the amoeba Naeglaria fowleri, had been found in warm water ponds in Florida
and Texas where two fatalities were reported, NRC initiated a study by Oak
Ridge National Laboratory on the occurrence of Naeglaria in power plants with
closed cycle cooling systems. For seven power stations examined (6 fossil,
1 nuclear), this study confirmed the presence of pathogenic Naeglaria at three
plants including the nuclear plant (Dresden).
Recently, Northern States Power Company (NSP), while monitoring the Prairie
Island Nuclear Generating Plant closed cooling system for the amoeba, did
identify the presence of Naeglaria. Although the Minnesota Department of
Health does not consider the existence of the organism to be a public health'
threat, it was recognized as a possible occupational health hazard. Plant
personnel.were instructed to wear-rubber gloves when coming into contact with
the circulating water and to wear respirators when working in the area of the
cooling towers. In November 1979, NSP conducted a special chlorination
program at Prairie Island that was designed by Dr. Richard Tyndall of Oak
Ridge to eradicate this organism. Chlorine concentrations in the circulating
water system was raised to 2.0 mg/1 (measured as free chlorine) for a period
of six hours to destroy both the amoebae and its encysted form. This program
also included dechlorination prior to discharge and intensive monitoring to
document chlorine concentrations, the impacts of chlorinated cooling tower
draft and sampling to determine the efficacy of the special chlorination
program in destroying Naeglaria. Preliminary results indicate that the
program was successful in reducing the number of organisms present by two to
three orders of magnitude.
It is recognized that there have been no reported cases of meningoencephalitis
reported among power plant personnel to date; however, the seriousness of the
disease (if contracted) and the confirmed presence of Naeglaria at four plants, leads us to inform all licensees with closed cycle cooling water systems of
the potential occupational hazard and advise that they take appropriate action.
No written response to this IE Information Notice is required. If you desire
additional information regarding this matter, contact the Director of the
appropriate NRC Regional Office.
