'November 21, 1989, NRC INFORMATION NOTICE NO. 89-76: BIOFOULING AGENT: ZEBRA MUSSEL

Addressees

All holders'of operating licenses or construction permits for nuclear power

reactors.

Purpose

This information notice is intended to alert addressees to potential problems

related to biofouling of service water and cooling water systems that may

result from a recently identified biofouling agent, Dreissena polymompha

(zebra mussel). It is expected that recipients will review the ifnformation

for applicability to their facilities and consider actions, as this appropriate, to avoid similar problems. However, suggestions contained in information

notice do not constitute NRC requirements; therefore, no specific action or

written-response is required.-

Discussion:

The potential for biofouling has been of concern to the NRC since 1980heat because

IN 89-76 November 21, 1989 "The zebra mussel, Dreissena pokmorpha (Pallas), is a small mollusc native

to the Black, Caspin, and Azov Seas that was discovered in Lake Erie of the

Laurentian Great Lakes of North America in 1988. The mussel raises immediate

concerns for raw water users because it can obstruct the flow of water through

pipes, hoses, screens, and condensers when it occurs in substantial numbers.

Biofouling attributed to this mussel was observed at several power plants, water treatment plants, and processing and industrial facilities along Lake

Erie in 1989. At one power plant, densities as high as 700,000 per m2 were

observed in the intake canal in August. In addition, large numbers were found

in main steam condensers and in the service water system threatening operation

of cooling, fire protection, and dust suppression systems. Intakes of munici- pal water supplies along the Canadian and the United States shorelines have

also been impaired. In one southeast Michigan city, drinking water withdrawal

from Lake Erie was reduced 45% by the mussel."

The geographical area of immediate concern for this source of potential bio- fouling is along the Great Lakes and major tributaries and canals. This

potential is the subject of an international conference at Rochester, New York, on November 28 and 29, 1989. Additional information on the meeting may be

obtained from Charles R. O'Neill, Jr., of New York SeaGrant at (716) 395-2638 or Don W. Schloesser of the U.S. Fish and Wildlife Service at (313) 994-3331.

November xx, 1989 plants, and processing and industrial facilities along Lake Erie in 1989. At

one power plant, densities as high as 700,000 per m2 were observed in the intake

canal in August. In addition, large numbers were found in main steam condensers

and in the service water system threatening operation of cooling, fire protection, and dust suppression systems. Intakes of municipal water supplies along the

Canadian and the United States shorelines have also been impaired. In one south- east Michigan city, drinking water withdrawal from Lake Erie was reduced 45% by

the mussel (Griffiths, R. W., Kovalak, W. P., and Schloesser, D. W., "The Zebra

Mussel, Dreissena Polymorpha (Pallas, 1771), in North America: Impact on Raw

Water Users," Electric Power Research Institute Service Water System Reliability

Improvement Seminar, November 6-8, 1989).

Of major immediate concern is the potential fouling of water intake structures

in municipal, industrial, and power generation facilities. Fouling can result

in major flow restrictions. The geographical area of immediate concern is along

the Great Lakes and major tributaries and canals. This potential is the subject

of an international conference at Rochester, New York, on November 28 and 29, 1989.

Additional information on the meeting may be obtained from Charles R. O'Neill, Jr.,

of New York Sea Grant at (716) 395-2638 or Don W. Schloesser of the U.S. Fish

and Wildlife Service at (313) 994-3331.

The NRC issued GL 89-13 to resolve service water system problems affecting

safety-related equipment. GL 89-13 includes resolution of Generic Issue 51, Improving the Reliability of Open-Cycle Service Water Systems." Modes of

failure of the service water system addressed in the generic letter include

flow blockage from biofouling, sedimentation, and corrosion agents. To deter- mine appropriate surveillance and control measures for biofouling agents, all

species that may potentially cause flow blockage problems were included in the

scope of GL 89-13, which was not restricted to certain biospecies. The surveil- lance and control programs established in response to GL 89-13 are expected to

be sufficient to keep any blofouling agent, including Dreissena polymorpha, from

becoming a safety concern.
