SSiNS No.: 6835 IN 85-30
UNITED STATES
NUCLEAR REGULATORY COMMISSION
OFFICE OF INSPECTION AND ENFORCEMENT
WASHINGTON, D.C. 20555 April 19, 1985 IE INFORMATION NOTICE NO. 85-30: MICROBIOLOGICALLY INDUCED CORROSION OF
CONTAINMENT SERVICE WATER SYSTEM
Addressees
All holders of a, nuclear power reactor operating license (OL) or construction
permit (CP).
Purpose
This information notice is provided to alert recipients of significant corro- sion pitting due to microbiologically induced corrosion identified in stainless
steel piping sections of a service water system after an extended plant outage.
It is expected that recipients will review the information for applicability to
their facilities and consider actions, if appropriate, to preclude similar
problems occurring at their facilities. However, suggestions contained in this
information notice do not constitute NRC requirements; therefore, no specific
action or written response is required.
Description of Circumstances
On January 26, 1984, H. B. Robinson Unit 2 was shut down and remained shut down
throughout the year to replace the lower assemblies of the steam generator and
perform other maintenance work.
On November 19, 1984, Carolina Power and Light Company (CP&L) reported that
minor pinhole leaks were found in the heat affected zones of circumferential
welds joining 6-inch diameter, Schedule 10, 304 stainless steel piping that
provides service water to the four containment chilling units. Visual inspec- tion of the entire system revealed minor leakage at a total of 54 weld joints,
32 inside and 22 outside containment. Further radiographic examination re- vealed evidence of localized corrosion pitting on the inside surface at many
other austenitic piping weld joints of the system. Numerous sleeve assemblies
were required to restore integrity of the weld.s degraded by the corrosion
attack.
Discussion:
The licensee's investigation determined that the root cause of the problem was
the result of microbiologically induced corrosion (MIC). This is representa- tive of several similar incidents reported in construction and operating plants
in past years. A very recent example may be'a large number of leaking welds in
8504170240
IN 85-30
April 19, 1985 the Essential Spray Pond Piping System at Palo Verde Unit 2. The licensee's
evaluation is currently underway, but their preliminary conclusion is the
problem is caused by MIC.
MIC is a form of corrosive action that occurs as a direct, or indirect, result
of living organisms in contact with the materials of construction. Microorgan- isms have been observed in a variety of environments including soils, sediment, natural fresh water (e.g., wells, rivers, lakes), brackish and sea water, as
well as oil and other natural petroleum products. Many species may form
synergistic cross feeding support systems with other bacteria, fungi, algaes
and the like to enhance survival under the most adverse conditions. They have
been known to tolerate a wide-range of temperatures (-10 to 90 0 C), pH values of
0 to 10.5, oxygen concentrations from zero to almost 100 percent 02 and extreme
hydrostatic pressure. There are six different classifications of microorganisms
containing over 30 species that can be a problem, depending on the geographic
location and the environmental conditions.
The metabolic processes of organisms are sustained by chemical reactions.
These processes can significantly influence the corrosion behavior of materials
by (1) destruction of protective surface films, (2) creating corrosive deposits, and/or (3) altering anodic and cathodic reactions depending on the environment
and organism(s) involved.
Several general methods for inhibiting MIC have been employed with varied
degrees of success in recirculation systems. Among these methods were an
application of protective coatings in conjunction with cathodic protection, corrosion inhibitors, or water chemical treatment such as periodic shock
chlorination. However, it is important to correctly diagnose the presence of
MIC and the organisms involved before attempting such corrective measures to
ensure that no products are formed that themselves have a detrimental effect on
the materials. Moreover, if water chemical treatment is used, it is important
to ensure that residual chemical levels are maintained within the permissible
range of applicable EPA requirements.
Where the above measures are not practical, it has been observed that relative- ly rapid fluid flow tends to prevent attachment of organisms whereas low flow
rates or stagnant conditions favor biofouling and concentration cell corrosion.
Thus, cleaning and dry lay up, or periodic recirculation flushing, during
extencdd outages to mitigate know biological activity would appear to be
prudent alternatives.
