Procedures that control FWS chemistry, includes the SGs, condensate storage tank, FWS, condensate, main steam system, heater drain tanks, condensate demineralizer effluent, SG blowdown ion exchanger effluent, and condensate precoat filters.
These procedures control fluid chemistry in order to minimize the concentration of corrosive impurities (chlorides, sulfates, oxygen) and optimizes fluid pH. Control of fluid chemistry minimizes the corrosive environment for FWS components, and limits the rate and effects of corrosion/pitting, denting and SCC/IGSCC.
Secondary chemistry parameters (e.g., pH, dissolved oxygen levels) are measured at procedurally-specified frequencies. The measured parameter values are compared against target values that represent a goal or predetermined warning limit. If a measured value is out of bounds, corrective actions are taken (e.g., power reduction, plant shutdown) in accordance with the plant secondary chemistry procedure. Remedial actions are specified to minimize corrosion degradation of components and to ensure that secondary system integrity is maintained.

5.7 DFO DFO TKs Crevice Corrosion, General Corrosion, Pitting, Fouling, and MIC DFO (Tanks and Chemistry)
See Section 16.2.16 for a general description.
Under the DFO Storage Tank Water Check STP, water that may collect at the DFO tank bottom is periodically drained and fuel chemistry is analyzed. If the amount of drained water or fuel chemistry is found not to meet the established standards, corrective action is implemented as required. Draining the water will minimize the degradation of the internal surface of the carbon steel tank bottom, and will also minimize the possibility of MIC since microbes require water to survive and multiply. If more than one gallon of water is drained, the operator is required to notify the shift supervisor, and the situation will be investigated to determine and correct the source of the water.

See Section 16.2.16 for a general description.
Fuel oil chemistry is controlled, under this procedure, including testing for the presence of biologics. The procedure establishes surveillance frequencies, fuel oil specifications (e.g., viscosity, %
water and sediment, particulate contamination, and biologics), and corrective actions. Sampling and analysis are performed on new fuel prior to unloading from fuel trucks. This procedure specifies limits for viscosity, water, and sediment for both receipt inspection and Technical Specification surveillance, in accordance with ASTM D975-81. This procedure requires the addition of a stabilizer/corrosion inhibitor prior to unloading fuel oil into the Fuel Oil Storage Tanks (FOSTs). This approach provides assurance that the desired ratio of inhibitor to fuel oil exists. Corrosion inhibitor is added to the fuel to control corrosion of any exposed metal surfaces in the tank. A biocide is also added to the FOSTs for the initial addition, or if the presence of biological activity has been confirmed, to control MIC.

5.7 DFO DFO TKs Crevice Corrosion, General Corrosion, Pitting, Fouling, and MIC DFO (Tanks and Chemistry)
See Section 16.2.16 for a general description.
Draining water and chemistry testing/control of fuel oil provide a high degree of confidence that the effects of the plausible ARDMs will be minimized. However, the internal surfaces of the tank are not accessible during system walkdowns. Calvert Cliffs has developed PM Tasks to perform internal inspections of the FOSTs at periodic intervals, consisting of UT assessments of the condition of the tank interior conducted in accordance with American Petroleum Institute Standard 653 for FOST inspections. The results of these inspections are documented as part of the PM program.
These results are used to assess the overall condition of the tank interior and to determine the appropriate intervals for future inspections.

5.8 EDG Jacket water expansion TKs and cooling water PP General Corrosion, Crevice Corrosion, and Pitting Chemistry See Section 16.2.12 for a general description.
Procedures are credited with mitigating the effects of general corrosion, crevice corrosion, and pitting of the cooling water piping and jacket water expansion tanks by monitoring and maintaining EDG jacket water chemistry (e.g., pH, dissolved oxygen). This procedure contains two different sets of chemistry parameters, one for the Fairbanks Morse EDGs, and one for the Societe Alsacienne De Constructions Mecaniques De Mulhouse EDG. The water is treated with hydrazine or corrosion inhibitors to minimize the amount of oxygen in the water, which aids in the prevention and control of most corrosive mechanisms. Continued maintenance of system water quality will mitigate EDG jacket water expansion tank and cooling water piping degradation. The procedure provides for a prompt review of EDG jacket water chemistry parameters so that steps can be taken to return chemistry parameters to normal levels, and, thus, minimize the effects of general corrosion, crevice corrosion, and pitting.

5.8 EDG DFO day TKs, drip TKs and associated level switches General Corrosion, Crevice Corrosion, Pitting, and MIC DFO (Tanks and Chemistry)
See Section 16.2.16 for a general description.
A procedure is credited for mitigating the effects of crevice corrosion, general corrosion, MIC and pitting on the interior surfaces of the EDG DFO day tanks, and drip tanks with associated tank-mounted level switches. Under this procedure, fuel oil chemistry is controlled, including testing for the presence of biologics. The procedure establishes surveillance frequencies, fuel oil specifications (e.g., viscosity, % water and sediment, particulate contamination and biologics), and corrective actions. Sampling and analysis are performed on new fuel prior to unloading from fuel trucks. This procedure specifies limits for water, viscosity, and sediment for both receipt inspection and Technical Specification surveillance for fuel oil in the FOSTs in accordance with ASTM-D975-81. The procedure currently has target values and action levels that give an acceptable range or limit for a given parameter.
This procedure now requires the addition of a stabilizer/corrosion inhibitor prior to unloading fuel oil into the FOSTs. This approach provides a better assurance that the desired ratio of inhibitor to fuel oil exists. This procedure was revised to incorporate criteria in accordance ASTM-D270-65 for taking quarterly samples from the diesel FOSTs. This revision involves taking multilevel samples from each diesel FOST rather than sampling only from the tank bottom.

The procedures provide for periodic draining of DFO day tank of any water that may be present, which minimizes the corrosive effects of water on carbon steel. The tank sample is taken and visually examined for the presence of water in the fuel. This procedure is currently performed monthly after the EDGs are shut down from testing.

5.17 SRW PUMPs General Corrosion, Crevice Corrosion and Pitting PM See Section 16.2.23 for a general description.
The SRW pumps are inspected for general corrosion, crevice corrosion/pitting using the PM Pump Overhaul Procedure. This procedure instructs the user to inspect certain pump components for erosion, wear, and mechanical damage. The procedure has been modified to include inspections for general corrosion, crevice corrosion/pitting on the pump casing and bushings. The procedure directs the user to contact the System Engineer if any of these indications are found, and to replace parts as necessary.
229b.
5.17 SRW PUMPs General Corrosion, Crevice Corrosion and Pitting Surveillance Testing See Section 16.2.30 for a general description.
Pump inspections rely on the SRW pump periodic test of the pump active function (flow vs. head) to trigger the overhaul. The periodicity of these tests is established by Technical Specifications.
