Enclosc o 1 Page :

ENCLOSURE I Use of Alternate Biocides in Service Water Systems Blofouling is a continuing item of concern at Northeast Utilities system generating stations. 'Especially trouhlesome is the problem of macrofouling, or invertebrate growth that causes blockage or flow reduction in condensers, heat exchangers, or safety-related water systems. Historically, biofouling problems have been most severe at marine or brackish-water installations, where Mytilus edulis (Blue Mussel) is the primary fouling organism.

At Millstone Nuclear Power Station, each of the three operating units has developed procedures to control mussel settlement and growth in both circu-lating and service weter systems. Although differing slightly in detail, procedures for each unit are similar. Mussels in the circulating water systems are controlled by periodic thermal backwash, or " mussel cooking";

heated water is. recirculated in' individual intake bays, with a temperature /

duration / frequency regime designed to kill mussels when they are small enough to pass through the system without causing difficulties.

The service water systems cannot be thermally backwashed; f 1ere are technical constraints that prohibit elevation of service water tempc"atures to levels that would kill mussels. Therefore, the Millstone un'ts have relied on continuous low-level chlorination (applied in the for m of sodium hypo-chlorite), to prevent mussel larvae, entrained in tha service water, from settling in system piping and components.

The continuous chlorination is adequate to prevent mussel settlement, but will not remove an established population. For example, if the chlorination system is' inoperable for a period of time that allows mussel settlement in service water piping, resumption of chlorination will not effect cleanliness of the fouled system. Cleaning of fouled service water systems at Millstone is accomplished primarily by waiting for attrition and mortality of mussels in the service water piping, then manually removing detached shells from the heat exchanger waterboxes. Obviously, this is an inefficient, time-consuming, labor-intensive procedure; Millstone has emphasized prevention of biofouling, rather than remediation, i.e., proactive vs, retroactive measures.

However, Millstone personnel are also investigating the possibility of using one of a number of nonoxidizing blocides, recently marketed by industrial chemical suppliers as molluscides. The most likely candidates at present are:

o Clam-Trol 1 (Betz Laboratories; active ingredients -

n alkyl dimethyl benzyl ammonium chloride and dodecylguanidine hydro-chloride),

o H-133A (Calgon; dodecylguanidine hydrochloride),

~

r ,q Enclosure 1 Page 2 o Bulab 6002 (Buckman Laboratories; sol y [ o xye t hyl e n e - ( d i me t hyl i m i n o ) -

ethylene-(dimethylimino)ethylenediciloride]),and o .Bulab 6009 (Buckman Laboratories;. 2-(thiocyanomethylthio) benzothiozole).

Material Safety Data Sheets for each product are attached.

However, since the use of any of these products would be necessary oniy after ,

exi n ing biofouling control procedures have failed, it is impossible to know a Triori where- or when such usage would be required, or the requisite appli-cation dose or concentration. Ideally, NUSCO would like to receive permission to release a . generic blocide from any of the circulating or service water discharges (Discharge Serial Nos. 001A, 001A-5, 0018 001B5, 001C, 001C-5), at a quantity / concentration to-be determined by vendor and NUSCO biologists. The situation would be analogous to a test application, with NUSCO committing. to conduct-sufficient-sampling, analyses, and toxicity testing to ensure environ-mental protection.

I Bulletin No. 3 25 H-133A MICROBIOCIDE DESCRIPTION H 133A Microblocide is a non oxidizing liquid, nitrogen based organic microbiocide for use in industrial systems. H 133A prevents growth of microorganisms encountered in industrial recirculati 1 cooling water systems.

ADVANTAGES

Effective over a broad pH range and is compatible with most other water treatment additives for scale, deposition and corrosion control.

Extremely effective for the control of sulfate reducing bacteria.

H 133A is a non oxidizing biocide which means that it is available for microbiological control rather than being consumed by inorganic reducing substances in the cooling water.

Protects cooling tower wood against fungal attack.

Non corrosive to cooling tower wood and system metallurgy at use concentrations.

l EPA REGISTRATION H 133A MicroblocIdo is registered by the Environmental Protection Agency (EPA Registration No.10445 3) as a blocide for use in industrial recirculating cooling water systems.

DIRECTIONS FOR USE Badly fouled syctems should be cleaned before initiating treatment. Begin treatment when system is in jeopardy of becoming affected or after cleaning systems whose efficiency is already impaired. Slug feed H 133A as received-do not mix with other chemicals. Do not overfeed.

TrGatment should be applied at cooling tower sump, suction side of recirculating pump, or any other point that assures good mixing with system water. Slug feetiing should be timed so that the entire oose is applied within a one hou' period, Recommended dosages allow for normal water loss due to evaporation, drift, and system blowdown and afford adequate contact time with organisms. Your Calgon Representative will provido technical assistanco in determining optimum dosages in relation to specific plant conditions or problems.

Initial Dose if system is noticeably fouled, slug feed 6.6 to 13.2 fluid ounces of H 133A per 1000 gallons of water in the system (50 to 100 mg/L). Repeat until control is achieved.

Subsequent Dose After bactorial controlis achieved, feed 3.3 to 6.6 fiuid ounces of H 133A per 1000 gallons of water in the systom (25 to 50 mg/L). Apply treatment two to three timos per week, or as needed to maintain control.

CONTRO'L TESTING i The best indication of the successful application of H 133A is visualinspection of tower surfaces or monitoring l changes in heat transfor or metal surfaces of process equipment.

PROPOSED BIOCIDE TREATMENT AND DISCHARGE This report addresses the proposed use of a biocide (trade name: Proxel GXL) at hiillstone Nuclear Power Station in Waterford, Connecticut. Proxel GXL is a 19G solution of 1,2-Benrisothiazolin-3-one (BIT) in aqueous dipropylene glycol.

Introduction hiillstone is proposing to use Proxel GXL to treat Radwaste hiaterial that has become chemically unstable due to microbial activity. hiore specifically, Ecodex resin waste (i.e.,

a predominantly cellulore based material) has been observed generating methane (CH4) pas. This production of methane gas has rendered the Ecodex waste unsuitable for burial as per 10CFR61.56 requirements. Subsequently, hiillstone has had to store Ecodex v ate shipping casks on-site for prolonged periods. This is an undesirable practice because of increased personnel exposure, increased costs (shielded storage containers), and potential safety hazards.

Proxel GXL was chosen as the administered biocide for the following reasons.

Low toxicity and minimal environmental impact.

It is non-oxidizing and should be chemically compatible with all system components.

lt can kill both aerobic and anaerobic baneria.

lt is used as a preservative and will provide sustained protection.

TestincWischarce Path The hiillstone Chemistry Department, working in conjunction with a professor from the University of Connecticut, has recently completed some initial experimentation concerning the effectiveness of the Proxel GXL biocide /biostat. This experimentation, although not conclusive, does indicate that the Proxel GXL biocide at a concentration of 2,200 ppm (WN) will significantly reduce the microbiological activity in an Ecodex waste liner.

l The following is a flow diagram for the disposition of the Proxel GXL. The concentration i

of 2200 pprn Proxel GXL and the initial volume of 200 gallons are conservative values.

Subsequently the final concentration of 7.02 pp/L Proxel noted in the Unit Al discharge i

water should not be exceeded. This will am be a one-time occurrence as it is anticipated to treat all future shipping casks containing Ecodex waste material (maximum of four shipping casks per year).
