Cooper Nuclear Station and What It Means for Your Health

Cooper Nuclear Station sits on the Missouri River in Brownville, Nemaha County, Nebraska. Owned and operated by the Nebraska Public Power District (NPPD), the facility began commercial operations in July 1974—precisely the era when asbestos-containing materials were standard in industrial construction across the United States.

Workers at Cooper Nuclear Station may have been exposed to asbestos-containing materials during construction, routine maintenance, or refueling outages. Asbestos causes mesothelioma, asbestosis, and other serious diseases that may not manifest until 20 to 50 years after exposure.

Insulators, pipefitters, boilermakers, electricians, and maintenance crews reportedly worked with or near asbestos-containing materials for decades. Former employees and their families who have since been diagnosed with mesothelioma, asbestosis, or other asbestos-related diseases may have legal rights—even when exposure occurred decades ago.

Facility Overview: Construction, Operations, and Outage Cycles

Location and Scale

Cooper Nuclear Station covers approximately 1,060 acres along the Missouri River in Nemaha County and generates roughly 830 megawatts of power. The facility is named after John Graham Cooper, a former NPPD president.

Outage Cycles Drive Exposure

The plant employs hundreds of permanent workers and brings in thousands of additional contractor employees during refueling and maintenance outages every 18 to 24 months. Outage periods are when asbestos-containing materials were most actively disturbed, handled, and removed—creating the highest exposure risk for contract workers and permanent staff alike.

Key Historical Periods

Late 1960s – Early 1970s: Construction Phase

Industrial asbestos use was at its peak in the United States during this window. Materials used to insulate, fireproof, and seal the facility’s systems reportedly contained asbestos-containing materials. Construction workers, tradespeople, and laborers across all disciplines may have been exposed.

1974 Onward: Commercial Operations

From the first day of commercial operation, ongoing maintenance involved regular handling of aging asbestos-containing materials throughout the facility’s systems.

1970s–1980s: Outage Seasons and Contract Worker Influx

Outage crews rotated through on predictable schedules. Contract workers—many of them traveling tradespeople working at multiple nuclear plants—reportedly worked alongside permanent staff in heavily insulated areas. Insulators, pipefitters, and boilermakers faced the heaviest exposure during this period. If you worked multiple nuclear plant outages, cumulative asbestos exposure Nebraska and across state lines may strengthen your claim.

1980s–1990s: Abatement Work

Regulatory requirements increased to remediate or encapsulate asbestos-containing materials at nuclear facilities. Partial abatement created its own secondary exposure hazard. Workers who performed abatement activities may have faced uncontrolled fiber release if proper containment protocols were not in place.

Present Day: Legacy Materials

Modern regulations govern asbestos handling, but legacy materials may still be present in older sections of the facility. Not all encapsulated systems have been fully replaced.


Powerhouse Equipment at Cooper Nuclear Station

Cooper Nuclear Station operates a boiling water reactor system. The facility’s thermal systems were designed and installed during the peak asbestos integration period—late 1960s through 1974.

Documented powerhouse systems include:

  • Primary coolant loops and secondary loop piping—extensively insulated with pipe covering and block insulation during construction.
  • Main turbine and associated thermal systems—driving the electricity generation process.
  • Condenser systems and heat exchangers—requiring heavy thermal insulation throughout.

All major equipment surfaces, flanges, gaskets, and pipe runs were reportedly insulated or sealed using materials documented in the AsbestosIndex Product Crosswalk—the authoritative reference for asbestos-containing materials used in powerhouse equipment during this era.

For a complete list of specific asbestos-containing products documented for boiling water reactor construction of this period, consult the AsbestosIndex Product Crosswalk.


Why Asbestos Was Built Into Nuclear Power Plant Design

A boiling water reactor like Cooper’s uses nuclear fission to heat water, produce steam, and drive turbines. That process generates extreme thermal and pressure demands:

  • High temperatures throughout primary and secondary loops.
  • High-pressure steam lines running through the turbine building and reactor building.
  • Miles of pipe requiring thermal insulation to maintain efficiency.
  • Electrical systems requiring fireproofing in cable trays, conduits, and panel boxes.
  • Pumps, valves, flanges, and expansion joints requiring gasketing and packing materials.

From the early twentieth century through the mid-1970s, asbestos was the standard engineering solution to every one of these problems. It was abundant, inexpensive, thermally resistant, chemically resistant, and fire-resistant—and no commercially available material matched its performance profile. Nuclear power plants built during the 1960s and 1970s, including Cooper Nuclear Station, were constructed with asbestos-containing materials reportedly integrated into virtually every major building system.


Asbestos-Containing Materials Allegedly Present at Cooper Nuclear Station

Based on the construction era, the facility type, and patterns documented at comparable boiling water reactor plants built during the same period, the following categories of asbestos-containing materials were allegedly present at Cooper Nuclear Station:

Thermal Pipe Insulation

The most pervasive material category at any nuclear plant. Steam lines, feedwater lines, condensate return lines, and high-pressure piping throughout the turbine building were insulated during construction. Cutting, breaking, or disturbing this insulation—as workers did routinely during outage work—released respirable fibers into the air. Exposure was continuous during maintenance seasons.

Block Insulation

Large-diameter pipes, vessels, tanks, and heat exchangers were covered with block insulation during the construction era. Insulators and pipefitters disturbed this material repeatedly during maintenance outages.

Insulating Cement

Used to fill joints between block insulation sections and around irregular surfaces. Mixed on the job site, generating substantial dust. A documented exposure source at facilities of this era.

Refractory Materials

High-temperature vessels and associated equipment reportedly contained asbestos-containing refractory materials during the plant’s early operational years.

Gaskets and Packing Materials

Valve bodies, pump flanges, heat exchangers, and pipe joints throughout the plant required gasketing and packing. Workers scraped and ground off old gaskets during maintenance—a process that releases airborne fibers. Pipefitters and boilermakers performed this work routinely.

Spray-Applied Fireproofing

Structural steel in the turbine building and other structures may have received spray-applied fireproofing during construction. This was standard practice for large industrial construction through the early 1970s.

Floor Tiles and Adhesives

Vinyl floor tiles and the mastics used to bond them reportedly contained asbestos-containing materials during the construction era. Present throughout administrative, operations, and control room areas.

Electrical Cable and Conduit Insulation

Nuclear facilities contain large quantities of electrical cable. Cable insulation and conduit joint compounds used during the construction era may have incorporated asbestos-containing materials. Electricians who pulled wire, terminated cables, or worked near disturbed cable runs may have been exposed.

Thermal Textiles and Protective Pads

Cloth, blankets, and rope packing used as removable insulation jackets and protective covers on hot equipment were common throughout industrial facilities of this era and may have contained asbestos-containing materials.


Occupational Trades with Elevated Exposure Risk

Insulators (Heat and Frost Insulators)

Heat and Frost Insulators members reportedly performed work at Cooper Nuclear Station during construction and outage seasons. The trade applied, maintained, and removed thermal insulation systems throughout the facility’s life. Removing old asbestos-containing pipe covering and block insulation ranks among the highest-dust-generating activities at any industrial site. Insulators who worked at Cooper during construction or outage seasons in the 1970s and 1980s may have faced repeated inhalation exposure. If you are an insulator diagnosed with mesothelioma, an asbestos attorney Nebraska can evaluate your exposure history and filing options.

Pipefitters and Steamfitters

Plumbers and Pipefitters union members and other regional pipefitters reportedly worked at Cooper Nuclear Station, installing, maintaining, and repairing miles of process piping. The work required breaking into insulated pipe systems, removing gasketing materials, and working in close proximity to disturbed insulation. Scraping and grinding old asbestos-containing gaskets is a well-documented exposure pathway.

Boilermakers

Boilermakers union members reportedly performed equipment maintenance and construction-phase work at Cooper Nuclear Station on reactor pressure vessels, heat exchangers, condensers, and high-pressure equipment. They handled refractory materials, gaskets, and packing materials directly and worked in confined spaces where asbestos fiber concentrations could reach dangerous levels with limited ventilation.

Electricians

Electricians worked throughout the facility pulling wire, installing conduit, and maintaining electrical systems—frequently sharing spaces with insulators and pipefitters who were actively disturbing asbestos-containing materials. Bystander exposure from adjacent trades is a recognized and documented hazard. Direct handling was not required to sustain a claim.

Millwrights and Mechanics

Worked on turbines, pumps, and rotating equipment. Regularly encountered asbestos-containing packing and gasket materials. Pump rebuilding and valve repacking generated asbestos dust as routine tasks.

Construction Workers (All Trades)

Carpenters, laborers, ironworkers, and painters who worked during the late 1960s and early 1970s construction phase shared spaces where asbestos-containing materials were being cut, fitted, and applied. Exposure did not require direct handling of insulation or gaskets.

Outage Contract Workers

Nuclear power plants rely heavily on contract workers during refueling outages. Workers who traveled between facilities accumulated exposures at multiple sites. If Cooper Nuclear Station was part of your outage circuit—even for a single season—you may have been exposed to asbestos-containing materials there. Cumulative exposure across the nuclear industry is a recognized legal and medical factor in these cases.


Family Members: Take-Home Exposure and Secondary Diseases

How Para-Occupational Exposure Occurs

Workers were not the only ones at risk. Take-home exposure—also called para-occupational exposure—occurs when workers carry asbestos fibers home on their work clothing, hair, skin, and equipment. Family members who laundered work clothes, greeted workers at the door, or shared living space with someone who worked at Cooper Nuclear Station may have been exposed to asbestos-containing materials without ever setting foot on the job site.

Who Was at Risk in the Household

  • Spouses and domestic partners who laundered contaminated work clothing—shaking out, washing, and drying heavily soiled garments releases fibers directly into home air.
  • Children who came into physical contact with a parent still wearing work clothes, or who played in areas where contaminated gear was stored.
  • Other household members who shared space with an industrial worker during the high-exposure decades.

Mesothelioma diagnosed in a family member who never worked at Cooper Nuclear Station may still be traceable—legally and medically—to asbestos-containing materials brought home from the facility. These cases are viable and have resulted in significant jury verdicts and trust fund recoveries.


Personal Injury Claims

If you have been diagnosed with mesothelioma, asbestosis, lung cancer, or another asbestos-related disease, you may file a personal injury lawsuit against the manufacturers of asbestos-
