Key Assets: Dauphin County is genuinely the site of the THREE MILE ISLAND ACCIDENT of March 28, 1979, the most serious accident in the history of the American commercial nuclear power industry; the accident occurred at the Three Mile Island Nuclear Generating Station, situated on an island in the Susquehanna River in Londonderry Township, roughly 10 miles downstream from Harrisburg; at approximately 4:00 AM – exactly one year to the hour after Unit 2 had become operational – an automatically operated valve in the reactor mistakenly closed, shutting off the water supply to the main cooling system; a combination of equipment malfunction, design-related problems, and operator error that followed caused the reactor core to partially melt down, releasing a small amount of radioactive gas into the atmosphere; for five tense days, engineers worked to bring the reactor under control while Pennsylvania Governor Dick Thornburgh weighed the possibility of ordering a mass evacuation of the surrounding area; the crisis unfolded just 12 days after the release of the fictional nuclear-disaster film “The China Syndrome,” intensifying national attention and public alarm; extensive follow-up studies by the Nuclear Regulatory Commission and other federal agencies found no detectable health effects among plant workers or nearby residents, but the accident’s psychological and political impact was profound – it triggered the immediate, though temporary, shutdown of several similar reactors nationwide, prompted a lengthy moratorium on new reactor licensing, and led utility companies to order no new nuclear plants in the United States from 1979 through the mid-1980s; cleanup of the damaged Unit 2 reactor took 14 years and cost roughly $1 billion; Unit 2 never reopened, though Unit 1 continued generating power for decades afterward before its own eventual closure; the accident led directly to sweeping, lasting reforms in reactor operator training, emergency response planning, and nuclear safety regulation across the entire US nuclear industry
Notes: The Three Mile Island accident’s genuine, extensively documented status as the most significant nuclear power accident in American history – including its far-reaching regulatory legacy – is presented here as established historical and scientific record.

About Dauphin County
Dauphin County is Pennsylvania’s eighth most populous county and the 237th most populous in the United States, covering 525 square miles of the Susquehanna River valley in central Pennsylvania.
Harrisburg (population ~50,000, the county seat and state capital) is Pennsylvania’s governmental center – the Pennsylvania State Capitol (completed 1906, designed by Joseph Huston in Italian Renaissance Revival style with a 272-foot dome larger than the US Capitol’s) anchors Capitol Hill overlooking the Susquehanna River. The Harrisburg riverfront and City Island park in the middle of the Susquehanna have been significantly developed for recreation. Harrisburg carries the legacy of the Three Mile Island nuclear accident (1979) – the most significant nuclear incident in US history – which occurred on an island in the Susquehanna River 10 miles from downtown.
Hershey (officially “Derry Township”) is one of the most extraordinary company towns in American history – founded entirely by Milton S. Hershey beginning in 1903 as the home for his chocolate manufacturing empire. The community includes Hersheypark (a major theme park), the Hotel Hershey (a National Historic Landmark resort), the Hershey Gardens, the Hershey Story Museum, and the Milton Hershey School – a boarding school for lower-income children endowed by Hershey’s entire fortune (~$17 billion today), arguably the largest philanthropic trust in the United States measured by assets.
Penn State Hershey Medical Center – the academic medical center of Penn State College of Medicine – is Dauphin County’s largest single employer, a Level I Trauma Center and major research institution that anchors the county’s healthcare economy.
Lower Paxton Township (population ~49,000) is the county’s most populous municipality – an unincorporated township with significant commercial development along Route 22 and residential communities serving state government workers.

Probate & Estate
Losing someone and having to deal with courts and paperwork at the same time is hard. This section won’t make that easier, but it should tell you what to expect, what it costs, and where to go – so at least you’re not walking in blind.
Where to go
Register of Wills, Dauphin County Dauphin County Courthouse, 101 Market Street, Room 103, Harrisburg, PA 17101 (717) 780-6500
Dauphin County is in south-central Pennsylvania, seated in Harrisburg – the Commonwealth’s state capital.
Step 1: figure out which path applies
Pennsylvania has NOT adopted the Uniform Probate Code. Probate runs through its own statute, the Probate, Estates and Fiduciaries (PEF) Code, Title 20 of the Pennsylvania Consolidated Statutes. Probate begins at the Register of Wills – an elected county official – in the county where the decedent lived. Routine, uncontested probate happens entirely at the Register of Wills; only disputes escalate to the Orphans’ Court Division of the Court of Common Pleas.
Small Estate Petition (20 Pa.C.S. § 3102) – available when the estate’s personal property (excluding real estate) totals $50,000 or less. This lets an interested party petition the Orphans’ Court directly for approval of a proposed distribution, skipping the need to formally open a full probate estate. Real property is never covered by this simplified process.
Formal Probate – required for estates exceeding $50,000 in personal property, or for any estate involving real property that needs to pass through probate. The Register of Wills validates the will (if any) and issues Letters Testamentary or Letters of Administration.
Step 2: filing for administration
The personal representative files with the Register of Wills in Dauphin County, along with the original will if one exists.
The Register of Wills reviews and, if in order, issues Letters Testamentary or Letters of Administration.
The personal representative gathers assets, notifies heirs and known creditors, and begins settling the estate.
Pennsylvania has a one-year creditor period running from the date of death, not from any published notice.
A Pennsylvania Inheritance Tax Return (REV-1500) must be filed with the Register of Wills, regardless of estate size.
Once debts, taxes, and expenses are settled, remaining assets are distributed according to the will or Pennsylvania’s intestacy laws, and the estate is closed.
What it costs
Filing fees vary; check with Dauphin County directly for current fees.
Pennsylvania has NO separate state estate tax, but its INHERITANCE TAX applies to virtually every estate: 0% to a surviving spouse (and to a parent inheriting from a child 21 or younger), 4.5% to children and other lineal descendants, 12% to siblings, and 15% to everyone else. No dollar exemption.
A 5% early-payment discount applies if paid within 3 months of death; the return and payment are otherwise due within 9 months.
