This is misleading because it claims all safety systems responded the way they were supposed to. However the high pressure injection system was inoperable (although not called upon). This is how accident get started.

MANUAL REACTOR SCRAM DUE AFTER LOSS OF AN ESSENTIAL MOTOR CONTROL CENTER
"At approximately 0110 hours [EDT] on May 13, 2016, Susquehanna Steam Electric Station Unit Two reactor was manually scrammed by plant operators due to a sustained loss of AC power to essential plant loads. Power to MCC 2B246 was lost at 2355 on May 12, 2016, resulting in a loss of Drywell cooling. Drywell pressure increased to 1.3 psig when operators placed the mode switch to the shutdown position to manually SCRAM the reactor. All rods inserted as expected. Reactor water level lowered to -27 inches and was immediately restored by normal feedwater level control. Level 3 (+13 inch) PCIS isolations occurred, along with an initiation of the RCIC system (-30 inches). Once adequate level was verified, RCIC was overridden. Pressure was controlled with turbine bypass valves, and subsequently main steam line drains. All safety systems functioned as expected.
"The power loss also tripped Reactor Building HVAC, causing a loss of secondary containment differential pressure resulting in a loss of safety function.
"Due to the loss of drywell cooling, high drywell pressure actuations and a second reactor SCRAM signal, this signal was automatic, occurred at 0314 hours. HPCI [which automatically initiated on high drywell pressure] was subsequently overridden and declared inoperable, resulting in a loss of safety function. [HPCI did not inject into the vessel].
"The reactor is currently stable in Mode 3. Initial reports from the field indicate a phase to phase fault on the MCC 2B246 bus bars."
The licensee has notified the NRC Resident Inspector and will be issuing a press release.

NRC Proposes $7,000 Civil Penalty for Violation at West Virginia Manufacturing Facility
The Nuclear Regulatory Commission staff is proposing a $7,000 fine for an Atlanta-based company for a violation of agency requirements. The violation involves maintenance inappropriately done on a fixed nuclear gauge at the firm’s manufacturing facility in Fairmont, W.V.
Based on the results of an NRC inspection and investigation carried out at Novelis Corp.’s Fairmont plant, the agency is also issuing a Severity Level III violation to the company.
Novelis performs aluminum sheet and light-gauge fin/foil cold rolling activities at the facility. The company held an NRC license for the possession and use of fixed nuclear gauges at this location. The gauges are used to measure the thickness of the sheet metal products.
The NRC inspection and investigation completed on Jan. 21, 2016, determined that on Sept. 12 and 13, 2014, there was a violation involving the deliberate actions of plant employees. Specifically, an engineering reliability and automation engineer directed an electrical technician to repair nuclear gauge components related to the radiological safety of the device even though Novelis’ NRC license prohibits such activities.
“Our reviews found that the plant employees involved understood the work they were undertaking was not permitted, but they proceeded with the repairs nonetheless in order to minimize the economic impact on the facility from the inoperable gauge,” Acting NRC Region I Administrator
David Lew said. “These activities could have resulted in unnecessary radiological exposure and possibly physical harm. This enforcement action serves as an important reminder of the need for gauge owners and users to adhere to license conditions meant to ensure the proper handling of nuclear materials.”
In a March 8, 2016, letter, Novelis acknowledged the violation occurred, but it disagreed that the employees acted deliberately. After reviewing the information, the NRC staff concluded that the enforcement action was still appropriate. Based on the apparent economic incentive for the violation, the NRC used discretion to double the fine from base amount of $3,500.
Novelis has notified the NRC of prompt and comprehensive corrective and preventive actions in response to the issue, including the termination of its NRC license, which occurred on Jan. 12, 2016.
The NRC is also issuing a Severity Level III violation to the engineering reliability and automation engineer who authorized the technician to work on the gauge.
The company is required to respond to the violation and proposed civil penalty within 30 days.

DEP Reaches Natural Resource Damage Settlement with Talen Generation, LLC for 2005 Martins Creek Ash Spill
The Pennsylvania Department of Environmental Protection (DEP) and the Pennsylvania Fish and Boat Commission (PFBC) have entered into an agreement with Talen Generation, LLC, for the company to pay a total of $952,150.00 for natural resource damages associated with the August 2005 ash spill at the Martins Creek Steam Electric Station in Lower Mount Bethel Township, Northampton County. The fine money will be directed to mussel restoration and dam removal projects in tributaries to the Delaware River.
The spill occurred after a wooden stop log in the Ash Basin No. 4 discharge structure failed, causing an estimated 100 million gallons of ash material to spread across local fields and into the Oughoughton Creek and the Delaware River. DEP, working with PFBC, the Delaware River Basin Commission (DRBC) and the New Jersey Department of Environmental Protection (NJDEP), determined that the mussel population in the Delaware River was impacted as a result of both the spill and the cleanup. Mussel restoration and dam removal projects will assist in the restoration and vitality of the mussel populations and improve aquatic habitat and water quality.
