Abstract
On April 30, 2023, Hope Creek Generating Station (HCGS) completed a technical specification (TS) required shutdown because limiting condition for operation (LCO) 3.6.1.1, Primary Containment Integrity, was declared inoperable. LCO 3.6.1.1 was declared inoperable because drywell-to-torus differential pressure could not be established to perform surveillance requirement (SR) 4.6.2.1.f, and LCO 3.6.2.1, SUPPRESSION CHAMBER, could not be met. HCGS demonstrated containment Operability and returned to power operation.
HCGS will supplement this licensee event report (LER) when a root cause evaluation (RCE) is complete.

CAUSE OF EVENT
HCGS will supplement this LER when the RCE is complete.
SAFETY CONSEQUENCES AND IMPLICATIONS
There were no safety consequences because of this event. An engineering analysis determined that primary containment and the suppression chamber (torus) were capable of performing their intended safety functions. Therefore, per NEI 99-02, Regulatory Assessment Performance Indicator Guideline, Revision 7, this will not be counted as a safety system functional failure.
PREVIOUS EVENTS No similar LER or corrective action occurrences were found following a review of station LERs and the corrective action program for the past three years.
CORRECTIVE ACTIONS
HCGS identified bypass leakage through one torus-to-drywell vacuum breaker, completed repairs, satisfactorily performed SR 4.6.2.1.f, and returned to power operation on May 6, 2023.
HCGS will supplement this LER when the RCE is complete.
COMMITMENTS
There are no regulatory commitments in this LER.
