NEDO-24579-1 ABSTRACT This document provides unique definit .on of specific containment loading con-ditions that would result from a postulated loss-of-coolant accident in the Hope
! Creek Generating Station: Unit 1. Transient information is provided for con-tainment pressures and temperatures, vent system thrust, torus vertical loads, vent system pool swell impact loads, and vent header deflector loads. The docu-I ,
ment has been prepared under the Mark I Containment Program to aid Public Service Electric and Gas in the performance of a containment structural evaluation.

- 1. INTRODUCTION This report provides specific transient loading information resulting from a postulated loss-of-coolant (LOCA) accident in the Hope Creek Cenerating Station Unit 1. This report, in conjunction with the Mark I Containment Load Defini-tion Report, was prepared for Public Service Electric and Gas to use in the structural evaluation of the Mark I Containment system.
The f ollowing specific LOCA-related transient information is included o Pressure and temperature time histories for the drywell and wetwell e Vent system thrust loads e Net vertical pool swell loads and average submerged pressures on the wetwell e Pool swell impact and drag loads on the vent system I.
e Vent header deflector loads Transient information is presented via a series of figures for each of the above areas. An alpha-numeric identification scheme was developed for the figures: the alpha designation denotes the plant of interest; the first three digits of the numeric designation denote the applicable discussion section in the Mark 1 Containment Program Lead Definition Report (NEDO-21888).
Transient conditions presented in this report are results of plant unique test-ing and/or analysis for specific plant conditions that have been provided or requested by the aforementioned utility. Changes to those specific plant con-ditions could result in changes to the transient information reported herein.
If, af ter further review of this document, the responsible utility considers
! that such changes would be appropriate, the document can be modified accordingly.

This section provides the LOCA-induced pressure and temperature transients for the drywell and wetwell. The initial conditions for which the pressure and temperature responses were evaluated are also presented. Transient condi-tions are included for the design basis accident (DBA), intermediate break accident (IBA), and small break accident (SBA). The list of applicable figures and tables for this section is given on the following page.
Peak drywell pressure and temperature and the wetwell pressure and temperature at 30 seconds are identified on the DBA containment pressure and tempe'rature plots (Figures 4.1.1-1 and 4.1.1-2).
The peak containment pressures, the containment temperatures at the end of RPV blowdown, and the containment pressures and temperatures at the time of ADS initiation are identified on the IBA and SBA containment pressure and tem-perature plots (Figures 4.1.2-1, 4.1.2-2, 4.1.3-1, and 4.1.3-2).

SUMMARY
This document provides unique definition of specific containment loading conditions that would result from a postulated loss-of-coolant accident in the Hope Creek Generating Station: Unit 1. Transient information is provided for containment pressures and temperatures.
(
f, vent system thrust, torus vertical loads, vent system pool swell impact loads, and vent header deflector loads. The doctc.ent has been prepared under the Mark 1 Containment Program to aid Public Service Elec-tric and Gas in the performance of a containment structural evaluation.
