14.3.1 Summary of Test Program and Objectives
Commonwealth Edison conducted a comprehe nsive test program following replacement of the Unit 1 steam generators that demonstrated that modified s tructures, systems, and components perform satisfactorily in service. The prin cipal objective was to provide assurance that the modification was properly designed and constructed and was ready to operate in a ma nner that would not endanger the health and safety of the public.
14.3.2 Organization and Staffing A team representing a cross-section of stati on, corporate, and vendor personnel managed and exe cuted the testing following replacement of the Unit 1 steam generators. The test program was established in accordance with the Quali ty Assurance Program as outlined in the QA Top ical Report refere nced in Chap ter 17.0.
The Quality Assurance activities related to the steam generator replacement project were the responsibility of Quality and Safety Assessment Department.
This included au dit and surveillance functions as well as other res ponsibilities related to 10 CFR 50, Appendix B, in accordance with t he Commonwealth Edison Quality Assurance Manual.
When required, v endors provided technical assistance during testing. The authority and responsibility of each organizational unit involved in the test program was as specified in the Quality Assurance Program.
14.3.3 Test Procedures Test procedures were developed using sta tion administrative programs. Individual test p rocedures specified prerequisites, data to be obtained, and requirements and ac ceptance criteria to be fulfilled. All t est procedures a nd results were reviewed and approved as required by the QA Topical Report.
14.3.4 Conduct of Test Program Tests were conducted u sing station administr ative programs. The test program was conducted using det ailed written procedures that included provisions for assuring that prerequisites have been completed. Data were examined as each test proceeded, and out-of-tolerance conditions were recorded and described in adequate
B/B-UFSAR 14.3-2 REVISION 7 - DECEMBER 1998 detail to permit post-test analy sis. Such data were evaluated during post-test review and resolved within the Quality Assurance program. 14.3.5 Review, Eval uation, and Approv al of Test Results Test results were reviewed a nd approved in a ccordance with station procedures and t he QA Topical Report.
14.3.6 Test Results The test procedures and test data are retained and maintained in accordance with the Quality Assurance pr ogram described in Chapter 17.0. The original test recor ds were reviewed for completeness, identified, and indexed to estab lish them as part of a permanent recor
- d. These records in clude data sheets completed during testing.
14.3.7 Conformance of T est Programs with Regulatory Guides Appendix A to the UFSAR identi fies those appli cable Regulatory Guides and describes the degree of c onformance to each.
14.3.8 Development of the Test Program The modification test pr ogram was developed ba sed on inputs such as the current l icensing basis requireme nts, the FSAR initial test program, procedures prepared for other util ities performing similar testing, and documents associated with the steam generator repl acement project.
A sequencing document was written to guide and c oordinate plant events and testing.
The document served as an interface procedure for mode, te mperature, and power changes to ensure requirements were me t prior to proceedin
- g. The procedure sequenced the modifica tion and surveillance testing necessary to return to full p ower following the outage.
14.3.9 Individual Test Description Test abstracts for i ndividual tests that wer e conducted following steam generator replacem ent are provided in Tabl es 14.3-1 through 14.3-16.
