Diablo Canyon Verification P.3 )

PROJECT DESCRIPTION

1. OBJECTIVE OF PROPOSED WORK

a. Background )

On September 28, 1981 PG&E reported that a diagram error had been found in a portion of the seismic qualification of the Diablo Canyon Nuclear Power Plant, Unit 1 (DCNPP-1). . This error resulted in an incorrect application of ~ the seismic floor response spectra for sections of the annulus of the Unit 'l containment building. The error originated when PG&E transmitted a sketch of Unit 2 to a consultant. This sketch contained Unit 2 opposite hand geometry incorrectly identified as Unit 1 geometry.

As a result of, this error, a seismic reveri,fication program was established to determine if the seismic qualification of the plant was adequate for the pos tulated Hosgri 7.5M earthquake. The Commission issued an order suspending license CLI-81-30 for fuel load and low power tests up to 15% of rated power at DCNPP-1. This suspending order also specified that an Independent Design Verification Progran (IDVP) be conducted to assure that the plant met the licensing criteria. The IDVP program is currently underway and producing Interim Technical Reports (ITR) on the work as it progresses.

b. Objective The objective of this work is for BNL to independently analyze for NRC/SQbB l Diablo Canyon Power Plant annulus steel structure and the buried diesel oil tanks for the seismic loads imposed by the Hosgri event. Furthermore, BNL will also provide the NRC/SGEB staff with expertise in the field of seismic analyses

'to carry out reviews and audits of the work currently underway at the IDVP and P G&E. BNL will also attend technical interchange meetings for the Diablo Canyon license restoration work. Finally, BNL will assist the staff in evaluating the stnictural integrity of Unit 2 structures and Unit 2 specific allegations.-

SUMMARY

OF PRIOR EFFORTS Under Fin No. A-3377, BNL carried out similar work for NRC with respect to independent derivations for the Diablo Canyon Annulus Structure Vertical Floor /

Spectra. The BNL staff, especially, the senior members are highly familiar with all aspects of structural dynamic response analysis, having derived some of the analysis methods currently employed by engineers in the civil / structural area.

3. WORK TO BE PERFORMED AND EXPECTED RESULTS L a. Work Requirements With respect to the Diablo Canyon evaluation and verification work to be carried out under this program, thirteen specific tasks will be performed. These are:
