Response to Open Item 9 1

TER Excerpt:

Certain test abstracts in FSAR Subsection 14.2.12 are - not classified as either SOV, P0, or IST tests, and hence the applicable test format, conduct, and review, evaluation, and approval mechanisms as described in FSAR Sections 14.2.3, 14.2.4, and 14.2.5, respectively, are unclear.

The applicable test format, conduct, and review, evaluat ion, and approval mechanisms should be provided for the following test abstracts (Amendment 11 modification):

Section Number Description 14.2.12.2.5 Core Load Neutron Detector Checkout 14.2.12.2.15 Initial Core Loading 14.2.12.2.17 Inverse Count Rate Ration Monitoring for Core Loading 14.2.12.8.11 Reactor Internals Vessel Inspection

Response

The activities described are net administratively controlled under the testing program. FSAR 14.2.10.1 will be revised as shown to briefly describe administrative control of activities discussed in FSAR 14.2.12.2.5, 14.2.12.2.15 and 14.2.12.2.17. The reactor internals inspection is discussed in FSAR 1.8 (Regulatory Guide 1.20) and FSAR S.9N.2.4. This inspection will be conducted by Westinghouse in a manner accepted by the NRC at similar facilities. Westinghouse will implement their NRC approved Quality Assurance Program in executing this task. Therefore, Section 14.2.12.8.11 will be deleted from the FSAR.

BVPS-2 FSAR 4 are installed, and additional mechanical and electrical tests are performed. The purpose of this phase of activities is to prepare the plant for nuclear operation and to establish that all design requirements necessary for operation are achieved. The core-loading and post-loading tests are described as follows:

14.2.10.1 Fuel Loading The reactor containment structure shall be completed, and containment integrity shall be established and maintained during fuel loading.

Fuel handling tools and equipment shall be checked, and dry runs conducted in the use of operation of equipment.

The reactor vessel and associated components will be in state'of readiness to receive fuel. Water level will be maintained above the bottom of the nozzles and recirculation maintained' to ensure a uniform boron concentration. Boron concentration can be increased via the residual heat removal system or directly to the open vessel.

The overall responsibility and direction for initial core loading is exercised by station management with technical assistance provided by Westinghouse.jp The overall process of initial core loading is, in neral, supervised from the operating floor of the containment structure by a licensed senior reactor operator with no other concurrent duties. Procedures for the control of personnel and l maintenance of containment integrity are established prior to fuel f)

Q lt3M M loading.

The as-loaded core configuration is specified as part of the core design studies conducted well in advance of fuel loading, and as such is not subject to change at start-up. In the event that mechanical damage is sustained during core loading operations to a fuel assembly of a type for which no spare is available onsite, an alternate core loading schene will be determined. Any such changes will be approved by appropriate DLC and Westinghouse personnel.

The core is assembled in the reactor vessel, submerged in primary grade water containing enough dissolved boric acid to maintain a calculated core effective multiplication factor (Kef f) of 0.90 or lower. The refueling cavity is dry during initial core loading.

Core moderator chemistry conditions (particularly boron concentration) are prescribed in the core loading procedures and are verified periodically by chemical analysis of moderator samples taken prior to and during core loading operations.

Core loading instrumentation consists of two permanently installed source range (pulse type) nuclear channels and two temporary incore source range channels plus a third temporary channel which can be used as a spare. The permanent channels are monitored in the main control room by licensed station operators; the temporary channels 7- s are installed in the containment structure and are monitored by

. l INSERT A Those activities described in Sections 14.2.12.2.5, 14.2.12.2.15 and 14.2.12.2.17 are accomplished jointly by Westinghouse and 1.c The Duquesne Light Company Beaver Valley Refueling Group and are not considered to be part of the testing program. These activities are subject to ,

administrative controls governing fueling activities. Procedures will be reviewed by the Duquesne Light Company Refueling Group, Duquesne Light Company Operations Quality Control and the Onsite Safety Comittee/ Procedures Review Committee. The procedures then will be ap-proved by the Plant Manager / designee.
