The response to RAI # 7 is unresponsive to the request. In lieu of layout drawings as requested (consistent with Section 12.3.1 of Regulatory Guide 1.70), identify which of the following radiation protection facilities are common to Watts Bar Unit 1 and indicate whether they are sized and situated properly to support two operating units. The facilities are:
1

- 1. Controlled access areas,
- 2. personnel and equipment decontamination,
- 3. contamination control areas,
- 4. in plant traffic patterns to radiologically controlled areas,
- 5. health physics facilities (including dosimetry issue and maintenance, respiratory protection issue and maintenance, in-vivo and in-vitro bioassay, protective clothing and radiation survey instrument issue, Radiation Protection Manager and technical staff office/work space),
- 6. onsite laboratory for analysis of chemical and radiological samples, and
- 7. radiological counting room.
For each of these facilities not shared with Unit 1, demonstrate they are sized and situated properly to support Unit 2 operation.
