Chemistry specifications which are not included in the SGOG guidelines shall meet or exceed the Nuclear Steam System Supplier (NSSS) vendor recommendations (References 3.3 and 3.4). Specific chemistry specifications for critical chemistry control parameters under full power operating conditions are listed in Attachment 8.A.
6.1.2 Station procedures shall identify specific corrective actions and/or power reductions / holds to be initiated upon exceeding station secondary water chemistry specifications including the sequence and timing of such corrective actions. These actions shall be based on the corrective actions recommended in the SGOG Secondary Water Chemistry Guidelines and NSSS vendor recommendations, as applicable. Corrective actions specified in the procedures shall include power reductions as specified in Attachment 8.A.
6.1.3 Chemistry specifications and/or corrective actions in addition to or more stringent than the guidelines referenced in Section 6.1.1 shall be instituted on a
- plant-specific basis. These specifications and
' corrective actions may be instituted directly by station chemistry or as recommended by Nuclear Materials and Chemistry. These specifications and corrective actions shall be based on specific concerns related to known corrosion phenomena and/or recent industry experience.
Specifically, steam generator inspection / examination results shall be evaluated to determine if any additional secondary water chemistry controls are needed. The specifications shall also be based on a NEO 2.17 Rev. O Date: 5/30/85 Page 5 of 11
proven capability to maintain a parameter at significantly lower levels than those specified in the referenced guidelines. .
6.1.4 Exceptions to the guidelines specified in Sections 6.1.1 through 6.1.3 shall be noted in the Management Status Report on Water Chemistry, as described in Section 6.6.
6.1.5 Exceeding Chemistry Specifications 6.1.5.1 Upon exceeding a chemistry specification, the correct personnel shall be notified and corrective actions taken, including power reductions / holds, as described in Figure 7.1.
6.1.5.2 Station and corporate personnel shall l identify alternates to carry the responsi-l bility and authority identified in Figure 7.1 l in their absence.
6.1.5.3 When not on site, key station and corporate personnel identified in' Figure 7.1 shall be available for contact. This availability may be achieved by being at an established telephone number or by carrying a paging device. When these choices are not feasible, an alternate must be identified per Section 6.1.5.2.
6.1.5.4 If an action level condition occurs (or threatens to occur) which requires a power reduction / hold, and extreme or unusual circumstances occur which provide technical justification for not reducing or holding power, an exception to the action level requirements may be applied for. To obtain an exception from the action level require-ments, technical justification must be provided which indicates that circumstances exist which were unforeseen or unaccounted for in the guidelines referenced in Sec-tion 6.1.1. Exceptions from the action level. requirements, which are technically justified, must receive the prior approval of the Station or Unit or Station Services Superintendent, and the Manager of Nuclear Materials and Chemistry. When the Station and Unit and Station Services Superintendents are unavailable, responsibility for site approval of exceptions to power reductions rests with the Unit Duty Officer. When the Manager, Nuclear Materials and Chemistry, NEO 2.17 Rev. O Date: 5/30/85 Page 6 of 11
is unavailable, responsibility for corporate approval of exceptions.to power reductions rests with the NUSCO Chemistry Duty.0fficer.

Sampling frequencies should be increased as needed during chemistry transients. All sampling frequencies shall meet or exceed the SGOG secondary water chemistry guidelines. Sampling frequencies for secondary water chemistry parameters which do not fall into the above categories shall be based upon NSSS vendor recommen-dations.
6.2.2 Sufficient supplies of chemical reagents and spare parts for analytical equipment shall be maintained to insure, with reasonable confidence, that specified analysis frequencies can be maintained. Alternate means of chemical analysis can be used as a backup if it is impractical to maintain a spare parts inventory, however, the alternate analysis must be of sufficient accuracy to determine if chemistry specifications are being met.
6.2.3 Exceptions to the guidelines specified in Sections 6.2.1 and 6.2.2 will be noted in the Management Status Report on Water Chemistry, as described in Section 6.6.
NEO 2.17 Rev. O Date: 5/30/85
