SUPPLEMENTAL INFORMATION: I. Introduction The U.S. Nuclear Regulatory Commission (NRC or Commission) is withdrawing Regulatory Guide (RG) 1.56, ‘‘Maintenance of Water Purity in Boiling Water Reactors,’’ Revision 1, dated July 1978. Revision 1 of RG 1.56 was issued for comment in July 1978 and never finalized. It was intended to support General Design Criterion (GDC) 14, ‘‘Reactor Coolant Pressure Boundary’’ and GDC 31, ‘‘Fracture Prevention of Reactor Coolant Pressure Boundary’’ of Appendix A, ‘‘General Design Criteria for Nuclear Power Plants,’’ in Title 10, Part 50, of the Code of Federal Regulations, ‘‘Domestic Licensing of Production and Utilization Facilities.’’ RG 1.56 describes an acceptable method for maintaining water purity levels in the reactor coolant in order to ensure that degradation of the reactor coolant pressure boundary is not exacerbated by poor chemistry conditions. However, degradation of the reactor coolant pressure boundary is generally a long-term process and other direct means to monitor and correct reactor coolant pressure boundary VerDate Nov<24>2008 18:05 Feb 18, 2010 Jkt 220001 degradation exist, which are controlled by regulations and plant technical specifications. For example, in-service inspection of components and primary coolant leakage limits are regulatory requirements that provide direct means to identify degradation of the reactor coolant pressure boundary. Therefore, requirements related to the chemistry program do not constitute initial conditions that are assumed in any design basis accident or transient related to reactor coolant system integrity. The staff considers water chemistry to be an operational issue for plants. If a licensee frequently repairs or replaces components because poor chemistry practices are causing degradation, then that is a cost the licensee must incur. It is in the licensee’s best interest to operate the plant with a chemistry regime that optimizes component performance. There is adequate industry-generated guidance available for licensees to develop a plant-specific water chemistry program. For example, the 2004 revision of the Electric Power Research Institute report BWRVIP–130: ‘‘BWR Water Chemistry’’ provides a framework for plant-specific chemistry programs. The industry routinely updates this guidance to incorporate the latest knowledge and lessons learned in the area of water chemistry. II. Further Information The withdrawal of RG 1.56 does not alter any prior or existing licensing commitments or conditions based on its use. The guidance provided in this regulatory guide no longer provides useful information. Regulatory guides may be withdrawn when their guidance is superseded by congressional action or no longer provides useful information.

SUPPLEMENTAL INFORMATION:

I. Introduction

    The U.S. Nuclear Regulatory Commission (NRC or Commission) is 
withdrawing Regulatory Guide (RG) 1.56, ``Maintenance of Water Purity 
in Boiling Water Reactors,'' Revision 1, dated July 1978. Revision 1 of 
RG 1.56 was issued for comment in July 1978 and never finalized. It was 
intended to support General Design Criterion (GDC) 14, ``Reactor 
Coolant Pressure Boundary'' and GDC 31, ``Fracture Prevention of 
Reactor Coolant Pressure Boundary'' of Appendix A, ``General Design 
Criteria for Nuclear Power Plants,'' in Title 10, Part 50, of the Code 
of Federal Regulations, ``Domestic Licensing of Production and 
Utilization Facilities.''
    RG 1.56 describes an acceptable method for maintaining water purity 
levels in the reactor coolant in order to ensure that degradation of 
the reactor coolant pressure boundary is not exacerbated by poor 
chemistry conditions. However, degradation of the reactor coolant 
pressure boundary is generally a long-term process and other direct 
means to monitor and correct reactor coolant pressure boundary 
degradation exist, which are controlled by regulations and plant 
technical specifications. For example, in-service inspection of 
components and primary coolant leakage limits are regulatory 
requirements that provide direct means to identify degradation of the 
reactor coolant pressure boundary. Therefore, requirements related to 
the chemistry program do not constitute initial conditions that are 
assumed in any design basis accident or transient related to reactor 
coolant system integrity.
    The staff considers water chemistry to be an operational issue for 
plants. If a licensee frequently repairs or replaces components because 
poor chemistry practices are causing degradation, then that is a cost 
the licensee must incur. It is in the licensee's best interest to 
operate the plant with a chemistry regime that optimizes component 
performance. There is adequate industry-generated guidance available 
for licensees to develop a plant-specific water chemistry program. For 
example, the 2004 revision of the Electric Power Research Institute 
report BWRVIP-130: ``BWR Water Chemistry'' provides a framework for 
plant-specific chemistry programs. The industry routinely updates this 
guidance to incorporate the latest knowledge and lessons learned in the 
area of water chemistry.

licensing commitments or conditions based on its use. The guidance 
provided in this regulatory guide no longer provides useful
