NUCLEAR REGULATORY 

COMMISSION 

[NRC–2010–0052] 

Withdrawal of Regulatory Guide 

AGENCY: Nuclear Regulatory 

Commission. 

ACTION: Withdrawal of Regulatory Guide 

1.56, ‘‘Maintenance of Water Purity in 

Boiling Water Reactors.’’

Component Integrity, Office of Nuclear 

Reactor Regulation, U.S. Nuclear

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. 

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. 

Regulatory guides are available for 

inspection or downloading through the 

NRC’s public Web site under 

‘‘Regulatory Guides’’ in the NRC’s 

Electronic Reading Room at http:// 

www.nrc.gov/reading-rm/doccollections. Regulatory guides are also 

available for inspection at the NRC’s 

Public Document Room (PDR), Room O– 

1 F21, One White Flint North, 11555 

Rockville Pike, Rockville, Maryland 

20852–2738. The PDR’s mailing address 

is US NRC PDR, Washington, DC 

20555–0001. You can reach the staff by 

telephone at 301–415–4737 or 800–397– 

4209, by fax at 301–415–3548, and by email to pdr.resource@nrc.gov. 

Regulatory guides are not 

copyrighted, and NRC approval is not 

required to reproduce them.
