OPINION

JULIA SMITH GIBBONS, Circuit Judge.

Defendant-appellant Andrew Siemaszko appeals his conviction on three counts of concealing material facts and making false statements to the Nuclear Regulatory Commission (“NRC”) in violation of 18 U.S.C. §§ 1001 and 2. On appeal, Siemaszko argues that there was insufficient evidence to support his convictions and that the government’s presentation of evidence and an improper jury instruction constructively amended the indictment. For the following reasons, we find that there was sufficient evidence to support each of Siemaszko’s convictions and that Siemaszko failed to establish that a constructive *453 amendment of the indictment occurred. Therefore, we affirm.

I. Factual and Procedural Background

This case arises out of an incident that occurred in 2001 at the Davis-Besse Nuclear Power Station (“Davis-Besse” or “the plant”), which is located on the shores of Lake Erie near Toledo, Ohio, and is owned and operated by FirstEnergy Nuclear Operating Company (“FENOC”). Siemaszko began work at the plant in 1999 as the systems engineer in charge of reactor coolant systems. After a safety incident at a similar plant prompted the NRC to require inspections at all like plants by the end of 2001, FENOC successfully petitioned the NRC to permit Davis-Besse to operate without interruption and thus delay inspection until a scheduled refueling shutdown in spring 2002. Siemaszko’s involvement in preparing the documents that Davis-Besse submitted to the NRC in furtherance of the delayed inspection gave rise to his indictment on and subsequent conviction of three counts of concealing a material fact and making false statements to a United States agency. During the delayed inspection, Davis-Besse found five cracked nozzle heads and a football-sized cavity caused by boric acid erosion in the head of the reactor. The finding prompted NRC investigations into previous plant inspections and, eventually, the prosecution of Siemaszko.

A. Davis-Besse Nuclear Power Station

Davis-Besse is a two-loop, pressurized water reactor that is composed of a large cylindrical chamber filled with coolant water (“the Reactor Pressure Vessel” or “RPV”). Uranium rods at the core of the vessel fuel the nuclear reaction that heats the coolant water. The nuclear reaction is controlled by introducing boric acid and/or control rods into the reactor vessel. The control rods are inserted through sixty-nine penetration nozzles (tubes that are approximately four inches in diameter) that penetrate through the head of the reactor (approximately ten feet in diameter) into the reactor chamber. There is a gap between the RPV head and reflective metal insulation that encloses closure flanges and studs. The gap is narrowest at the top of the head, where it is only two inches wide. Control rod drive mechanisms (“CRDMs”) allow the operators to lower the control rods into the reactor to control the rate of the nuclear reaction, and, thus, the energy output. The nozzles are welded onto the vessel head using a J-groove on the underside of the steel head, which is 6.5 inches thick.

The internal walls of the RPV and the underside of the RPV head are covered in non-corrodible stainless steel, but the RPV and the external components are made of carbon steel, which is corrodible by the boric acid in the coolant water if it escapes the RPV. This can happen when the coolant water leaks through the flanges that connect the CRDMs to the nozzles above the RPV head. Davis-Besse had a history of flange leakage and developed the Boric Acid Corrosion Control Procedure (“BACCP”), which it implements during inspections, to address this problem.

Davis-Besse operates in two-year fuel cycles and, therefore, shuts down the reactor only during the biennial refueling outages (“RFOs”). Davis-Besse was scheduled to conduct RF013 (the thirteenth RFO conducted at Davis-Besse) in April 2002. In addition to permitting refueling, the RFOs are the primary opportunity for inspections and maintenance that cannot occur while the reactor is in operation. The RFOs at issue in this case are RFO 10 (1996), RFO 11 (1998), and RFO 12 (2000). During an RFO, in order to visually inspect the nozzles and the RPV head, oper *454 ators must insert a camera through a series of eighteen “weep holes” that are five by seven inches in size and that line the bottom of the RPV head above the head flange connecting the RPV head to the RPV. Because of the limited accessibility of the camera, it is impossible to visually inspect the very top of the RPV head and the nozzles located there. Siemaszko was in charge of inspecting and cleaning the RPV head during RF012 in 2000, but was not present during the RFOs in 1996 and 1998. Prasoon Goyal, another engineer at Davis-Besse, oversaw this task during RFO10 in 1996 and reviewed the inspection reports following RFOll and RFO 12. Another engineer, Peter Mainhardt, supervised inspection and cleaning during RFOll in 1998. As of 2001, Goyal continued to work at Davis-Besse as an engineer, and Mainhardt worked for FENOC as an independent contractor preparing for RFO 13.

The 1996 RPV head inspection lasted only one hour due to limitations on the technicians’ exposure to radiation. During that inspection, Goyal directed two technicians who were moving a camera on a pole across the vessel head. He watched on a monitor and narrated the camera location based on the “stud hole” numbers (the numbers on the studs between the weep holes). The nozzles are not numbered, so this is the only way to determine and document the condition of each nozzle based on the camera visual. Ed Chimahusky, a systems engineer in charge of coolant systems from 1991 to 1997, testified at Siemaszko’s trial that by using a camera through the weep holes, “[i]f you did the best you could, you could probably look at ... 70 percent of [the RPV head].” Goyal, in testimony and in a Potential Condition Adverse to Quality report (“PCAQ”) submitted to superiors after RFO 10, estimated that he was able to inspect fifty or sixty percent of the head area in 1996 and noted that it was difficult to estimate the amount of boron deposits on the head because of the limited visual inspection. In his PCAQ, Goyal attributed the boron deposits to flange leaks. The PCAQ also noted several deposits ranging in color from white to brown to rust. In both the PCAQ and in testimony, Goyal noted that the boron deposits and limited visual access prevented full implementation of the BACCP. Consequently, in the PCAQ, Goyal suggested modifications to the RPV head that would permit better access, such as installing access doors. The modifications were never made.

Mainhardt conducted a similar inspection with the help of technicians during RFO 11 in 1998. He testified that he found “[l]ots of flakes [of boric acid], ... also some fist-sized clumps ... which would be particles all stuck together,” “one area that kind of was pasty looking, ... maybe like a paste that hardened there,” and “some streaks on the control ride drive tubes [and around cracks in the insulation at the top of the head] that looked like milk.” Goyal reviewed Mainhardt’s PCAQ report and again faulted flange leaks with causing the boron deposits.
